...SHIZUE HINOKAWA ABSTRACT: This article describes the process of cyclotron development in Britain in the 1930s by focusing on the relationships between John D. Cockcroft, James Chadwick, and the Metropolitan-Vickers Electrical Company, Ltd. There is a difference of about one year in the completion...

... Nobel prize winners in physics but also raised the level of Japanese physics overall. Among Nishina's many contributions to the Japanese physics community, the construction and operation of two cyclotrons during the 1930s and 1940s were the most celebrated. In this paper I try to answer the following...

...MORRIS F. LOW ABSTRACT The destruction of Japan's cyclotrons by Occupation Forces after the Pacific War resulted in a major setback for experimental physics in that country. Key figures such as Yoshio Nishina, Sin-itirôô Tomonaga, and Ryôôkichi Sagane strived to help Japan rebuild its scientific...
