Description
The China JinPing underground Laboratory (CJPL) is the deepest underground laboratory in
operation in the world. It is located under the Jinping mountain, in the southwestern Chinese
province of Sichuan. The experimental hall has an overburden of about 2400 m of rock. The
measured muon flux in CJPL is around 60 muons per squaremeter per year. This extremely
small muon flux make CJPL a perfect place to host low background experiments looking
for really rare events like neutrino less double beta decay (0nuBB decay) or dark matter (DM)
interactions. Since Ge76 can decay via double beta decay, several 0nuBB decay experiments used
and use Germanium detectors (e.g. Heidelberg-Moscow, GERDA and Majorana). These fulfill
also many experimental requirements for DM search, indeed numerous DM experiments use
this technology (e.g. CDMS, Edelweiss and CDEX). The idea is to combine these two searches
in a unique one Ton Germanium facility placed in CJPL. The sensitivity achievable was investigated.
Research on detector development is performed at the Max-Planck-Institute for Physics in
Munich. The goal is to use the same detector for both searches. Some results on events due to
contaminations on the detector surfaces are also presented.
