LBL fills key communications posts

By Mike Wooldridge,

In a move that should help streamline communication on the Hill and bolster the Lab's visibility, LBL has filled two high-level communications posts.

Ron Kolb, formerly director of News and Public Affairs for the UC Office of the President, has been named the Lab's head for public communications.

Ruby Tebelak, formerly of Lawrence Livermore National Laboratory and Northrop Corporation, has been appointed head of the Technical and Electronic Information Department.

Kolb, who took his position in April, will be responsible for public information programs at the Lab, including media relations, institutional publications, and internal and external communications.

"I sense a genuine desire at the Lab to promote its distinct identity and to be more widely known as one of the premier American centers of scientific excellence," Kolb says. "There are wonderful stories to tell, and my public information colleagues and I are committed to finding the most effective ways to tell them."

Kolb has served as a communications consultant to LBL for the last year and a half, during which he conducted a detailed analysis of the Lab's communications programs and assisted in the development of its first comprehensive communications plan. He also served as staff on Lab Director Charles Shank's Task Force on Communications.

Shank says he welcomes Kolb's appointment. "I am pleased to have a person of Ron's leadership abilities and communications skills to head our public communications. It is particularly important during this time when a distinct identity must be strongly asserted with regional and national audiences."

Kolb succeeds Art Tressler, who retired as head of Public Information in October 1993.

A former daily newspaper reporter and editor at the Riverside Press-Enterprise, Kolb worked from 1974 to 1984 at UC Riverside, where he was manager of Information Services. He directed all publicity efforts regarding research achievements, including 25th anniversary activities and related promotions for Riverside's respected Agricultural Experiment Station.

He moved to the UC President's Office, then in Berkeley, in 1984 as its director of News and Communications, overseeing all media relations, print, broadcast and internal communications functions for the nine-campus system's headquarters.

In 1988, Kolb was named director of News and Public Affairs at UC. His duties included community and public relations activities. He also developed and managed the communications program for the Keck Observatory in Hawaii, home of the world's largest optical telescope, and coordinated university-wide efforts to celebrate UC's 125th anniversary in 1993.

Tebelak, who took over TEID in March, says her primary goals are to grow a satisfied client base, earn a reputation for excellence, and develop a dedicated, motivated team. Reaching these goals, she says, will enhance internal communication and enable LBL to reach its digital potential--through technology such as multimedia and the World Wide Web.

"My ultimate goal is to be the model for all the national labs when it comes to professional communication and digital innovation," she says. "The digital revolution is going to have as great an impact on the way people communicate as the invention of the printing press."

Her plans include creating an electronic library system, establishing publishing standards, and developing dynamic home pages for the World Wide Web. She also plans to establish electronic publishing benchmarks in areas such as digital photography, 3-D electronic presentations and video, and the use of DOE-approved Standard Generalized Markup Language (SGML).

Tebelak takes over from ICSD Division Deputy Sandy Merola, who served as acting head of the department. In her first months, she has already taken steps towards her goal of an electronic workplace. She has established a Web task force to ensure that TEID sets the highest standards for LBL pages on the Web.

Most of her time to date, however, has been spent acquainting herself with the rest of TEID through one-on-one meetings with employees. Once those are finished, she plans to meet with every division and program to listen to their needs and discuss how TEID can partner with them to produce quality, cost-effective technical publications. "How we perform is just as important as what we produce," she says.

Tebelak brings a variety of communications experience to the job--as a technical writer and editor at LLNL, a technical publications manager and proposal engineer at Northrop Corp., an educator at the University of California, and as a commercial artist.

At Livermore, she worked in the Defense and Nuclear Technologies Directorate Assurance Office, writing compliance documentation and safety analysis reports, giving workshops on technical presentations, and training other writers and editors. At Northrop, she managed the publication of aerospace proposals and reports. She developed an electronic communications link between Northrop's California division and MacDonald Douglas's Missouri division, which cut publications costs in half.

Even with her new job at LBL, Tebelak continues her connection with her college alma mater, the University of Missouri. A frequent guest lecturer and a member of the school's English Advisory Board, she is currently helping the university establish a degree program in technical writing.

Ultrafast scanning microscope catches atoms in action

By Jeffery Kahn,

Materials Sciences Division researchers have devised a breakthrough process that gives them the ability to image and stop the action of atomic-scale events in picosecond freeze-frames.

