摘要：

XMASS is a multi-purpose detector using a large amount of ultra pure liquid xenon. The properties of liquid xenon, such as large scintillation light yield and high atomic number, are well suited for low energy and low background physics targets, including dark matter, solar neutrinos, and double-beta decay. The XMASS collaboration has recently completed a prototype R&D stage. The primary physics goal of the next-stage XMASS 800kg detector will be a dark matter search. Using self shielding an extremely low background rate of 10(-4)/day/keV/kg and a dark matter sensitivity around 10(-45) cm(2) in cross section may be achieved. Excavation of the experimental hall in Kamioka started in August, 2007. We plan to finish the construction of the detector and being data taking within the next few years.
