The constricted-plasma source, a rugged, clean, low-cost device with potential for applying thin films on everything from microchips to plastic wrap, has won a prestigious R&D 100 Award for its developers, André Anders of AFRD, Mike Rubin of Environmental Energy Technologies, and Michael Dickinson of Engineering.
Plasma sources produce "activated" gases (ionized or electrically excited gases) which are widely used in industry to lay a thin layer of crystalline or amorphous film on an underlying surface. Such films include the semiconducting layers that make up integrated circuits and light-emitting diodes (LEDs); the transparent conductors that are used in flat-panel displays; and the coatings on "smart windows" that control heat and light from the sun.
"The beauty of our source is that it can run with virtually any gas," Anders says. With nitrogen, nitrides such as gallium nitride can be formed to create blue light-emitting diodes and laser diodes, useful in manufacturing CD players, flat panel displays, and even traffic signals. With oxygen, the constricted plasma source (CPS) can help make a variety of oxides, including indium tin oxide, a promising "electrochromic" coating that allows the transparency of windows to be adjusted by hand. Using CPS, a process that now requires heating the glass to 400 degrees Celsius should be feasible at much lower temperatures, even near room temperature.
Existing plasma sources operate at low pressures and high energies. Common models that use a hot tungsten filament can react with some gases or contaminate the plasma. Models that use microwaves or radio-frequency energy are clean but very expensive, selling for up to $80,000. Any source of high-energy plasmas can cause so-called ion damage in fragile crystal structures.
By contrast, Berkeley Lab's CPS can operate at either low or high pressures to produce cold (low energy) plasmas with "a higher percentage of the desired species" of ionized gas. Low ionic energies (typically only a few electron volts) permit the formation of delicate crystalline films impossible to make using other kinds of plasma sources.
Anders describes the unique design of the CPS as "beautifully primitive. There's nothing to break." The trick is to force gas and electric current through a narrow constriction--a hole or series of holes in a plate between the source's negatively charged cathode and a positively charged anode. As pressure builds in the chamber behind the constriction, free electrons collide more frequently with the gas molecules, and bound electrons are stripped away more quickly, allowing ionization of the molecules at lower temperatures. The result is a gas of charged molecules and atoms and free electrons--a plasma. The electrons stream through the constriction, attracted toward the anode, which may be close to the constriction or far away behind the target, or may even be the target itself. Meanwhile the positively charged ions are attracted by the cathode and stay inside the chamber. The pressure builds until the less energetic ions are blown toward the target through the constriction, the only means of escape.
Cold is a relative term. The plasma produced by a CPS is called cold because the ions, atoms, and molecules are of comparatively low energy. The electrons, however, are hot--even a few electron volts translates to tens of thousands of degrees Kelvin--but have little mass. Whether cold and heavy or hot and light, neither type of particle does harm to delicate substrates.
In his first attempt to build a CPS, Anders used a thin glass tube only a couple of inches long, which allowed him to observe the plasma inside it glow as electrons and gas molecules collided; since the little device wasn't cooled, its plastic fittings melted within five minutes, "but that was long enough to show me that it worked," he says.
The CPS now comes in many sizes and configurations. In a typical CPS, a fist-sized, stainless steel cylinder with fittings for gas, electricity, and cooling water constitutes the high-pressure chamber; the constriction is a single hole in a plate capping the cylinder. A CPS can be built as a long, thin tube, or the constriction can take the form of a wide slit--or a straight row of holes, which works well for large-scale applications. Such a "quasi-linear" array about a foot long will soon be tested by a major window glass manufacturer; if it works well, it can be lengthened to as much as two meters.
A cold plasma source two meters wide would also be ideal for making, say, the kind of potato chip bags that are coated with shiny aluminum oxide inside to keep their contents fresh. The CPS can produce the needed enormous amounts of ionized oxygen at temperatures cool enough not to melt the wide plastic webs.
"Right now, glass coated with electrochromic or photochromic film is an expensive item," Anders says. "A luxury-car owner can afford a self-tinting windshield, but we'd also like to make variable-transparency glass cheap enough for a homeowner's windows."
