Progress report on the MD-A under TIBET III array

Abstract:

The underground muon detector array of 4500m2(5 modules) is constructed underneath the Tibet ASγ experiment, improving the γ/P separation ability and then the sensitivity for gamma ray observation around 100 TeV. Each module of the muon detector is a large water tank with PMTs in the center, using water Cherenkov technique to obtain the muon signal. In one module (MD-A), the large Tyvek bag is employed filled with high-purity water keeping long-term stability of the water quality. The test run data of MD-A have shown the detector has good position uniformity, and the muon signal can be clearly separated from the noises. In this paper, the design and performance of the detector are presented.
