Yuri Dmitrievich Prokoschkin
Yuri Dmitrijewitsch Prokoschkin ( Russian Юрий Дмитриевич Прокошкин ; born December 19, 1929 in Moscow ; † March 1, 1997 ibid) was a Russian elementary particle physicist and university professor .
Life
Prokoschkin, son of the materials scientist Dmitri Antonowitsch Prokoschkin , studied at the physical and technical faculty of the Lomonosov University in Moscow , graduating in 1952. In 1951, while still a student, he entered the laboratory No. 2 for measuring instruments of the Academy of Sciences of the USSR (AN-SSSR) (later the Kurchatov Institute ) as an intern at MS Kosodajew . In 1953, on IV Kurchakov's initiative, Kosodajew's group with Prokoschkin moved to Dubna in the Laboratory for Core Problems of the United Institute for Nuclear Research . There Prokoschkin began his work at the local protons - synchrocyclotron . He defended his candidate dissertation on the formation of the neutral pion through proton-proton reactions so successfully in 1961 that the official opponents AM Baldin and IJ Pomerantschuk immediately earned their doctorate in physical-mathematical sciences together with B. Pontecorvo Prokoschkin . In 1962, Prokoschkin's group observed the first beta decays of the pion according to the weak interaction theory . Later, Carlo Rubbia's group at CERN also investigated the pion decay.
In 1963 Prokoschkin became head of the department for experimental physics in the Institute for High Energy Physics in Protvino . He created the experimental basis for the institute's research work and designed the research program for the largest particle accelerator at the time with 70 giga-electron volts . He further investigated the pion decay and determined the probability of decay. In 1965 Prokoschkin received the Kurchatov gold medal for experimental evidence of the beta decay of the pion . Under his leadership, new experimental facilities for on-line investigations as well as Cherenkov radiation spectrometers and scintillators were developed. Despite the difficulties caused by the Cold War in the 1960s, Prokoschkin managed to collaborate with CERN and scientists in Belgium , France , Japan and the USA . The large spectrometers developed were used in the search for exotic mesons and were also used at CERN. Prokoschkin's particle registration system was also used in CERN, Fermilab and Brookhaven National Laboratory .
In 1970 Prokoschkin became a corresponding member of the AN-SSSR. Prokoschkin was awarded the Lenin Prize in 1986 for proof of scale invariance . In 1990 he became Professor and Actual Member of the AN-SSSR, which in 1991 became the Russian Academy of Sciences (RAN). He was also a member of the Academia Europaea . He was for many years with editor of the Russian magazine Physics of Atomic Nuclei and Uspekhi Fizicheskikh Nauk / Physics-Uspekhi .
In his last years Prokoschkin examined the possibilities for the use of lead tungstate - single crystals for a calorimeter in the Compact Muon Solenoid at the Large Hadron Collider at CERN.
Prokoschkin died of cancer . His grave is in the Trojekurovo cemetery in Moscow .
