Abstract
Due to large variation of particle density in EAS, a response linearity of each detector needs to be assessed. The number of photon in a photo multiplier tube (PMT) pulse allows inferring the deviation from linearity in each case. In order to obtain an approximate photon count of a pulse, a single photo-electron response pulse calibration for the R7723 PMT was conducted using low-level light pulse. Non-linearity measurements of PMT were conducted using the same setup. PMT signals were chosen such that their widths are comparable with the real data. Results included in this work show that the PMT signal is mostly linear and nonlinearity starts only at the upper end of ADC range.