Ultrafast scanning probe microscopy promises to give researchers the ability to look at atoms in the time frames at which atomic-scale phenomena unfold. Scientists believe they will be able to image electrons as they move in their enigmatic paths across the atomic lattice of a semiconductor. Conceivably, a series of images of a plant transforming sunlight into chemical energy--in essence, a movie of photosynthesis--could be recorded.

MSD's Shimon Weiss, UC Berkeley graduate student David Botkin, and MSD Director Daniel Chemla have led the effort to develop this new family of microscopes. Other contributors include MSD's Frank Ogletree and Miquel Salmeron. The inventors say the full potential of the technique is yet to be defined.

"This dynamic technique is very exciting and very broad, but also very new," Chemla says. "At this stage, we are still exploring which approaches will be most effective."

First describing their efforts in the Nov. 1, 1993 issue of Applied Physics Letters, the researchers reported that they have obtained images with simultaneous 2-picosecond and 50-angstrom resolution.

Ultrafast scanning probe microscopy results from the wedding of two cutting-edge tools. Scanning probe microscopes--including the scanning tunneling microscope and the atomic force microscope--can image details as small as a single atom. Femtosecond lasers, developed by LBL Director Charles Shank, provide pulses of light that last a millionth of a billionth of a second. Coupling the microscope and the laser, the new ultrafast instruments use the laser pulse to optically activate a switch integrated in the tip of a scanning tunneling microscope. The technique captures images of ultrafast events, improving the time resolution attainable with the scanning tunneling microscope by nine orders of magnitude.

Weiss says that when a series of successive, time lapse images is combined, the result is a movie of surface dynamics. Each image involves two pulses of light. The first pulse excites the surface being investigated. This excitation can be electronic or vibronic, generating either a pulse of electrons or an acoustic wave (phonon).

The second light pulse activates the switch, turning on the microscope for the duration of the pulse, and allowing it to image the surface just for that instant. The Auston switch used in the instrument, which has subpicosecond speed, was invented by David Auston, a former colleague of Chemla and Shank's at AT&T Bell Laboratories and a UC Berkeley graduate.

Chemla said the motivation underlying the development of ultrafast microscopy can be found in the growing interest in nanoscale features and phenomena by both chemists and physicists. Chemla himself is particularly interested in semiconductors.

"Each time we create a new generation of chips," he says, "we reduce their dimensions. Up until now, making it smaller has meant that everything runs faster. But at a certain scale--and we are now approaching that--the standard design rules begin to break down. Electronic, magnetic, and optical properties are altered. They become dependent on size and shape."

To guide the design of future generations of semiconductors, researchers would like to be able to zoom in and stop the action, exploring just what happens in the nanoscale world. For example, launching a very fast packet of electrons and then recording their whereabouts as they cross a semiconductor device would reveal the processes governing their motions. Due to quantum effects, electrons "tunnel" across gaps, but exactly when and where tunneling will take place is unknown. Chemla says the ultrafast microscope now makes it feasible for researchers to observe the dynamics of tunneling.

Before movies can be made of surface dynamics, the researchers first must understand the physics of the instrument. "The first thing we have to do," says Weiss, "is understand what we are observing when we measure a single point. Right now, we are investigating and characterizing the physics of tunneling--in particular, the quantum capacitance effect--at a single point. This is really the first science to be done with this new technique."

Ultrafast, stop-action "movies" long in coming

The ability to stop the action and take an image of what happens in a given instant has a relatively short history.

Although the camera began to emerge in the 1500s, the first true photograph was not made until 1826. It was not until 1877 that the first successful photographs of motion--of a running horse--were captured. Working in California, British photographer Eadweard Muybridge set up a row of cameras with strings attached to their shutters. As a horse ran by, it broke the strings, tripped the shutters, and created a series of photos that amazed the world.

Since then, faster and faster cameras have been developed. Consumers can now buy models with shutter speeds as fast as 1/2000th of a second.

Science has developed a number of imaging techniques other than photography. Scanning probe microscopes, invented in the early 1980s, can zoom in and image individual atoms, but essentially, they have been unable to record motion.

LBL's new ultrafast scanning probe microscopes change that. Events evolving at an atomic level often occur in lightning-like time frames. The new microscopes finally give science the ability to observe these ephemeral events. They will capture moments that are measured in picoseconds, or trillionths of a second.

