Outline of Final Research Achievements

Liquid is widely used as an ultra-low background and threshold experiments for example dark matter search. This study aimed at the removal of radioactive radon from xenon, in order to achieve further low background environment in liquid xenon detector. The development of the low background radon detector and radon removal test were carried out in order that. As a result, the radon detector has succeeded to reduce the background approximately 1/10. In addition, the development of heat exchange mechanism for the circulation of the low temperature of xenon was carried out Even that the material did not be found for radon adsorbent alternative to activated carbon, it make the prospect of the way for the development of more efficient radon removal system.
