For six grueling hours he sat flat on a wooden platform in the back of a helicopter, half in, half out, strapped to a harness, legs braced against the landing poles, staring down thousands of feet through the viewfinder as the chopper swung in the wind, circled canyons, and rose to 3,000 feet only to dive back to tree-top level soon thereafter. The thrill-seeker was no stunt man, however, but Lab photographer Roy Kaltschmidt, taking aerial shots of the Laboratory and surrounding areas to record changes in topography, document the foliage program, and update the photo record of the Laboratory's changing landscape.
"This was truly a joyride," he laughs. "I was shooting like mad, taking it all in and appreciating being there."
This is hardly the first time the veteran photographer has tackled lofty assignments. Previous photo shoots have taken him from the top of the Golden Gate Bridge, to plane rides over the Sacramento Delta, to dangling inside the cavernous acrylic vessel of the neutrino SNO experiment in Canada. Each of these shoots presented its own thrill, and this latest one -- soaring over the Bay Area -- rated near the very top, Kaltschmidt says.
"Taking pictures from a plane is not nearly as exciting. With a copter you can go so much lower, almost to the treetops, or come to a stationary point. It's a real treat."
The shots were commissioned by the Lab's Facilities Department. The last aerial shoot was done in 1994, and much has changed over the past five years. New buildings and parking lots have been added, old ones underwent face lifts, and the vegetation patterns have come and gone with the seasons.
To meet the varying demands of this assignment, Kaltschmidt focused as much on detail -- sides of buildings and foliage in small canyons, for instance -- as on the big picture: depicting Berkeley Lab's position within the Bay Area. The result: a stunning collection of photographs, one of which will soon hang outside the Director's office.
"This was the first time aerials were shot in the spring, when the hills are all green," says Kaltschmidt. "In the past they did the shooting during the summer, when the hills were scorched."
Armed with two cameras and 40 rolls of film, Kaltschmidt and his team took off from a private hangar at the Oakland Airport on a gorgeous day at the end of March, ready to tackle three two-hour-long shooting sessions. Getting to that point, however, was no easy task.
The Lab had contracted with a helicopter firm in San Jose long before, with the shooting originally planned for the second week in February. But the weather would not cooperate.
Such a complex shooting session is contingent on many factors, not the least of which is a clear, sunny and relatively windless day. In addition, the helicopter has to be available on short notice once the weather conditions are in place, and Kaltschmidt had requested one specific helicopter with removable doors for this assignment. Finally, the pilot needed to be ready to take off at that time as well.
Even on a clear day, however, the adventuresome Lab shooter was still subject to nature's whims. "The wind in the canyons can be tricky," he says. "If you don't get the shot right away, you need to do a circle and come back. We often had to do a couple of passes to get a specific shot."
All along he had to keep track of where each shot was taken, picking markers to get his bearing and visually locking in on various spots while circling around.
While the assignment had specific documentary purposes, Kaltschmidt never lost track of the shoot's artistic potential, always looking for visually innovative perspectives and playing with angles, shadows and different lenses to put his personal imprint on the job.
"Previously they shot 'bombardier photos,' he laughs. "All looking down to the top of the buildings. And most of them are pretty ugly on top! We went down to lower elevations, looking into buildings, getting a sense of the shape and look, as opposed to a rooftop view. I always try to think of new things or new ways to show things, whether I deal with science or landscape or people. It has to be visually stimulating for audiences both inside and outside the Lab."
The photo shoot was so successful that Kaltschmidt plans to put together what he calls "a virtual reality tour into Berkeley Lab" -- a Quicktime picture series that would take the viewer all the way from the Golden Gate Bridge, across the Bay Area and Berkeley Lab, down to the rooftop of the ALS. The only short-term impediment to the project is reducing the file size of the pictures down enough for the movie to be manageable online.
For all the fun in the skies, Kaltschmidt admits his "joyride" took just about everything out of him.
"I was mentally wiped out by the end of the day," he says. "And physically, too. My legs were sore from bracing. I felt like a vegetable the next day."
That being said, Kaltschmidt cannot wait for the next assignment -- the more adventuresome, it seems, the better. It is indeed difficult to imagine what's left to challenge Kaltschmidt. After all, he has taken his camera all the way from the bowels of the earth in a mine shaft, to balloon, plane and helicopter rides. So what's left?
