Abstract
Aiming at the observation of cosmic-ray chemical composition at the knee energy region, a new type airshower- core detector (YAC, Yangbajing Air shower Core array) has been developed and set up at Yangbajing, 4300 m a.s.l. in Tibet, China since August, 1st, 2011. YAC will work together with the Tibet-III array and a large muon detector as a hybrid experiment. Each YAC detector unit consists of lead plates 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. The burst size is demanded to be measured from 1 MIP (Minimum Ionization Particles) to 106 MIPs. The linearity and the saturation of the plastic scintillator and PMT used in the YAC detector have been studied with the accelerator beam of the BEPCII (Beijing Electron Positron Collider, IHEP, China). The accelerator-beam experiment shows a good linearity between the incident particle flux and YAC-ADC output below 5×106 MIPs and the saturation effect of the plastic scintillator satisfies YAC detector's requirement.
