LBL Currents -- June 3, 1994

Mini-cyclotron barely bigger than a bread box

By Lynn Yarris, LCYarris,@lbl.gov

Responding to the cur-rent fiscal pressure on science to scale back, LBL researchers have developed a cyclotron the size of a microwave oven. Though comparable in size to the early cyclotrons of E.O. Lawrence, this "cyclotrino" is meant not to be used for nuclear physics, but as a tool for measuring trace amounts of elements and their isotopes.

For the past three years, physicist Anthony Young of the Accelerator and Fusion Research Division (AFRD) has led the effort to make a practical, laboratory-sized cyclotron for accelerator-based mass spectrometry. This highly sensitive technique, which can cull and identify single atoms from a sample containing trillions, can be used for a variety of purposes, such as radiodating fossils and archeological artifacts, measuring atmospheric pollutants, sequencing DNA, or studying the metabolism of therapeutic drugs.

Young and his colleagues credit LBL astrophysicist Rich Muller for having launched the modern era of accelerator-based mass spectrometry in 1976 when he developed it as an improvement over radioactive carbon dating.

"We think of Rich Muller as the godfather of our project," Young says. "He was the one who thought to combine mass spectrometry with accelerator technology as a way to make radiodating much more sensitive."

In conventional radiodating, the age of a sample is estimated by taking a count of the one or more carbon-14 atoms that are decaying to nitrogen. In accelerator mass spectrometry, the total number of carbon-14 atoms in the sample are counted whether they are decaying or not. This results in a many thousandfold increase in sensitivity, which means either a much smaller amount of sample is needed, i.e., a tenth of a milligram instead of a gram, or else detection time can be greatly shortened.

Accelerator mass spectrometry as practiced today is remarkably precise but has not been widely adapted because of the size and expense of tandem Van de Graff accelerators, the machines of choice for radiodating samples. (Less than two dozen facilities perform AMS in the world today.)

Muller and his group built a couple of prototypes for a low-energy, relatively inexpensive miniature cyclotron that, like tandem accelerators, were well-suited to measure the presence of carbon-14. Several versions were also built by groups outside LBL. In all cases, however, a variety of technical difficulties hampered development.

"The project became such an engineering tour de force that many people came to believe it couldn't be done," says Young. However, he and his colleagues have made some crucial improvements in their mini-cyclotron that they think will rekindle interest in the technology. Perhaps the most important improvement has been the replacement of an electrical magnet with a series of permanent magnets to generate the cyclotrino's magnetic field. In accelerator mass spectrometry, a sample is vaporized into ions which are then accelerated and sorted according to mass and charge as they pass through a magnetic field. A particle detector is then used to identify the ions. By generating the magnetic field with permanent magnets instead of the electrical magnets used in previous compact cyclotrons, Young and his colleagues have reduced the overall size and weight of their machine and minimized its power and cooling demands.

Permanent magnets also give the cyclotrino a portability that older versions lacked. The team used samarium cobalt magnets designed by Klaus Halbach and Ross Schlueter of the Engineering Division.

The team also improved the injection line that delivers a beam of accelerated ions from its source to the cyclotron's magnetic field. This change improved sensitivity of the cyclotrino.

Sensitivity and detection efficiency were further improved by the use of a negative ion source of the type designed by AFRD's Ka-Ngo Leung for fusion research. With its unique multicusp magnetic field, the negative ion source is not only much easier to operate than the sputter sources used in previous mini-cyclotrons, it also yields a superior quality beam at a much higher current and sample efficiency.

"Our mini-cyclotron is not a competitive technology to conventional accelerator mass spectrometry, but an alternative for those who can't afford to use a tandem accelerator," says Young. "Building a machine like this is something that could not be done at many other places because its design and fabrication called for so many different skills."

Young's collaborators, in addition to those already mentioned, included Kirk Bertsche, a former member of Muller's group, Dave Clark of the Nuclear Science Division, and AFRD's Wulf Kunkel, Chaoyang Li, Mary Stuart, and Russ Wells.

Nuclear scientists pack volumes on single CD

By Mike Wooldridge, MAWooldridge@lbl.gov

Literature searches have just gotten easier for nuclear scientists, and at a price anyone can afford.

Researchers in the Nuclear Science Division's Isotopes Project and at Lund University in Sweden have developed a CD-ROM that holds the bibliographic data for every important paper published on nuclear structure since 1910. Called Papyrus NSR, the compact disk contains the listings found in Nuclear Structure References, the on-line database for low- to medium-energy physics maintained at Brookhaven National Laboratory.

"Papyrus NSR is unique in nuclear physics right now," says LBL physicist Edgardo Browne, who helped spearhead the project. "It is the first bibliographic database of its kind offered on compact disk." Browne worked with Peter Ekström of Lund University to develop the CD-ROM.

Best of all, Papyrus NSR is being distributed free of charge to nuclear scientists through the Isotopes Project, an LBL group that evaluates and disseminates nuclear data to the scientific community.

The new CD-ROM should be particularly valuable to scientists who lack the capability to access the Nuclear Structure References database on-line, such as those working at small universities or at home.