Some of the CPS's possible uses are exotic, such as creating water-vapor plasmas for better ion-conducting hydrated films or implanting nitrogen ions in lithium, with the ultimate aim of making recyclable lithium batteries, a potential boon to the electric-car market. The CPS already promises cheaper, more reliable manufacture of a wide range of everyday products.

When software engineers Jerry Fiddler and David Wilner worked at Berkeley Lab in the 1970s and early '80s, they never guessed that their Lab experience would lead to the development of a software technology that is literally out of this world.
In 1981, the two co-founded Alameda-based Wind River Systems, the company that developed the software system now being used aboard the Pathfinder spacecraft on its Mars mission. The real-time operating system, called VxWorks, manages the spacecraft's computer, handling communications between the spacecraft and scientists at the Jet Propulsion Laboratory in Pasadena, Calif. Using VxWorks, the scientists are able to run scientific experiments and control the movements of the Sojourner rover as it explores the Martian surface.
Wilner says he and his partner credit much of the company's success to the experience they gained in the Lab's Real Time Systems Group, which provided software and computing support for the Laboratory.
"It was an incredible experience for me," Wilner said of his years at the Lab. "I learned software engineering at LBL." He said he and Fiddler had "terrific mentors" at the Lab, including Vic Elischer, who he calls "the godfather of Wind River Systems," and Van Jacobsen, who went on to develop the Multicast Backbone (MBone), a virtual network used on the Internet.
Wilner said he learned about software engineering at a time when no one knew much about it. "It was all very new in the '70s," he said. "I had no degree in software--no one did." He said the group grew from five-to-ten people in the beginning to 120 when he left--"a perfect time for starting a company. We started our engineering methods and software the correct way, which we learned at the Lab."
"The Lab moved me from Illinois to Berkeley," Fiddler said. "I had my masters' degree in computing sciences, but the Lab is where I learned software engineering."
Wilner said the things they were building 10 to 20 years ago at Berkeley Lab are being used in modern electronic equipment today. "The Pathfinder is using the same concept as the Super HILAC back in the 1970s," he said.
Fiddler and Wilner recently received a proclamation from the City of Berkeley in recognition of their work for the space program. "It is great to be recognized by the city since Wind River actually started in my garage in Berkeley," said Fiddler. "So even though we aren't located in Berkeley, we are still tied to that area."
"I am a pretty died-in-the-wool Berkeley character," Wilner said. "I went to Cal, and got my real education at the Lab."

As electrical appliances in homes become more specialized, often providing services once unavailable to the general public, they are using a growing amount of energy, even when switched off or not providing the service for which they were designed.
"Many household appliances draw power in their `standby' mode," says Alan Meier of the Environmental Energy Technologies Division's Energy Analysis Program. "These include common household appliances such as televisions, cable boxes, VCRs, answering machines, alarms, smoke detectors, cordless phones, fax machines, video games, even rechargeable electric toothbrushes."
Energy specialists call this "leaking electricity" because the devices are using energy without performing their principal function.
Meier and colleagues Steve Greenberg of Berkeley Lab and Leo Rainer of the Davis Energy Group estimate that the national power consumption lost to leaking electricity is 5 gigawatts (billion watts)--the equivalent of five standard power plants--and growing. They have also developed strategies to reduce this loss, including a circuit which reduces the power draw of appliances that need continuous energizing.
To determine how much electricity residences are leaking on average, Meier worked with several colleagues to measure the actual leakage of homes in California, Florida and Japan. Hidetoshi Nakagami of Japan's Jyukankyo Research Institute monitored electricity use in four Japanese houses; Danny Parker of the Florida Solar Energy Center studied a home in that state retrofitted for energy-efficiency; and Rainer studied six California homes, three new, and three with energy-efficient retrofits.
"Based on these measurements, and the saturations of the principal electricity-leaking appliances in American homes, we estimate that the average home leaks about 50 watts, or 450 kilowatt-hours per year," says Meier. "Since the average residential energy consumption in the U.S. is nearly 10,000 kilowatt-hours per year, this is about 5 percent of a home's electricity use--roughly two-thirds the consumption of a new refrigerator."