"Well, I've never been in outer space!" he jokes. Or does he?

The National Energy Research Scientific Computing Center (NERSC) has selected an IBM RS/6000 SP system as the center's next-generation supercomputer. When fully installed, the new machine will have a peak capacity of three trillion calculations per second.
The IBM system was chosen based on its ability to handle actual scientific codes and tests designed to ensure the computer's capability as a full-production computing system in NERSC.
When fully installed the system will provide four to five times the total current computational power of NERSC, already one of the most powerful supercomputing sites in the world. This agreement -- a fixed-price, five-year contract for $33 million -- is the largest single procurement in the 68-year history of Berkeley Lab.
"Although some computing centers describe their system's performance in terms of theoretical peak computing, we look at our systems in terms of how much they can enhance our clients' ability to solve large-scale scientific problems," said Bill Kramer, head of NERSC's High Performance Computing Department and leader of the procurement effort. "That's the real measure of performance in our view."
The new system, which will incorporate IBM's newest processor and interconnect technology, will be installed in two phases. Phase I, scheduled to begin this June, will consist of an RS/6000 SP with 304 of the 2-CPU POWER3 SMP nodes, with two processors per node. In all, Phase I will have 512 processors for computing and a peak performance of 410 gigaflops, or 410 billion calculations per second. Phase II, scheduled to be implemented by December 2000, will consist of 152 16-processor nodes. The entire system will have 2,048 processors dedicated to large-scale scientific computing and a peak performance capability of more than three teraflops, or three trillion calculations per second.
As part of the purchasing contract, NERSC will work with IBM to develop means to assess and improve the effectiveness of the system in a production environment. While the theoretical peak performance of supercomputers can be extraordinary, it does not always represent real-world performance. "Theoretical computer speed is comparable to the top end of a car's speed-ometer, " Kramer said. "And while your car might be able to do 150 mph on the open road, you're really more interested in how it will carry out your day-to-day driving chores."
To ensure that the new NERSC system is well-suited to its anticipated work load, NERSC and IBM have agreed to develop and test a "SUPER" (System Utilization Performance Effectiveness Rating) benchmark measurement for the new computer.
"While we anticipate that most of our users will appreciate the new machine's high speed capability," Kramer added, "our main concern is that they have the computing resources they need, when they need it. This contract ensures the system will live up to NERSC's standards for performance and reliability."
The SP is a highly scalable system made up of building blocks called SMP nodes. This architecture will allow NERSC users to increase the size of their computations and make the results more meaningful.
"The continuing partnership between IBM and the Department of Energy is further testimony to what can be accomplished when two leaders in the field of computational science push the boundaries of conventional thinking," said Rodney Adkins, general manager of IBM RS/6000. "I can't think of anything more noble than being a part of making lives better, whether it's through helping design cleaner engines or increasing life-saving knowledge about our environment through climate modeling."
The new system will also allow NERSC to run a variety of different-sized computations simultaneously, thereby providing faster turnaround of results for users across the country.
NERSC provides high-performance scientific computing and data storage resources to about 2,500 researchers at national labs, universities and industry across the nation who are working on DOE-funded programs such as combustion, climate modeling, fusion energy, materials science, and computational biology. NERSC's seven supercomputers, the largest of which is a 640-processor Cray T3E-900, are utilized 24 hours a day, seven days a week, and are running more than 95 percent of the time, therefore needing highly reliable, high-speed computeres.

Auto air conditioners can make all the difference in the world on a sweltering summer day. But all of us who first have to step into a burning-hot car, braving the suffocating heat wave while trying to keep our hands off the sizzling steering wheel, know we still have a long way to go in controlling our comfort level -- not to mention the ensuing energy use.
A research collaboration involving Berkeley Lab's Engineering and Environmental Energy Technologies Divisions, however, may have come up with a cool solution: the world's first thermally insulated car. What's more, with Lab-developed insulation inside the body panels and insulated window units, the car can get better gas mileage than a regular car while staying cooler in the summer and warmer in the winter.
"This is the first time that a car manufacturer is studying thermal insulation to reduce heating and cooling loads," says Deb Hopkins of the Engineering Division. "No one has ever looked at it before in the auto industry."
The Thermal Management Project is a collaboration between the Lab and Ford Visteon, an enterprise of the Ford Motor Company, which is also funding the project. It is also associated with the Partnership for Next Generation Vehicles, which brings together researchers from the US government and a private consortium, the United States Council for Automotive Research, funded by General Motors, Ford and Daimler-Chrysler.
