Description
The XMASS 800kg liquid xenon detector is under construction in the Kamioka mine in Japan. Designed as a multi-purpose underground detector, its physics reaches include
dark matter, solar neutrino and neutrinoless double beta decay, etc. The current detector is optimized for the search of WIMP dark matter candidates. The background event rate is expected to be as low as 1e-4 count/day/kg/keVee. The construction of the PMT array, xenon and water circulation system, electronics, etc. is reviewed, and the performance of PMTs, xenon circulation and purification system and the DAQ system is summarized in order to show how the designed background level is approached.
