英文摘要A gamma/hadron separation analysis is described for the observed air shower events with primary energy above 100 TeV based on the Tibet AS gamma detector configuration. The shower age and size parameters are fitted from the measured lateral density distribution and used as discrimination variables. According to the MC simulation while taking into account the systematic uncertainty estimated from data and MC comparison, it is found that 70% of the cosmic ray (CR.) background can be rejected while more than 78% of the gamma-rays can be retained. Sensitivity for 100 TeV gamma-rays observation can thus be improved by at least 40%.