In February Ford Visteon sent a factory-new Ford Taurus to the Lab. The car was stripped down to sheet metal in just two hours by a technician from Roush Industries, who flew out from Detroit. Its doors, windows, and other parts were retrofitted here with Lab-developed insulation before they were taken back and reassembled in another car in Detroit.
Ford Visteon chose Berkeley Lab's patented gas-filled panel (GFP) insulation over other competitors because of the panel's high performance-to-weight ratio. "In adding two to five centimeters of insulation we only increased the weight of the car door by 120 grams," says Daniel Türler of the Engineering Division. The weight savings achieved by GFPs over other insulation options allowed the installation of double pane windows necessary for thermal performance.
In addition, a spectrally-selective solar-control film was applied to the inner surface of the windshield, and double-pane insulated glazing units were used for the side and back windows. The solar control film serves to create a filter that rejects ultra-violet and infrared wavelengths, resulting in significantly reduced heat gain into the interior of the car and degradation of interior surfaces.
GFPs use thin polymer-film cellular baffles and low-conductivity gas to create a lightweight device with extraordinary thermal insulation properties. These hermetic plastic bags can take on a variety of shapes and sizes and can be up to three times as effective as conventional foam insulation.
"The aim of this project," says Hopkins, "is to develop technology that helps reduce a car's total weight by 40 percent. This will raise the gas mileage of a Ford Taurus to 80 miles per gallon without a loss of performance or decreased occupant comfort. Adding insulation to the car allows its air conditioning unit to be smaller, which gives you a weight reduction that improves mileage."
The team of researchers and technicians had only three weeks to install insulated gas-filled panels in the doors and the rest of the car's body and to replace the side and back windows with the insulated glazing units. Hopkins, Türler, Phil Rizzo, and EETD's Brent Griffith and Howdy Goudey, along with technicians in five of the Lab's shops, worked around the clock to retrofit the car by the March deadline. Goudey and Rizzo manufactured gas-filled panels in EETD's infrared-thermography lab, a facility designed for developing and testing insulation and window technology. With Türler they installed the panels in the car body. Meanwhile, Paul LaBerge of EETD designed boxes to securely pack the odd shaped parts for shipment to Detroit.
Everyone involved went the extra mile to ensure that the project was completed on time. Never before have so many panels of the experimental insulation been assembled. Jim O'Neill and Bill Gath of the Technical Services Department were instrumental in providing technical support. The plastics shop made the contoured interior pane of the dual-pane glazing systems that were installed on the car's back and side windows.
The coating shop manufactured customized plastic parts with aluminum coatings. The refrigeration shop drained and tuned the car's air-conditioner on short notice. And the carpentry shop made shipping crates to deliver the modified parts to Detroit.
Their work completed on time, Hopkins, Türler and Goudey went to Detroit in March, taking along the windows, insulated doors and other parts they developed. At Roush Industries they reinstalled the parts in another Taurus.
Said Türler, "A Ford team began testing the thermal characteristics of the refit Taurus in an environmental chamber under hot and cold conditions, as well as under driving conditions. The car is also undergoing wind tunnel testing in a facility in Canada. Their testing should be complete later this year."
Although the first phase of Berkeley Lab's work is complete, the team would like to do some additional testing and evaluation of the car, as well as to work with Ford on refining and improving the design of the insulation.

Under the new structure, the operations offices in Oakland, Chicago and Oak Ridge will report to the Office of Science; the Albuquerque and Nevada offices will report to Defense Programs; and the Idaho, Savannah River and Richland operations offices, along with the Ohio and Rocky Flats field offices and the Office of River Protection in Richland, will report to Environmental Management.
A Field Management Council chaired by Deputy Secretary T. J. Glauthier will be established to assure "consistent implementation of DOE policy" in areas such as environment, safety and health, safeguards and security, and business management.
Until now, DOE's field offices have administratively reported to a single office in headquarters, as well as to various program offices.
Prepared by DOE's Office of General Counsel, the report focused on CRADAs (cooperative research and development agreements). A CRADA allows a lab to provide personnel, facilities, equipment or other resources to the private sector towards the conduct of specific research that addresses DOE missions.
