Outline of Final Research Achievements

The Tibet ASgamma collaboration has been pushing forward the underground water Cerenkov Muon Detector (MD) project, in order to improve the sensitivity to cosmic gamma rays. The most stringent upper limit was obtained above 140 TeV on the gamma-ray flux of the Crab Nebula, by means of the data from the 100 m2 prototype MD constructed to confirm the feasibility of the full MD project. The result was published (Amenomori M. et al., 2015, ApJ, 813, 98), and was presented at the conference ICRC2015 (id833, Hague, Holland, 30 July - 6 August). The optimization of the event selection method by means of MD as well as the improvement of the performance of the air-shower array has been under way.
The current status and recent results of the Tibet ASgamma experiment were presented at TeV2015 ( Kashiwa, Japan, 26-30 October) and the conference for cooperative research report at ICRR (18-19, December, 2015).