The U.S. houses in the study drew anywhere from 5 to 23 percent of the houses' total power consumption, while the Japanese houses drew between 10 and 17 percent. The fraction of leaking electricity in U.S. and Japanese homes is similar because the U.S. houses in the study were more energy-efficient than the average U.S. house. Japanese homes use less electricity than U.S. homes, according to Meier.
"Newer models of some appliances will leak less electricity in the future," Meier says. "Televisions, for example, currently draw about 40 watts to maintain their remote control and instant-on features, but new models on the drawing board will draw 5 to 20 watts. Computer, monitors, fax machines and some other appliances are also getting more efficient, thanks to the Environmental Protection Agency's Energy Star voluntary guidelines."
But Meier says that other trends, like the growth in certain appliances and changes to building codes, are increasing electricity leakage. "The saturation in American homes of emerging electronic appliances, like burglar alarms, garage door openers, telephone answering machines, cordless phones and others is increasing," he says.
Stricter building codes require developers to install ground fault circuit interrupter-protected outlets. Older codes mandated these only in bathrooms to reduce the danger of electrical shock. Now, kitchens and other special rooms must have them too. Codes also now demand the hard-wiring of three or four smoke alarms into the home's electrical system: in the bedrooms, hallway and garage.
Reducing or eliminating leaking electricity would have a number of other benefits besides saving energy, which of course reduces the environmental impacts of energy generation.
"It would remove a potential fire hazard or a danger of shock--when the appliance is `off,' it is truly off," says Meier. Leaking electricity also generates heat, which increases a home's air conditioning load. And, the "leaked" electricity has a poor power factor, meaning that it can degrade the performance of sophisticated electronic equipment, such as the home personal computer.
Meier and his colleagues have been studying ways to reduce these leaks and have found some technical options. The low voltage power supply (the little black box that plugs into the wall outlet) is the culprit in some appliances. Cheaper models have high power losses, up to 3 watts each. Higher quality, Underwriters Laboratory-certified power supplies already exist that have a three-way on-ready-off switch on the side. In the off position, an appliance equipped with one of these is truly turned off.
Existing photovoltaic technology provides another solution for consumers with certain battery-based appliances, like portable computers or cordless telephones. Solar PV-charge kits can take the place of the household outlet for keeping some batteries charged.
To address the power draw of appliances that need continuous energizing, such as TVs and VCRs, Meier, Greenberg and Rainer have designed a circuit that draws power only when a small battery mounted in the appliance needs power. The rest of the time, the circuit switches itself off. Manufacturers could design these circuits into their appliances. Another way of reducing leaks would be to improve the power supplies they use.
As under secretary, Moniz would be responsible for issues involving science and technology, fundamental research, the environment, and national security. The nominee is well credentialed for this role. He currently heads the physics department at MIT. From July 1995 to January 1997 he served as associate director for science in the White House Office of Science and Technology Policy. He has a doctorate in theoretical physics from Stanford University and is a previous director of MIT's Bates Linear Accelerator Center. According to a White House press release, in his new position Moniz "will be responsible for integrating the (DOE) laboratories into a cohesive national system and for strengthening the links to academia and the private sector while further enhancing laboratory core competencies."
Reicher currently serves as a senior adviser to Energy Secretary Federico Peña, and was chief of staff to Hazel O'Leary from 1993 to 1997. Before joining the Clinton Administration he was a senior attorney for the Natural Resources Defense Council. Like Moniz, Reicher holds an advanced degree (law) from Stanford.
The House spending bill would raise NSF's $3.367 billion budget request by $120 million, including $90 million to fund a new South Pole research station. The Senate version would only add $10 million to the request, mainly because it did not include funds for the new Antarctic station. NIH, however, continued to be the biggest winner for federally funded science. A House funding panel has already voted to give NIH a 6-percent boost in 1998 (more than double the increase sought by President Clinton), raising its budget to $13.5 billion. The Senate version of the bill is expected to be even more generous. Receiving the largest share of the increase would be human genome research, with a raise of 12 percent above spending in FY97.