Technology transfer is a DOE mission that creates public benefits, the report said, but disputes can arise when a licensed lab technology displaces existing products in the marketplace. DOE seeks to head off these problems by having its field offices review and approve CRADAs. The Office of Inspector General also routinely audits selected elements of tech-transfer programs.-- Lynn Yarris

In the wake of the unexpected departure of four community members from the Tritium Issues Work Group, the group's co-chairs and its remaining members vowed to move ahead on developing a tritium sampling plan for areas at and around Berkeley Lab's National Tritium Labeling Facility (NTLF).
The Work Group was established more than two years ago as an inter-agency and community forum to assess, through environmental testing, the public effect of small amounts of tritium emitted at the NTLF. It has been co-chaired by representatives of the Environmental Protection Agency and the state's Department of Health Services.
With an independent sampling program as its ultimate goal, the Work Group has had difficulty gaining consensus on its scope of work. At its monthly meeting on April 21, Work Group members affiliated with the Committee to Minimize Toxic Waste and the Community Environmental Advisory Commission walked out in frustration. Their prepared statement cited disagreements over Work Group priorities, accusations that the Department of Energy and Berkeley Lab have withheld data, and their desire for an "independent" consultant to do a scoping study.
In a prepared statement, the Laboratory called the withdrawal "unfortunate" and restated its commitment to support independent sampling as the best way to resolve questions involving public safety. This view was shared by the Work Group's leadership, who scheduled a final review of the sampling plan for the next meeting in May.
"We also pledge to involve the community and continue dialogue with all interested parties, the City of Berkeley, and our regulators as the process continues," the Laboratory statement said.
The Lab reiterated its view that operations at the NTLF are safe and pose no public health hazard. "Annual emissions from the facility are less than three percent of the federal public health standard," the statement said.
Independent sampling will be supported by $100,000 in Laboratory funds pledged by Director Charles Shank.
The Laboratory has repeatedly denied accusations that it has been refusing to release information relevant to the process. A pending request by the Committee to Minimize Toxic Waste for historic data, which the Laboratory has stated will involve more than $40,000 in staff time to collect, has been submitted as a Freedom of Information Act request to the Department of Energy. A community plea to waive those collection costs has thus far been denied.
"With the exception of one broad, labor-intensive demand for information," the Lab statement said, "the Laboratory has willingly and responsibly responded to all reasonable requests for information. The pending...request is costly and not needed to perform the Work Group's primary charge."
Director Shank met last week with Berkeley City Mayor Shirley Dean, City Manager James Keene, and CEAC chairman John Selawsky in an effort to resolve differences and move the process forward. They agreed to continue to seek common ground in the coming weeks.-- Ron Kolb
Richard Saykally, a chemist with Berkeley Lab's Chemical Sciences Division and a professor with UC Berkeley's Chemistry Department, has been elected as one of 60 new members of the National Academy of Sciences. Election to membership in the Academy is considered one of the highest honors that can be accorded a U.S. scientist or engineer.
Saykally is an expert in laser and molecular spectroscopy and specializes in the ultrasensitive detection of trace species. He and his research group are perhaps best known for recent discoveries into the detailed nature of water cluster structure and their investigation of the role of carbon in interstellar dust. Saykally also led the development of the Cavity Ringdown direct laser absorption spectrometer.
This year's NAS election brings the total number of active Academy members to 1,825.

"You see a lot less diesel smoke these days," says Arlon Hunt of the Environmental Energy Technologies Division, "because the manufacturers have done a good job of getting rid of most of the large exhaust particles -- the ones that are easy to see. The challenge is to measure what's not so easy to see -- and these particles may be the most dangerous of all."
Hunt and his colleagues, Mary Quinby-Hunt and Ian Shepherd, have recently tested a prototype optical instrument that can measure diesel exhaust accurately and completely within a few seconds, while the engine is running. So far their "scatterometer" has been used only in the laboratory, but with simple modifications similar devices could be used to measure individual vehicle emissions or to sample environmental air quality in the field.
"Light scattering gives the most complete possible information you can get without interfering with a system," says Hunt, who for over 30 years has been using combined theoretical and instrumental approaches to light scattering to study all sorts of systems, including the interstellar medium, the sickling of hemoglobin in human blood, transparent aerogel ceramics, and even octopus sperm.
Recently, because of interest in the environmental hazards of small particles, Hunt and his colleagues have turned their attention to measuring particle size and composition in diesel exhaust.
