His many achievements include participation in the first demonstration of phase stability, the development of the first synchrocyclotron and the first sector-focused cyclotron.〔Craddock, M. K., and D. J. Clark. (1999)〕 Richardson grew up in Vancouver until his family immigrated to the USA in 1922. He studied physics at UCLA and was a doctoral student in nuclear physics of Ernest Orlando Lawrence at the University of California, Berkeley, receiving his PhD in 1937. After a year at the University of Michigan, he became Assistant Professor at the University of Illinois. From 1942 he worked on electromagnetic isotope separation for the Manhattan Project in Berkeley and Oak Ridge (calutron). In 1946, after the discovery of the phase stability and the synchrotron principle by Weksler and Edwin McMillan, he collaborated with a group of physicists consisting of Ed Lofgren, Ken MacKenzie, Bernard Peters, Fred Schmidt and Byron Wright in converting the fixed-frequency 37-inch cyclotron at Berkeley to the first synchrocyclotron. This success not only provided the first demonstration of the phase-stability principle but also confirmed the feasibility of converting the large Berkeley 184 inch cyclotron from a classical cyclotron to a synchrocyclotron.〔Calisphere: In Memorandum〕 An even bigger sector cyclotron with energies up to 520 MeV was built by Richardsons line at TRIUMF in Vancouver. From 1971 to 1976, Richardson was the director of the laboratory, where he oversaw the construction of the cyclotron. In 1991 he received the Robert R. Wilson Prize.〔Wilson Prize Recipient〕 ==Notes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Reginald Richardson」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
