LBL Currents -- May 27, 1994

Sudbury Neutrino Observatory--SNO work goes on

By Lynn Yarris,

Last July, LBL celebrated the completion of the 18-meter, stainless-steel geodesic sphere that is to be a major component of the Sudbury Neutrino Observatory (SNO). While the Petaluma, Calif., ceremony marked the completion of the sphere--which was subsequently shipped to Sudbury, Canada--LBL's contribution to the construction phase of SNO continued.

Scientists, engineers, and designers in the Nuclear Science and Engineering divisions, under the leadership of NSD physicist Kevin Lesko, have completed work on the panel arrays that, when attached to the geodesic sphere, will house will house 9,522 of the extremely sensitive light-detectors called photomultiplier tubes. It is the design and placement of SNO's photomultiplier tubes that will enable the facility to fulfill its scientific mission.

SNO is a collaboration involving more than 60 scientists from a dozen laboratories and universities in the United States, Canada, and United Kingdom. Its mission is to answer some of the most perplexing questions about neutrinos, the particles emitted from the sun and from supernovae. Neutrinos are intriguing in part because they are so ghostlike. One could pass untouched through a wall of lead stretching from the earth to the moon.

Operating from a cavern more than a mile underground, SNO will be the first detector sensitive enough to measure not only ordinary electron neutrinos, but also the much more rare muon and tau neutrinos. This unprecedented sensitivity stems in part from a design that maximizes SNO's light-collecting capabilities.

The SNO detector, which is suspended in a vast pool of purified water, consists of the geodesic sphere, the photomultiplier tubes attached to it, and an acrylic vessel, inside the sphere, that is filled with 1,000 tons of heavy water (deuterium oxide or D2O). When neutrinos passing through the heavy water interact with deuterium nuclei, flashes of light, called Cerenkov radiation, are emitted. The photomultiplier tubes detect these light flashes and convert them into electronic signals that scientists can analyze.

"It is vital for the success of any neutrino experiment that as many photons as possible be detected," says Lesko. "Therefore, we had to squeeze as many photomultiplier tubes as possible onto the geodesic dome while maintaining an adequate layer of water shielding between the tubes and the cavity walls of the SNO site."

The need for densely packed photomultiplier tubes was complicated by the requirement that each photomultiplier tube be individually aimed and that the entire assembly be water-tight. The design demands were made even more difficult because the components making up the tubes came from three different countries (England, Canada, and Japan), and all had to be assembled, tested, disassembled, transported, and reassembled under cleanroom conditions.

To meet this multifaceted challenge, Gary Koehler, an LBL mechanical engineer associate and the SNO project's senior designer, "checkered" the surface of the sphere with 751 panels that come in five different shapes, each of which is built up from repeating patterns of hexagons. The result is a honeycomb pattern that covers 70 percent of the sphere with light-collecting devices.

"It is an incredible problem to take a sphere and break it up into repeating elements," says Lesko. "Complex 3D models on computers had to be developed to translate Gary's design into an engineering design."

A mounting system was also needed that would allow easy alignment of the panels and give SNO's spherical structure the flexibility to go from being empty to being flooded with water. Engineer Yoichi Kajiyama and mechanical designer Dave Beck assisted Koehler on this aspect of the design. Their solution was a three-point ball and socket mount that permits each panel to be aimed by hand according to positions pre-set by computer, and provides stability to the sphere whether it is empty or full. In addition, they connected the entire collection of panels through a series of corrosion-resistant plastic skirts that make the sphere 99.95 percent water tight.

Once the design was completed, the panel components were fabricated by two Bay Area firms, Precision Plastics of South San Francisco, and Stoesser Industries of Mountain View. Finished components were sent to LBL where they were tested for low-background radiation contamination, then assembled into panels and shipped to Canada.

The SNO experiment will last at least 10 years and is expected to record between 10 and 20 neutrinos each day. NSD physicist Eric Norman will lead LBL's participation in the research phase of the project.

Japanese industry may have lessons for LBL

By Jeffery Kahn,

Japan's industrial strength is not merely the sum of its many technological successes, says professor Fumio Kodama of the University of Tokyo. Rather, it represents the success of a new method of innovation.

Kodama spoke at LBL on Monday, May 23, as part of the lecture series, "Science and Technology in a Competitive World," jointly sponsored by LBL and UC Berkeley.

Japan probably did not set out to invent a new way of developing, manufacturing, and marketing products, Kodama said. But gradually and unconsciously, a technological paradigm-shift occurred, creating a Japanese method of doing business that is very different from the American way.

