A Monte Carlo study to measure the energy spectra of the primary cosmic-ray components at the knee using a new Tibet AS core detector array

摘要：

A new hybrid experiment has been started by AS° experiment at Tibet, China, since August 2011, whichconsists of a low threshold burst-detector-grid (YAC-II, Yangbajing Air shower Core array), the Tibet air-shower array(Tibet-III) and a large underground water Cherenkov muon detector (MD). In this paper, the capability of the measurementof the chemical components (proton, helium and iron) with use of the (Tibet-III+YAC-II) is investigated by means of anextensive Monte Carlo simulation in which the secondary particles are propagated through the (Tibet-III+YAC-II) arrayand an artificial neural network (ANN) method is applied for the primary mass separation. Our simulation shows that thenew installation is powerful to study the chemical compositions, in particular, to obtain the primary energy spectrum ofthe major component at the knee.
