Abstract

The intense epithermal neutron source and boron compounds are needed for Boron Neutron Capture Therapy(BNCT). In 1951, the first clinical study of BNCT was performed at Brookhaven National Laboratory. Over 1000number of clinical studies have been performed in the world. However, some of research reactors have stopped the operation because of the operating life. Kyoto University Research Reactor Institute in Japan and Tsing Hua University in Taiwan are strongly performing the clinical studies of BNCT.<br>The studies about accelerator based neutron source have been promoted in the world from 1980s. However, the actual equipment of accelerator based neutron source did not established because of the lack of the output beam current from accelerator and the issue of target strength. Therefore, Kyoto University Research Reactor Institute and Sumitomo Heavy Industries started the research collaboration about accelerator based neutron source on March 2007. Cyclotron based epithermal neutron source(C-BENS) was successfully established using the reaction between protons with the energy of 30MeV and beryllium target. In this paper, the detail of C-BENS and current status of accelerator based neutron source in Japan are reported.
