| Research Abstract |
One of the aims of this research project is to collect historical materials that were possessed by Shiryo-chosa-kai, an agent that was established by retired Navy's personnel after the Second World War. Among the materials, Toshin-shiryo, progress reports of the Navy Institute of Technical Research, and Kenkyu-shiryo, research reports there, are essentially important as the basic documents to study historical process of radar and nuclear research of the Japanese Navy before and during the war. We have made microfilm copy of these materials.
Other materials we collected are research reports of F-research, Navy's nuclear project that was headed by Bunsaku Arakatsu, an experimental physicist at Kyoto Imperial University, and progress reports of Ni-research, the Japanese Army's nuclear weapon project, by Yoshio Nishina, an experimental physicist at Riken, the Institute of chemical and Physical Research.
The critical mass problem in both the Army and the Navy were studied in detail, and we found that the notion of Nishina's atomic bomb was a nuclear reactor out of control. The historical development of Japanese radar was studied using the above materials.