Photo: Today is the birthday of Berkeley Lab founder Ernest O. Lawrence, who was born on Aug. 8, 1901. Starting in a small lab on the UC Berkeley campus, Lawrence guided his Laboratory until his death in 1958. By then, the Lab had grown in size and moved up the hill to its present location. Winner of the 1939 Nobel prize in physics for the invention of the cyclotron, Lawrence is generally acknowledged as the Father of Big Science. His idea that complex scientific problems are best solved by multidisciplinary teams remains the foundation of the Lab's approach to research.

Frank Lindgren, an emeritous member of the Life Sciences Division, has been awarded the Special Recognition Award by the Arteriosclerosis Council of the American Heart Association. The award, bestowed at the 69th annual meeting of the AHA, acknowledges Lindgren's many contributions in the area of lipoprotein measurements and the association of elevated cholesterol with increased risk for heart disease. Lindgren is measurements of various lipoproteins by analytic ultracentrifugation are considered the "gold standard" for measuring the "good" and "bad" lipoproteins.
Under the category of oldies but goodies, a team of Tasmanian botanists claim to have found the world's oldest plant, a shrub born more than 43,000 years ago. If the claim holds up, this Lomatia tasmanica, a member of the Proteaceae family, otherwise known as King's holly, will usurp the previous record holder, a box huckleberry in Pennsylvania, which is a mere child, 13,000 years in age. Meanwhile, a team of Portugese scientists say they have discovered the world's oldest dinosaur embryo and the first to be found in Europe. Found in 140-million-year-old sediment about 60 kilometers north of Lisbon, the Jurassic-era embryo was in a cache of eggs. It was 18 centimeters long and is believed to be a three-toed meat eater.
Under the category of science or fiction, a growing number of professional and amateur athletes, and couch potatoes, too, are strapping or taping magnets to their bodies in search of therapeutic relief for strained muscles, or sounder sleep. "Biomagnetic therapy" actually dates back centuries--Cleopatra supposedly wore a magnet on her face to preserve her beauty--but the recent marketing boom has made biomagnets one of today's hottest trends in medicine. Medical magnets ranging from 800 to 4,000 gauss in field strength have become a billion dollar industry, according to both Time and Newsweek magazines. The claims are that muscle injuries generate positive magnetic fields and that the application of a negative field can relieve the pain and speed healing. There has been no scientific evidence to support such claims, but the prevailing medical wisdom seems to hold that the most likely harm to come from biomagnets will be to consumer wallets.

In a noontime forum on community issues last week, EH&S Division Director David McGraw recalled the time when Lab Director Charles Shank vowed to make the Laboratory--historically living in quiet excellence on the hill above UC Berkeley--a more visible presence in the community.
Through effort, circumstance and achievement, he said, the Lab has earned a measure of success in its drive for recognition, though it is not always the visibility the Director had in mind. With a higher profile has come closer scrutiny from the community, and with it a set of issues that challenge Berkeley Lab to communicate its programs and its values more effectively.
McGraw related this paradox to about 60 employees attending the first brown bag "Community Issues Forum" Aug. 1 in Perseverance Hall. This and future lunchtime meetings are designed to brief employees on issues affecting the Laboratory in the community and to seek ways to enhance Lab partnerships with civic and community leaders.
"We owe you the assurance that we're safe and we're managing our programs appropriately," McGraw told the audience. "We're in a paradigm shift; we must become a little more humble, and we have to explain ourselves in a way that offers comfort to those with concerns."
He noted that employees are also members of the communities in which they live, "and we need ambassadors" to convey information about the Laboratory and the valuable programs conducted here.
The first step in building bridges to the community is educating the messengers. Hence the inauguration of this briefing series, sponsored by the Office of Planning and Communications. At session one, two issues currently in the news were explained and discussed--the new Hazardous Waste Handling Facility and its related permit modification request that is being challenged in court, and the National Tritium Labeling Facility (NTLF) and community concerns about its emissions into the environment.