Lab to ship Bevatron blocks to BNL

By Lynn Yarris,

An LBL plan to transport approximately 1,500 concrete shielding blocks from the Bevatron to Brookhaven National Laboratory (BNL) for re-use with the Relativistic Heavy Ion Collider (RHIC) was unveiled last week to officials with the city of Berkeley. The plan, which will save taxpayers millions of dollars and spare needless use of precious waste burial space, was well received by the officials.

Rick Gough of the Accelerator and Fusion Research Division made the presentation on behalf of the Laboratory. He was accompanied by community relations specialist Shaun Fennessey, NEPA/CEQA coordinator Carol Kielusiak, health physicist Roger Kloepping, and project manager Bob Stevenson.

Gough described a plan under which the blocks would be moved through Berkeley by truck during the summer months over a period of four years, starting this year and ending in 1998. The blocks will be taken to the freight yards in Richmond and transported by rail to New York.

"The closure of the Bevatron has made available a large amount of surplus concrete that can be re-used," Gough told the officials. He called the re-use of the Bevatron shielding blocks an "extraordinary opportunity for waste minimization and taxpayer savings."

Since the closure of the Bevatron in 1993, the question has been how to dismantle the facility, which occupies approximately 7,200 square meters of valuable research space. Of particular concern was the disposal of the concrete blocks that served as protection from incidental radiation produced during the accelerator's operation. The blocks average about 10 tons in weight, with the largest weighing 30 tons. Though some blocks contain low-levels of residual radiation, these levels are several hundred times below Department of Transportation requirements for shipment as non-radioactive materials.

All of the alternative disposal options would be more costly in terms of money and environmental impact than shipment to BNL. At present, the only approved disposal site for these blocks is the DOE waste repository at Hanford, Wash. Transporting the blocks to Hanford for burial would cost about $41 million--about 10 times the cost of shipping them to BNL. The blocks would take up approximately 4,500 cubic meters of burial space.

The shipment schedule Gough presented to the Berkeley city officials calls for about 20 truckloads of blocks to be moved over a two-day period each week between the business hours of 7 a.m. and 4 p.m. The trucks would follow a prescribed route down Hearst Avenue, across Oxford Street, and down University Avenue to Interstate 80. It is expected that 115 truckloads will be hauled away this summer, followed by 400 in 1996, 215 in 1997 and 55 in 1998. This schedule was arranged to coordinate with the construction needs of RHIC.

Attending the presentation for the city of Berkeley were traffic engineer Chuck De Leuw, hazards specialist Jennifer Krebs, senior transportation planner Susie Sanderson, and fire marshall Lucky Thomas.

Currents survey draws varied views

In a first-ever assessment of reader opinions last winter, Currents received 325 responses to a questionnaire sent to a random sample of scientists and engineers, administrative and technical staff, and students at LBL. It was conducted to evaluate Currents' effectiveness and to ensure that it reflects the needs and interests of its audience.

Almost 90 percent of respondents said they consider Currents to be a valuable communications tool that they find either very important to their laboratory experience or interesting to read. Only six said they never read the paper, while 79 percent said they read almost every issue. About half said they read virtually everything in the publication. The comments sections, however, showed a variety of opinions regarding what people want from their employee newspaper (see sidebar, page 3).

Of the article or feature categories listed for comment, the cafeteria menu drew the least interest--68 percent of those surveyed rarely or never read the menu. On the other hand, the flea market attracted 80 percent of the readers and, after the front page, was the second most popular section.

Other well-read categories included science and engineering research articles (88 percent read them "often" or "sometimes"), feature articles (91 percent), and announcements and coverage of events (85 percent).

The majority of respondents also said they considered the overall appearance of Currents to be attractive (24 percent) or adequate (71 percent).

Strong reader interest was expressed for audience participation features such as letters to the editor and a readers' questions section. Respondents also encouraged the publication of short science highlights from divisions, in addition to the longer science pieces.

Individual comments solicited from survey participants focused on a wide range of suggestions and concerns (see accompanying article). These included calls for more feature stories on the non-scientific support staff, "how-to" articles, employee opinion forums, and more stories on issues from the Department of Energy and the University of California.

Numerous responses cited Currents' value as a unifying laboratory vehicle that promotes a sense of community.

The editor wishes to thank everyone who took the time to express their views. Other comments from Currents readers are encouraged and should be forwarded to the Public Information Department. The responses will be considered as part of an ongoing evaluation process of design and content and will contribute to future changes.

