Gersh Itskovich Budker (born May 1, 1918, Murafa, near Vinnitsa, Ukraine—died July 4, 1977, Novosibirsk, Russia, U.S.S.R.) Soviet physicist who developed new methods of particle acceleration in high-energy physics.
Budker graduated from Moscow State University in 1941 and served in air defense during World War II. In 1945 he started working in Laboratory #2 (subsequently renamed the Kurchatov Institute of Atomic Energy) in Moscow on the theory of nuclear reactions; he received a doctorate for this work in 1950. After taking part in the construction of a proton accelerator in Dubna, Budker shifted his research to relativistic plasma physics. In 1952 he proposed the idea of a stabilized electron beam and also suggested plasma traps with magnetic mirrors for controlling nuclear fusion. In 1958 Budker organized—and directed until his death—the Nuclear Physics Institute in Akademgorodok (near Novosibirsk) as part of the new Siberian branch of the U.S.S.R. Academy of Sciences. From 1965 to 1967, he constructed electron and electron-positron accelerators based on a new method of colliding beams, and in 1966 he invented a method of using electrons to cool (slow) heavier particles. Budker was elected a corresponding member (1958) and a full member (1964) of the Academy of Sciences.
