Rubby Sherr

Rubby Sherr (born September 14, 1913 in Long Branch (New Jersey) , † July 8, 2013 in Haverford (Pennsylvania) ) was an American physicist who studied nuclear physics and was involved in the development of the atomic bomb .

Career

Sherr was born the son of Lithuanian immigrants, attended Lakewood High School and New York University . He made there in 1934 a bachelor's degree in physics and Princeton University in 1938 a doctorate in physics. In 1942 Sherr moved to the Massachusetts Institute of Technology . From 1944 he worked for the Manhattan project to build the first atomic bomb in a group led by Charles Critchfield . Together with Klaus Fuchs, Sherr developed an important element for the detonator of the plutonium bomb, the Fuchs-Sherr modulated neutron initiator , a neutron source in the center of the bomb. In 1945, he observed the dropping of the first atomic bomb from a bunker.

From 1946 Sherr was professor at Princeton University, from 1949 Associate Professor and since 1955 with a full professorship. In 1953 he found experimental evidence of the Fermi interaction . From 1955 to 1971 he headed a project for the United States Atomic Energy Commission . He conducted research on nuclear physics at low energies at the Princeton cyclotron, whose development into the Princeton AVF cyclotron (1970) he oversaw. Sherr retired in 1982. Most recently, he worked on the calculation of properties of mirror cores .

Over the course of his life, Sherr has published over 100 scientific papers. In 1947 he invented a scintillation counter and in 1953 a Doppler radar .