Sampling of survey comments

Last winter, a number of Currents readers participated in a survey in which they were asked to comment on various aspects of the newspaper (see accompanying article). The following is a selection of comments and suggestions retrieved from the survey, some of which have been acted on, some of which are being considered, and all of which are greatly appreciated. To those who did not participate in the survey, we hope to hear from you next time. You are also welcome to send comments to us at any time via e-mail (, fax (X6641), or phone (X4014).

In memoriam: Gary S. Wagman

Gary S. Wagman, a computer scientist in the Physics Division's Particle Data Group (PDG), died on April 21 after a long illness. He was 41.

In addition to his courage and meticulousness, Wagman will be best remembered for his technical contributions to PDG's Review of Particle Properties, a biennial compilation of particle data considered by many high-energy physicists as the "Bible" of their field.

When he began at the Lab in 1985, each issue of the Review was assembled by hand from 40,000 card images. Wagman used his relational-database expertise to electronically integrate the Review, streamlining the publication process and virtually eliminating paste-up.

"Gary was instrumental in bringing the Review from its backward state in 1984 to the valuable document it is today," said Physics Division Director Bob Cahn. "His contributions to the division, the Lab, and the entire high-energy physics community were great."

Last fall, Wagman was recognized for his service to the Lab with an Outstanding Performance Award. In accepting the honor he replied, "I was only doing my job."

When his health began to fail, Wagman insisted that PDG hire his replacement immediately, so he could train him. "Gary saw what he did for the Lab as more than a job," said PDG's Charles Wohl. "It was a legacy."

Outside of his work at the Lab, Wagman was an avid traveler. As a teenager, he spent time at an Israeli kibbutz, and later visited Europe, Egypt, India, and Mexico. He also enjoyed woodworking, and spent much of his spare time remodeling his Victorian home in San Francisco.

Wagman is survived by his mother, Freda, and brother, Adam, both of Houston, Texas. His friends and co-workers in PDG request that donations in his name be made to Project Open Hand in San Francisco.

As was expected, last week's announcement by Energy Secretary Hazel O'Leary regarding DOE's "Strategic Realignment and Downsizing Initiative" (see Currents, May 5) played to mixed reviews in Congress. Supporters hailed the changes as a reasoned approach to reducing the size of government, while critics protested that the cuts did nothing to dissuade them from seeking to abolish the Department. Some Republicans even applauded O'Leary for her proposals, calling her "courageous" and saying she'd taken a "business approach" to making changes. Other found her proposals "disappointing" and said there were not enough specifics." The latest issue of Inside Energy, a weekly report on DOE published by McGraw-Hill, states that "few in Congress believe (O'Leary's) plan will do much to blunt efforts in both the House and the Senate to move a bill this year that would abolish the Department and disperse many of its functions to other agencies."


A report released this week by the Women's Leadership Institute at Mills College said that despite recent gains, the number of women leaders in science is far too low and more aggressive policies are needed to break the "glass ceiling." Among Americans holding doctorates in physics, math, chemistry, engineering, and computer sciences, fewer than 15 percent are women. About 40 percent of new medical doctors are women but the top ranks at medical schools remain overwhelmingly male. There are some encouraging signs, however. According to the report, women are now receiving nearly 40 percent of the doctorates in biology and 35 percent in chemistry. At the undergraduate level, women are near parity. For example, in 1991, women earned 44 percent of all bachelor's degrees awarded in science and engineering. However, women are still missing from the top roles. The study shows that the number of women on the tenure track at universities in the science and engineering fields has not significantly changed in decades. The report's prescription for change is to hire more women for top spots, invite more to be keynote speakers at major conventions and meetings, nominate more women for prestigious prizes, and put more women on committees in charge of hiring, promotions, and awards.


A panel of the National Academy of Sciences' Committee on Science, Engineering and Public Policy has rejected the call for modifying Ph.D. training to abbreviate research requirements for scientists not planning academic careers, and the idea of imposing controls on graduate enrollments. The issue of whether scientific doctorates are overeducated has been debated since the 1970s. Soliciting opinions from industry as well as academia, the NAS committee found solid support for not changing the essence of the scientific Ph.D., despite changes in employment and funding opportunities for researchers. The report, however, did advocate de-emphasizing research assistantships in favor of training grants, and giving students a much broader range of skills--"especially the ability to communicate complex ideas to non-specialists and the ability to work well in teams." The panel also called for "a national database on employment options and trends" that would include up-to-the-minute information on graduate programs, financial aid, and placement rates. Copies of the report, "Reshaping the Graduate Education of Scientists and Engineers" are available from the National Academy Press. Call 1-800-624-6242.