"When you are looking at elastic scattering of light -- that is, systems where the light that comes out is the same wavelength as the light that went in -- the easiest thing to do is to measure opacity," says Hunt. "And until recently, `how black is it?' was about the only question asked about diesel soot. But diesel exhaust isn't black anymore. Opacity measurements tell you very little."
The technique devised by Hunt and his colleagues measures linear and circular polarization as well as intensity. These variables are arranged in a matrix representing the scattering of the light at all angles. Only four of a possible 16 elements are needed to convey all the information about light intensity and polarization states that can be gleaned from a suspension of spherical aerosol particles.
Hunt's group first ran the exhaust from a one-cylinder diesel engine through a gadget with a jawbreaking name: the Angle-Scanning Polarization-Modulation Nephelometer, or POLNEPH.
Several features suited the POLNEPH to its task of identifying the nature, size and density of exhaust particles. The linear and circular polarization of a laser beam is modulated 50 thousand times a second. There is no glass or plastic window where the beam passes through the sample -- only an open gap in the pipe that brings the exhaust through the center of the device.
Around this central point, a long arm with a photomultiplier tube at its end rotates through 180 degrees, recording the total intensity and polarization states of the light at each scattering angle. A computer traces out curves as the values change with the angle of measurement, generating four distinctive graphs.
"Unfortunately, there is no good theory that can tell us how to get from this data back to the kind of particles that produced it," says Hunt. "However, if the particles are spherical, or nearly so, we can calculate a large number of alternative models based on simple Mie calculations, using different kinds and sizes of particles in different mixtures. We compare the real data with these models, and where all four curves fit simultaneously we can be sure we know what we're looking at."
Particles in the exhaust of modern diesels are in fact nearly spherical under all running conditions. "Under no-load conditions, the particles are very small," Hunt says, "and their refractive index suggests that they are primarily water droplets or dilute sulfuric acid. Under full load conditions, the particles are larger and darker, although they don't fit the model of pure soot. The particles we observe under engine loading are probably combinations of water and soot."
Using POLNEPH, Hunt and his colleagues determined that approximations based on the refractive index for dry soot give completely erroneous results -- as does the Rayleigh theory, even though Rayleigh equations are often used to describe scattering from diesel engines.
While even the largest particles in the exhaust from a modern engine tend to be spherical, older diesel engines may produce much larger, nonspherical particles for which simple calculations are inadequate. Their presence is revealed by measuring a matrix element other than the four used in the aerosol calculation.
With POLNEPH, Hunt's group analyzed emissions from older engines by applying a program developed by Mary Quinby-Hunt under a grant from the National Energy Research Scientific Computing Center (NERSC).
An elaboration of the "coupled dipole approximation" first suggested by Berkeley Lab astrophysicist Carl Pennypacker to model particles in the interstellar medium, the program generates model particles of arbitrary size by adding spherical nanoparticles in a random-walk pattern. Using NERSC's Cray T3E supercomputer, Quinby-Hunt is building up a library of scattering signals from likely particulate shapes, for determination of emission constituents.
Conventional methods of measuring diesel exhaust are unable to rapidly track changes in particle emissions under changing conditions such as acceleration under load. The POLNEPH setup has proved itself capable of accurate particle-size determination under slowly changing conditions.
But because better measurement speed and portability are needed, Hunt and his colleagues designed and built a smaller, more rugged device dubbed the Diesel Particle Scatterometer.
"The Scatterometer uses the same method of modulating the polarization of the laser beam, and the same open viewing of the sample," explains Ian Shepherd, "but instead of a rotating arm, it uses 12 different photomultiplier tubes that measure different scattering angles simultaneously."
The data from the photomultipliers is converted from analogue to digital form and processed using a dedicated personal computer. Continuous measurements can be made as often as one to ten times a second.
"To proceed with an instrument capable of analyzing diesel exhaust from the smallest spherical particles to the largest non-spherical particles, in real time, right where the engine is," says Arlon Hunt, "all we need now is the funding." The Scatterometer is the prototype of a device that can go into the garage, to the loading dock, or on the highway to yield accurate measurements of diesel exhaust particles.

Someday "scatterometers" will be taken into the garage, to the loading dock, or onto the highway to analyze particles in diesel exhaust emitted by engines such as the ones powering this truck.
