Renate Chasman

from Wikipedia, the free encyclopedia

Renate Wiener Chasman , née Wiener, (born January 10, 1932 in Berlin ; † October 17, 1977 ) was a German-American physicist who studied the physics of particle accelerators .

Chasman was the daughter of Hans Wiener, a lawyer and founding member of the Social Democrats. The family, who were Jewish, fled to Sweden in 1938, where Chasman attended school near Stockholm. After graduating from high school in 1950, she went to Israel to study physics at the Hebrew University in Jerusalem . In 1955 she completed her master's degree there and in 1959 she received her doctorate in experimental physics with work on parity violation in beta decay (there Wiener coefficients are named after her). As a result of this work, she was transferred from Chien-Shiung Wu (who experimentally discovered the parity violation in beta decay) to Columbia Universityinvited, where Chasman researched in Wu's laboratory from 1959 to 1962. She then went to Yale University and from 1963 to Brookhaven National Laboratory , where she stayed for the rest of her career. At Brookhaven Laboratory, she made important contributions to the development of several generations of particle accelerators. In the 1960s she rebuilt the injector for the Alternating Gradient Proton Synchrotron (AGS) and thus higher energies were achieved with the accelerator. Among other things, she is known with Kenneth Green for the Chasman-Green arrangement ( Chasman Green Lattice or Double bend achromatic lattice , DBA lattice) of magnets for focusing and deflecting electron beams in synchrotron radiation sources (1975). It was used at the National Synchrotron Light Source at the Brookhaven Laboratory and thereafter on most synchrotron radiation sources with electron accelerators.

She was also a consultant and visiting scholar at CERN and Fermilab . She died of complications from skin cancer ( melanoma ).

Since 1962 she was married to Chellis Chasman.
