Outline of Final Research Achievements

Compact, light weight and portable radiotherapy source was developed. This source generates fast neutron by fusion neutron from DD glow discharge, and optimized moderator combination forms required optics, energy and dose rate of neutron beam. Numerical modeling was performed to optimize the design. Low dose rate neutron can used to irradiate tumors to accumulate sufficient fluence to selectively damage cancer cells while keeping radiological effects to normal cells minimal. Approximately twice a day of radiotherapy for 3 months are expected to be sufficient, and be applicable for many of the medical facilities.
