Two Brookhaven Lab Scientists Honored For Their Contributions to Physics

Upton, NY -Two scientists at the U.S. Department of Energy's Brookhaven National Laboratory were honored recently for their contributions to particle-accelerator physics: Ilan Ben-Zvi and Alessandro Ruggiero.

To recognize his outstanding contributions to the development of particle-accelerator science, Dr. Ben-Zvi, a senior physicist who is the head of Brookhaven Lab's Accelerator Test Facility and deputy head of Brookhaven's Center for Accelerator Physics, was awarded a 1999 Particle Accelerator Science & Technology Award. Sponsored by the Nuclear & Plasma Sciences Society of the Institute of Electrical & Electronics Engineers, Inc., the award consists of $2,000 and a plaque, which cited Dr. Ben-Zvi: "For contributions to high-brightness electron beam technology and superconducting rf technology, and for his leadership of Brookhaven National Laboratory's Accelerator Test Facility.

Physicists from around the world use Brookhaven's Accelerator Test Facility to research new methods of accelerating high-brightness electron beams and novel ways of producing intense short-wavelength electromagnetic radiation. Such research may lead to more powerful, yet compact, accelerators, and better synchrotron light sources, facilities that use x-rays, infrared radiation and ultraviolet radiation to study materials at the atomic level. These investigations may lead to such advances as better computer chips or new drug design.

After receiving his Ph.D. in physics from the Weizmann Institute of Science, Israel, in 1970, Dr. Ben-Zvi went to Stanford University, where he helped develop the earliest stages of superconducting linear accelerators. In 1975, he returned to Weizmann, where he founded a cryogenic technology laboratory. As a visiting associate professor of physics at the State University of New York (SUNY) at Stony Brook, 1980-82, Dr. Ben-Zvi helped to establish an accelerator at the school, inventing and developing systems now used throughout the world.

After working on accelerators in Europe and the U.S., Dr. Ben-Zvi came to Brookhaven as a visiting scientist in 1988. In March 1989, he joined Brookhaven as a physicist. He is an adjunct professor of physics at SUNY Stony Brook and a Fellow of the American Physical Society (APS). Most recently, he was elected an officer of the executive committee of the APS Division of Physics of Beam. He is on the editorial board of Physical Review Special Topics - Accelerators and Beams, and he has authored or coauthored over 140 publications.

Alessandro Ruggiero, a senior scientist at Brookhaven, was named a Fellow of the APS. Formed in 1899, the 41,000-member APS is dedicated to advancing physics and spreading knowledge and information about its fields. Election as an APS Fellow is peer recognition of outstanding contributions to physics through original research and publication, significant and innovative applications of physics to science and technology, and/or physics teaching or service to society. No more than one-half percent of the society's members are elected Fellows.

Nominated by the APS Physics of Beam Division, Dr. Ruggiero was cited: "For contributions to accelerator theory, including instabilities and nonlinear dynamics; to accelerator complex designs, notably the Antiproton Source and the Relativisitic Heavy Ion Collider; and to accelerator architecture investigation of Spallation Neutron Sources."

The Anitproton Source, located at Fermilab in Chicago, and the Relativistic Heavy Ion Collider, which has been built at Brookhaven Lab and is scheduled to start operating this year, are basic physics research facilities funded by the U.S. Department of Energy. Spallation Neutron Sources provide scientists with beams of neutrons to conduct experiments that have led to the design of better materials and products used in everyday life.

After Dr. Ruggiero earned his Ph.D. in physics from the University of Rome in 1964, he worked at several physics facilities in Europe. In 1970, he came to the U.S. and worked as a physicist at Fermilab until 1987, when he joined Brookhaven Lab's staff as a senior physicist in the Accelerator Physics Division, which he headed for several years. He currently works in the Laboratory's Alternating Gradient Synchrotron Department.

Dr. Ruggiero is a member of the New York Academy of Sciences and has authored or coauthored close to 300 publications.
