Klaus Halbach

from Wikipedia, the free encyclopedia

Klaus Halbach (born February 3, 1925 in what is now Wuppertal ; † May 11, 2000 ) was a German physicist who dealt with the physics of particle accelerators .

Life

Halbach received his doctorate in 1954 at the University of Basel on a new method for measuring relaxation times and on the spin of Cr53 and then taught for three years at the University of Friborg . In 1957 he went to the USA to join Felix Bloch at Stanford University . After a short stopover in Switzerland, he returned to the USA in 1960, where he studied plasma physics at the University of California, Berkeley . There he turned to accelerator physics, initially in the development of the concept of the Omnitron synchrotron accelerator for nuclei, which was never built (however, the development was incorporated into that of the heavy ion accelerator at LBNL Bevalac ). He was a long-time scientist at the Lawrence Berkeley National Laboratory (LBNL). In 1991 he officially retired there.

Halbach was known as a specialist in the development of magnet systems for accelerators (especially wigglers and undulators for synchrotron radiation sources and free electron lasers ). The Halbach array (1980) comes from him . He and his future son-in-law Holsinger wrote the much-used Poisson code for the design of magnetic systems. Halbach was a consultant in the development of the storage ring for the Advanced Light Source in Berkeley, the Stanford Synchrotron Radiation Laboratory (SSRL) and the Advanced Photon Source of the Argonne National Laboratory .

He also developed miniature magnets for NMR spectrometers , which should be used for future space missions to Mars, and for small cyclotrons for isotope separation in medicine. He was also involved in the development of magnet systems for high-resolution spectrometers at the Jülich nuclear research facility and at LAMPF in Los Alamos.

Awards

Halbach received the Arthur H. Compton Prize. In 1990 he became a Fellow of the American Physical Society .