Papyrus NSR will run on most IBM-compatible computers with CD-ROM drives. For efficient performance, Browne recommends users have at least a 386-based system and DOS version 6.2.

The 150 megabytes of data on the Papyrus NSR disk contain more than 130,000 bibliographic references, equivalent to about 10,000 type-written pages. Users can search the references by categories common to most library databases, such as title, author, editor, journal, date and keyword.

To access the reference data, the CD-ROM includes a special version of Papyrus, a bibliographic database program developed by Research Software Design Inc. in Portland, Oregon.

Browne and Ekström plan to offer updates to Papyrus NSR every four months, available over the Internet or on floppy disk. An updated CD-ROM is expected to be released once a year.

For more information about Papyrus NSR, contact Edgardo Browne at X7647.

Gay Pride Month: Events begin with guest speaker

Liz Hendrickson, executive director of the National Center for Lesbian Rights in San Francisco, will begin a lecture series celebrating Gay Pride Month at LBL. Her lecture, "Equality and Inclusiveness: New Landscapes for the 90s" will begin at noon on Thursday, June 9, in the Bldg. 50 Auditorium. Hendrickson will focus on the historical patterns shaping our society's reluctance to embrace true equality, currents obstacles and trends, and implications and hope for the future.

Hendrickson has directed the NCLR, the country's only lesbian rights organization, since 1991. She earned a J.D. from Golden Gate School of Law in 1979 and focused much of her practice on family law and domestic violence. She founded the Alameda County Domestic Violence Law Project in 1982, and headed the free family law services of the Alameda County Bar Association from 1986-1991.

Gay Pride activities designed to address a variety of concerns which may be of interest to the general Lab community have been scheduled for several Thursdays in June. In addition to gays and lesbians, those who are parents, siblings, friends, co-workers, or supervisors of a gay or lesbian person may want to find out more about such issues as acceptance, inclusiveness, openness, privacy, and mutual respect.

Gay Pride Month has been organized by the LBL Lesbian, Gay, and Bisexual Association. Refreshments will be served following the lecture.

In Memoriam--Marianne Larsen

Marianne Larsen, a former LBL Library staff member, died at her home in Richmond on May 29. She worked at the Lab from 1963 until her retirement in October 1993.

Over the course of her career at LBL, Larsen worked on the Magnet (Currents' predecessor), in the Main Library in Bldg. 50, and in each of the various branches.

She is survived by her parents, several siblings, two children--Stephen Larsen and Karen Olson, who works in the Energy and Environment Division--and grandsons Chris, Josh, Cole, and Jesse.

A memorial mass will be held at 11 a.m. on Saturday, June 11, at St. John the Baptist Church on San Pablo Avenue in El Cerrito. In lieu of flowers, the family asks that donations be sent to Sempervirens Fund, Drawer B, Los Altos, CA 94023.

Warehouse relocation process underway

The relocation of the off-site Warehouse and Receiving Facility has begun, and the month-long process of moving the entire Receiving and Excess Property function along with more than 2,000 storage items will continue until June 20.

The new facility is located at 2700 Seventh Street in Berkeley and will have the designation Building 903. Central Receiving, Bulk Storage, Bulk Issue, and Used Furniture will also be relocated there.

Building 903 will offer high levels of both security and communication, and will feature a new AT&T partnership telephone system with an LBL Net T-1 upgrade for the new ORACLE purchasing system.

NSD HOSTS IAEA MEETING:

The Isotopes Project in the Nuclear Science Division hosted the 11th International Atomic Energy Agency Advisory Group Meeting on the Coordination of the Nuclear Structure and Decay Data Evaluators' Network. This biennial meeting, held at LBL May 16-20, was attended by 40 nuclear physicists from 14 countries. It was the first time the meeting had been held in the United States since 1977. The meeting agenda focused on future planning and how to provide for the evolving data needs of researchers as research priorities change. A record number of action items will determine the work carried out by the centers during the next two years. During the week, the group also enjoyed a trip to Napa Valley and a banquet at the California Culinary Academy. Local organizers of the meeting were Janis Dairiki and Rick Firestone of LBL, and Craig Stone of San Jose State University.

LBL PEOPLE:

Alexis T. Bell of LBL's Materials Sciences Division has been appointed dean of UC Berkeley's College of Chemistry, effective July 1. He has served as acting dean since April, when C. Bradley Moore, a researcher in LBL's Chemical Sciences Division, stepped down from the position to return to teaching and research.

EH&S training made easy for summer students

With summer nearly upon us, most divisions are expecting the arrival of summer students. These students will need EH&S information and training in order to work safely and to maintain compliance with regulations and DOE Orders. The EH&S Training Unit has coordinated this summer's training schedule so the students will be able to attend timely and relevant training.

Until they receive training appropriate to the hazards to which they may be exposed at LBL, students may only work under continuous, direct supervision. It is the supervisor's responsibility to ensure that students receive training. At a minimum, all students who will be working for more than one month must take "Introduction to Environment, Health, and Safety at LBL" (EHS-10, EHS-392, and EHS-405).
