Air-shower core detector array to study the mass composition of cosmic rays beyond 100 TeV by Tibet hybrid experiment

Abstract:

New air-shower core detector YAC has been developed to measure cosmic-ray mass composition around the energy region of the knee. Prototype experiment YAC1 was successfully carried out in 2009-2010 together with Tibet III air-shower array. Enlarged installation YAC2 is also under construction and will be operated in fall 2011. Preliminary result of YAC1 and performance of YAC2 are presented in this paper. The test of interaction models currently used in air-shower simulation was made using YAC1 results. Burst size flux pbkp_redicted by QGSJET2 and SIBYLL models are compatible with data of YAC1 while QGSJET1 pbkp_redicts 20 % lower flux and EPOS does 30 % lower flux. Proton flux was derived from YAC1 data based on QGSJET2 model and it is smoothly connected with direct observation data at lower energies and also with previously reported our works at higher energies.