He said the dimensions of the Japanese method extend far beyond the factory floor. They include research and development, manufacturing, business diversification, and even the process of innovation.

An author, government advisor, and member of the Engineering Academy of Japan, Kodama is professor of Science, Technology, and Industry at the University's Research Center for Advanced Science and Technology.

In remarks germane to LBL and the technology transfer mission of the national labs, he said product development in Japan does not start with science, but with the consumer. He said that in America, science feeds new technology into a pipeline with the expectation that a flow of new products will result.

Kodama said the Japanese prefer to begin product development by identifying what people want. He said this "demand articulation" is different from marketing and cited the case of video cassette recorders (VCRs).

The Ampex Corp. of California invented the videotape recorder in 1956. The machine was quite expensive and sold strictly to professional broadcasters. Toshiba, and later Sony, realized that residential consumers would buy and use VCRs if sold at the right price. Having articulated demand, the Japanese then began work on the technology, which resulted in the development of a very different machine.

Patterns of product innovation between America and Japan likewise are different. Kodama said although major scientific breakthroughs occur much more often in America than in Japan, this does not seem to translate into a commercial advantage for the United States. He said single scientific breakthroughs rarely result in new products. Rather, multiple breakthroughs are often required, as is a maturation and learning process.

Instead of relying on breakthroughs, Japanese companies prefer to combine or fuse several technologies. This approach has been so successful that despite the dearth of Japanese breakthroughs, Japanese companies are major holders of U.S. patents. In fact, Kodama said, in terms of the numbers of new U.S. patents applied for, many of the current top-ranking companies are Japanese.

Kodama said, to be successful, LBL's technology transfer efforts should rely strongly on interactions with industry. He said Japanese companies look beyond their own doors for emerging technologies. In fact, learning about new developments elsewhere is considered the responsibility of every employee.

At Meteorology Lab, a volt is a volt is a volt

By Mike Wooldridge, MAWooldridge

When is a volt not a volt, or a kilogram not a kilogram? While most people have little reason to ponder such philosophical questions, the staff of LBL's Metrology Lab grapple with them every day. The facility is the arbiter of truth when it comes to weights and measures at LBL, making sure the voltmeters, scales, and other instruments on the Hill are accurate.

"When a scientist reports in a paper that an instrument reads one volt, they need to be confident that it is indeed one volt," says Mike Bell, unit leader of the Metrology Lab. "The only way to have confidence that an instrument reads correctly is through calibrations that can be traced to national standards. This is what we provide."

The lab is staffed by technicians Bruce Gray and Mike Sawada, who between them gained 33 years of metrology experience in the U.S. Air Force.

The Metrology Lab began decades ago as a support facility for physics projects such as the Bevatron and HILAC. The facility built and serviced the thousands of electrical meters and chart recorders needed to run the massive accelerators. As time went on, the facility took on the task of calibrating instruments throughout the Laboratory.

The facility now maintains a number of precision devices to check everything from pH meters to thermometers. It also keeps a selection of standard weights used to calibrate scales and balances, from 5-kg cylinders to milligram-sized flakes of foil. (Calibration at LBL is also performed by the Environment, Health and Safety Division, which tests safety equipment such as fume hoods, and Mechanical Metrology, which handles length standards and precision dimensional measurements.)

The Metrology Lab's instruments are tuned to the strict standards of the National Institute of Standards of Technology (NIST) in Gaithersburg, Md., home of the official measures of the kilogram, second, meter, and kelvin in the United States. By using the resources available at the Metrology Lab, LBL scientists can be confident that their own measurements are traceable to these reference points.

The measurement standards were tweaked slightly in January, 1990, Sawada says, when an international agreement equalized the official weights and measures worldwide. "Before 1990, everyone had slightly different standards. Germany had a volt, Russia had a different volt, and we had a different one, too."

Bell emphasizes that attention to standards should become more important as LBL develops a stronger relationship with private companies, which generally have much stricter requirements for instrument calibration.

"As we develop closer ties with industry through Cooperative Research and Development Agreements (CRADAs) and tech transfer, industry is going to ask what our quality assurance standards are," Bell says.

Researchers interested in using the Metrology Lab's services should contact Bruce Gray or Mike Sawada at X5360.

