Description
The XMASS project aims at detecting dark matter, pp and 7Be solar neutrinos,
and neutrino less double beta decay using large volume of pure liquid xenon.
The first physics target of the XMASS project is to detect dark matter
with 835kg liquid xenon. After the commissioning runs, XMASS detector was
refurbished to minimize the background contribution mainly from PMT sealing
material and we restarted data taking in November 2013. Surface purity control
during XMASS detector refurbishment and the result is reported.
Status and future plan of XMASS are also reported.
