Bruno Rossi
Bruno Benedetto Rossi (born April 13, 1905 in Venice , † November 21, 1993 in Cambridge , Massachusetts ) was an Italian astrophysicist and elementary particle physicist .
Life
Rossi received his doctorate at the University of Bologna and was from 1928 assistant at the University of Florence . In 1932 he became a professor of experimental physics at the University of Padua . As a Jew, he lost his professorship in 1938 and went to the USA via Copenhagen and Manchester , where he was a visiting scholar at the University of Chicago in 1939 . In 1942 he became an associate professor at Cornell University . During World War II, he worked on radar development at the Massachusetts Institute of Technology (MIT) Radiation Lab and later on the nuclear weapons program in Los Alamos (he co-led the detector development group). In 1946 he became a professor at MIT, where he again studied cosmic rays and in the late 1950s was a pioneer of rocket experiments, e.g. B. to measure the interplanetary plasma and (as a consultant to American Science and Engineering Inc.) discovered the first X-ray source outside the solar system (Scorpio X-1). In 1965 he became an institute professor at MIT. In 1970 he retired there and taught at the University of Palermo from 1974 to 1980 . Kenneth Greisen is one of his PhD students .

Bruno Rossi was a pioneer in the research of cosmic rays in the 1930s and was one of the first to detect cosmic X-rays with rocket experiments .
In 1939 he was the first to demonstrate the decay of the muon at the University of Chicago and measured (at Cornell University) its mean lifespan.
Rossi also developed a number of electronic techniques in experimental physics, e.g. B. 1930 circuits for coincidence observation, 1942 the " Time to Amplitude Converter " and 1943 in Los Alamos with Hans H. Staub the "Fast Ionization Chamber".