Screening for skin cancer

There's still time to sign up for the Health Services Department's annual Skin Cancer Screening Clinic, to be held from 8 a.m. to noon on Friday, June 3, at Bldg. 26. Patients will be seen by a physician, and all questionable findings will be examined by Dr. Edward Ringrose and Dr. Elizabeth Ringrose, both Berkeley dermatologists. Call X6266 for an appointment. Please plan to take the LBL shuttle to your appointment as parking is very limited.

According to a new study in May's Journal of the American Academy of Dermatology, "Skin cancer now appears to be as common as all other types of cancer combined." Scientists doubled their estimate for the number of Americans who get non-melanoma skin cancer--the common, less serious type that, nonetheless, accounts for more than 1,200 deaths and countless disfiguring surgeries a year.

Most skin cancer is curable, but the costs of surgery and other treatments are substantial. Those costs could be decreased if people avoided sun exposure and had regular checkups.

The most deadly form of skin cancer, malignant melanoma, has soared in recent years--from 19,000 cases in the U.S. in 1984 to 26,000 in 1987. More than 7,800 of those patients died in that time.

With summer approaching everyone should know the warning signs of melanoma and the appropriate precautions.

Most moles are benign. This checklist can help identify those that may need medical attention:

* Does the mole itch?

* Is it bigger than the blunt end of a pencil?

* Is it growing?

* Does it have a ragged, irregular outline?

* Does it have mixed shades of brown and black?

* Is the mole inflamed or reddish on the edge?

* Is it bleeding, oozing, or forming a crust?

Such moles do not necessarily indicate melanoma, but they should be checked by a doctor.

You can also lower your risk by observing a few rules:

* Avoid the midday sun, between 10 a.m. and 3 p.m.

* Use sunscreens with a sun protection factor of at least 15; apply liberally before exposure and every two or three hours while in the sun.

* Wear a wide-brimmed hat, long-sleeved shirt and long pants when working in the sun.

* Keep children under 6 months old out of the sun. Use sunscreen on older children, and minimize their exposure.

* Examine your skin regularly for changes in moles, freckles, and skin discolorations.

Cafeteria shut-down

The LBL cafeteria will be closed for remodeling from Friday, June 3, through Friday, June 10. There will be a catering truck in the cafeteria parking lot to handle breakfast and lunch during this period.

The last day to drop off film in the Qualex Photo drop box (in the cafeteria lobby) before the shutdown is Wednesday, June 1st.

During the shutdown, the Employee Buying Service will be headquartered in Bldg. 90-1136B, the office of EBS representative Helen Coleman. She will have postage stamps and postcards for sale, discount coupon packages for amusement parks, and finished film orders from Qualex. Coleman is in her office from 8 a.m. to 2 p.m., Mondays, Wednesdays, and Fridays. You may contact Coleman at X7138 to arrange for her to mail finished film orders via lab mail.

The cafeteria will be open for business again on Monday, June 13. Canteen Corporation apologizes for any inconvenience.

Call for CRADA proposals

The Technology Transfer Department has issued a call for proposals for Multi-year CRADAs under the Energy Research-Laboratory Technology Transfer (ER-LTT) program. Proposals are due from each division by close of business, Monday, June 20. The ER-LTT projects are expected to be funded starting in October 1994 (FY95).

The ER-LTT Program plans to provide funding of approximately $2 million for new starts at LBL on projects that have potential commercial application. This call is to distribute funds through "Multi-year CRADA" proposals, ranging from $100,000-500,000 per year, for up to 3 years. Approximately 10 new projects are expected to be funded from this call.

There are several changes from past procedures regarding the proposal selection process. The major change is that project selection will occur on site at LBL, rather than in Washington, D.C. To accommodate this new policy, the entire process will be placed on an accelerated time schedule. The goal is to have the projects approved at all levels and actually start work just after the beginning of FY95.

Proposal forms are available in the public folder of Mary Hart on AppleTalk "Dir" zone (filename "Multi-year CRADA Prop"). For a hard copy, call X6462. For more information, call Harry Radousky (X5566), Mary Hart (X6462) or Cheryl Fragiadakis (X7020).

A "brown bag" question-and-answer session about the proposals will be held in the Bldg. 50 auditorium from noon to 1 p.m. on Thursday, June 2.


Remember to mark your calendars for 11 a.m. on Monday, June 6. A reception will be held outside the Advanced Light Source to honor, for their recent awards: LBL Associate Lab Director Glenn Seaborg, Art Rosenfeld of the Energy and Environment Division, Heinz Heinemann of the Materials Sciences Division, and Robert Bergman of the Chemical Sciences Division. All employees are invited to attend.
