Abstract content
The surface detector of Telescope Array(TA) experiment are deployed in desert of western utah,USA. The detector consists of two layers of plastic scintillators of 3m2 area with wave length shifter fiber(WLSfiber). And at each layer,PMT are connected with WLS fibers. At each layer ,2 LEDs are also equipped to check PMT linearity. To estimate number of shower particles with good accuracy, it is needed toknow the response for 1 minimum ionization particle and the environmental effect on it. PMT linearity are also needed to be monitored and calibrated. Here we report observed variation on detector response and its calibration. And the result of linearity check with LEDs also will be reported.