Element 106 name change being reconsidered

By Lynn Yarris,

Responding to an international wave of criticism surrounding the decision to remove the name "seaborgium" from element 106 and impose name changes on other transuranium elements as well, the executive committee of the International Union of Pure and Applied Chemistry (IUPAC) has recommended that the organization's decision be reconsidered.

This week's issue of Chemical and Engineering News (C&EN) reports that IUPAC's executive committee is urging that the organization reopen public discussion of the names proposed for all the transuranium elements from 101 to 109. A final decision on the matter will be made in August.

Last fall, the IUPAC nomenclature committee stunned the scientific community by rejecting the names proposed for elements 104 to 108 by their discoverers and submitting their own names instead (see Currents, Oct. 14, 1994). These new names were published as "definitive" in IUPAC's official journal, Pure and Applied Chemistry.

IUPAC's decision met immediate opposition from leading scientists and scientific organizations throughout the world. The strongest criticism was directed towards the removal of the name seaborgium from element 106. This element was discovered in 1974 at LBL by a team of researchers led by LBL physicist Albert Ghiorso and LLNL chemist Kenneth Hulet, who named it in honor of Glenn T. Seaborg, Nobel Prize winner in chemistry, and associate director-at-large of LBL.

Reaction to the IUPAC decision was typified by the response of LBL Director Charles Shank, who said, "There has never been any debate about the right of acknowledged discoverers to name an element." Shank said the Laboratory would "strongly defend this privilege." Many others joined the fight and in November, the nomenclature committee of the American Chemical Society (ACS) rejected the IUPAC names and unanimously endorsed the names given elements 104 to 108 by their American and German discoverers.

According to the C&EN report, the IUPAC executive committee has bowed to the pressure and is now recommending that the IUPAC names be reverted back to a "provisional" status. Such a reversion of names already published in the IUPAC journal as "definitive" would be unprecedented. However, it would allow for the standard IUPAC process of public debate on the proposed names to take place--a process IUPAC previously by-passed.

If the names of 106 and the other transuranium elements in question are submitted for public debate, chemists will have five months to submit their comments through one of 19 centers around the world. The U.S. center is located at the ACS Journals Department in Columbus, Ohio. Final recommendations on the names would then be submitted for ratification by IUPAC at its 1997 council meeting.

Emergency drill on Tuesday

The laboratory will conduct its annual earthquake drill at 10 a.m. on Tuesday, May 16. The public address system will be used to announce a simulated earthquake, followed by instructions on how to take refuge by ducking under a desk, table or workbench and "holding on" until the shaking stops.

Following the "duck, cover and hold" drill, all employees will be asked to evacuate their building and proceed to their designated assembly area. The duration of this phase of the drill should not exceed 10 minutes. EVERYONE SHOULD RETURN TO WORK BY 10:10 A.M.

Phase II of the drill includes activation of the Lab's Emergency Command Center and includes participation of emergency response groups only. Questions should be directed to Don Bell or Mark Turner at X6016 or X6554.

Patent Department

From time to time, the attorneys and patent agents in LBL's Patent Department receive questions from individual researchers, the answers to which may be of general interest to others in the Laboratory. The following is one such example. If you have questions for the Patent Department, call X7058.

Q: Photocopying--how much is too much?

A: Almost everyone photocopies scientific journal articles, and almost everyone knows that the articles are copyrighted. This does not mean, however, that almost everyone is breaking the law. Photocopying an article is not a copyright violation so long as the photocopying is "fair use" of the work.

So what is fair use? It depends on three major things: the purpose of the use; the nature of the copyrighted work; and the market effect.

No one wants to stifle scientific research, so use for research purposes is generally okay, particularly if the copyrighted materials are being used to produce new works. The nature of scientific articles also favors a liberal approach to fair use. Facts cannot be copyrighted, only expression. Since science is heavily fact-based (compared, say, to poetry or short stories), use of scientific articles is usually appropriate.

The most important factor in the context of scientific articles, though, is market effect. No one expects every scientist to have his or her own subscriptions to every journal in existence. At the same time, if you photocopy material from a journal so regularly that you are effectively photocopying instead of subscribing, that is a problem.

The bottom line is that fair use is a judgment call. Don't worry too much about photocopying library copies of an article you need as background for your work. Do worry about making copies from Science every week for every member of your lab.