Robin Wendt, group leader for Waste Management, reviewed the nature and characteristics of the hazardous waste generated at the Laboratory and its preparation for treatment and disposal at the new facility. The permit modification request, he explained, seeks to redistribute regulated storage capacities in two categories of waste while asking to treat waste 10 new ways.
"We did an exhaustive analysis of environmental impacts and took extreme care in responding to every question and concern of the public," he said. "We feel we have a facility that is second to none, and we're convinced it represents an extremely low risk to the workers or the environment. It is extraordinarily well designed and constructed."
That hasn't convinced certain members of the Berkeley community, who have sued the Laboratory to engage in a full-scale environmental impact report, according to the Lab's environmental counsel, Nancy Shepard.
"Through our risk analysis, we concluded that there would be no significant new environmental impact" as a result of the changes in the permit modification, Shepard said. Hence the Lab's decision to issue a "negative declaration" under the California Environmental Quality Act (CEQA). The lawsuit, filed by a group of Oakland and Berkeley citizens--and supported with $25,000 in grants from the two city councils--challenges the Laboratory's CEQA determination and requests a more rigorous review.
"We believe (the litigants') concern is generally over the issue of an increase in waste, even though our actions would only result in a net increase of 45 gallons," Shepard said.
The tritium issue has also been the focus of citizen concerns, this time over radioactivity in the environment. NTLF manager Phil Williams explained the purpose and value of research at the facility, which involves "tagging" molecules with a radioactive form of hydrogen so that their transport and function can be traced in biological systems. Advances in a variety of pharmaceutical and therapeutic investigations, for diseases like cancer and Alzheimer's, are dependent upon such unique studies, according to Williams.
"Through this methodology, you can find molecules in a crowd," Williams said. "And it results in an incredibly small change to the molecule. Tritium can be detected with extremely high sensitivity."
The vision of the National Institutes of Health, whose funding supports the NTLF, for the facility's mission is to be a multi-disciplinary research unit, a major national experimental facility, a place to educate and train researchers, and a place to transfer knowledge to industry and university users. In the last 18 months, visitors from 17 states and six countries have used the NTLF, Williams said.
Ron Pauer, Berkeley Lab's manager for emissions monitoring on site, explained the nature of tritium emissions from the NTLF (minute amounts of water vapor, resulting in human doses far below national safety standards) and his program of continuous measurements in air, soil, water and plants.
Pauer noted the community's focus on potentially endangered children at the Lawrence Hall of Science, and presented three pieces of evidence that counter those fears--the Laboratory's own recent risk assessment, a voluntary University-conducted employee urinalysis program at the LHS, and a letter from the Environmental Protection Agency that assures the Berkeley City School Board of children's safety at the museum.
Nonetheless, Pauer said, Berkeley Lab has committed $100,000 to a third-party monitoring and analysis program in the City, guided by the Tritium Issues Work Group, that will independently address the health and safety issues. He said a sampling plan is expected within the next month.
Ron Kolb, head for Public Communications, described the first issues briefing session as "an experiment, to see what employees need to be better informed about the issues facing us." He encouraged attendees and others to forward ideas to him about future briefings, subjects of interest, and other effective methods to communicate and interact with the laboratory community.
A second brown-bag briefing is expected in September.
When Gordon Ferguson heads to the Lab each morning, he makes sure he has two important things with him--his science experiments for the day and his child-like enthusiasm. With his background in science and experience as a teacher, Ferguson says he feels right at home as director of the Laboratory's Science Exploration Camp (SEC) for Lab children.
During the school year, Ferguson chairs the science department at Chaboya Middle School in San Jose. He says he welcomes the opportunity to direct a camp for kids and to share some of the curriculum he has developed. "I hope to provide an environment in which the wonder of science can be conveyed in a fun and relaxed manner," he says.
