Abstract
In the study of hadronic interaction in the forward region by the simulation of cosmic ray, it is necessary to simulate large numbers of cosmic ray events with low first interaction height. We confirmed that by reducing the FIXCHI the efficiency of cosmic ray simulation can be improved. But the calibration for energy slope is needed. We got the energy slope based on the probability of direct arrived events with energy of 1 TeV, and fitted the intensity of spectrum with energy to make certain the energy slope of high energy cosmic ray. By this way, the efficiency and precision of cosmic ray simulation is greatly improved.
