Marshall Rosenbluth.

Marshall Nicholas Rosenbluth (born February 5, 1927 in Albany , † September 28, 2003 in San Diego ) was an American physicist who had a leading position in theoretical plasma physics .

Live and act

Rosenbluth studied at Harvard University , but served as a volunteer in the US Navy from 1944 onwards. After retiring from the military, he completed his studies in 1946. In 1949 Rosenbluth received his doctorate from the University of Chicago on a topic from high energy physics, his doctoral supervisor was Edward Teller . In 1949/50 he was in Stanford , where he developed the Rosenbluth formula for the elastic scattering of electrons on protons.

From 1950 to 1956 Rosenbluth worked under the direction of Edward Teller in the Los Alamos National Laboratory in the hydrogen bomb . In 1953 he was involved in the development of the Metropolis algorithm as a prototype of a Monte Carlo method , as was his wife Arianna W. Rosenbluth .

Since 1956 Rosenbluth dealt with plasma physics. He first worked at General Atomics in San Diego . In 1960 he became professor of plasma physics at the newly founded University of San Diego . In 1965 he led an international workshop for plasma theory with the Russian Roald Sagdeev at the ICTP in Trieste , which was particularly important for the contacts between Russian and American scientists. In 1967 he moved to Princeton, where he conducted research at the Institute for Advanced Study and the Princeton Plasma Physics Laboratory and taught at Princeton University . From 1980 to 1987 he was director of the Institute for Fusion Studies at the University of Texas at Austin . He then returned to General Atomics and the University of San Diego, where he remained until his retirement in 1993. After retiring, he was chief scientist in the ITER planning team until 1999 .

Rosenbluth studied plasma instabilities in particular and became a leading theorist in the field. He also dealt with the theory of the free-electron laser .

Rosenbluth was married twice and had four children from his first marriage. He died of pancreatic cancer in 2003 .

Honors

Rosenbluth was a fellow of the American Physical Society since 1959 , of the American Academy of Arts and Sciences since 1966, of the National Academy of Sciences since 1969 and of the American Philosophical Society since 1998 . He also sat on the Department of Energy's Fusion Energy Special Advisory Committee and was a member of the JASON Defense Advisory Group .