This year about 30 children and relatives of Lab employees are attending the camp, which consists of six one-week sessions that provide a mixture of science and recreational activities. The kids, who range in age from 7 to 11, meet in the mornings for a dose of science--usually a child-scale experiment or lesson conducted by Ferguson or a volunteer Lab scientist. They also pay visits to various Lab facilities, such as the Advanced Light Source, and take field trips to UC's Lawrence Hall of Science and the Botanical Garden.
In the afternoons, the camp offers recreational activities such as swimming at Strawberry Canyon and trips to local parks.
The camp has a different hands-on science theme every week, which allows the kids to explore such topics as energy, properties of matter, chemistry, biology, geology, and space. Students are also given a journal in which to record their observations and experiences.
Along with Ferguson, there are four camp counselors, and a number of parent volunteers. Jil Geller of the Earth Sciences Division is a parent volunteer and member of the camp's non-profit SEC committee. She says the committee has worked hard to build continuity between the Lab and the program.
"The program serves the Lab community," she says. "The schedule is set up to accommodate Lab parents and their working hours. As a working parent with kids at this camp, it allows me to go to work with my kids and leave with my kids. They know what I do here and I know they are close by, which makes me feel great." She says parents are welcome to have lunch with their kids while they're attending the camp.
The program, now in its third year, has the support of Lab management. "It is really exciting to see how the kids have taken to this," said Lab Deputy Director Klaus Berkner, who stopped by the camp to watch the kids learn how to make nitrogen ice cream. "It is amazing that Gordon can keep them all entertained at such different age ranges."
Ferguson says he is learning a lot from his time with the kids. "The best lesson I have learned is to never stop looking for the `wows' in life," he said. "Each day can be filled with wonder."
The camp runs from 9 a.m. to 4 p.m. Monday through Friday, with before and after childcare for those who need it. The cost is $160 per week, which includes field trip costs and special discount kids' meals in the cafeteria. Operating costs of the program are supported by camp tuition.

Currents is printed on recycled and recyclable paper, using soy-based inks. You can recycle your copy by placing it in one of the "white paper" receptacles provided by Richmond Sanitary.
If you are one of the growing number of students and employees who prefer to commute on foot or bike, you may be interested in a new campus map just released by UC Berkeley.
The easy-to-read map shows the walking, hiking and bike trails that run along and between city streets in the areas surrounding campus and Berkeley Lab. Using the map, it may even be possible to find shortcuts that could lop extra time off your daily commute.
The map was created by the campus offices of Public Affairs and Resource Development, with input from Ron Kolb, head of Berkeley Lab Public Communi-cations, and Lab facilities planner Rich McClure.
One side of the map shows the campus and Lab buildings and roads. The other side shows parts of Berkeley, Oakland, Albany, Kensington, El Cerrito, Emeryville, Piedmont, and Richmond, as well as Tilden Regional Park and waterfront areas stretching from Richmond to West Oakland.
Using color-coded lines and symbols, the map show trails, paths, stairways, as well as street barriers and grades.
"Now people can sit at home and plot their path to work," said McClure. "We try and treat all transportation modes equally, and that is why this map is so important for us."
McClure said the map is the only one of its kind that he's aware of that is available to the public. "It will be a tremendous asset for people who want to walk or bike to work, as well as for visitors who need to learn their way around."
The maps may be purchased for $3 from the Employee Buying Service in the Lab cafeteria. They are also available at the UC Berkeley Visitor Center, and from Cody's Books and the Campus Textbook Exchange in Berkeley, where prices may vary.

The Facilities Department has recently completed the first phase of the ongoing Sanitary Sewer Restoration Project, which will bring the Lab new pipes and better flow in many portions of the site. However, in much of the Lab, there is an aging and fragile sewer system that relies entirely on gravity flow. No sewer system, and certainly not ours, is constructed to receive and dispose of foreign materials such as tampons, solid objects, and wads of paper towels.
Facilities and EH&S ask the cooperation of employees in allowing the Lab's sewers to flow smoothly and do the job for which they are intended. Please do not dispose of inappropriate objects to the toilets, and do use the receptacles provided for sanitary supplies. Remember also that no hazardous materials should be disposed of in any drains at all.
