Abstract

We have operated the 500 m2 Yangbajing air-shower core (YAC-II) detector array near the center of the Tibet air-shower array ( Tibet-III ) to study the cosmic-ray chemical composition at the knee energy region since August, 2011. YAC-II array consists of 124 YAC detector units. Each unit of YAC-II consists of a lead layer of 3.5 cm thick and a scintillation counter which detects the burst size induced by high energy electromagnetic component in the air-shower cores. Each scintillator has the size 80 cm × 50 cm × 1 cm. 60 WLSFs (Wave Length Shifting Fiber) are installed inside the scintillator, a high-gain PMT and a low-gain PMT are coupled with it. The burst size can be measured from 1 MIP (Minimum Ionization Particles) to 106 MIPs. In this paper, the details of the hybrid experiment and the processes of the data reconstruction are described.
