JMCT simulation of response functions for gamma-ray detectors

The JMCT software is used to calculate the gamma-ray response functions for NaI crystal. The complete process of all the photon-electron coupled transportation is simulated by JMCT. The gamma-ray energy deposition spectrum and detector response functions are obtained and discussed. It is found that the results calculated by JMCT are the same as the results calculated by MCNP, and correspond well to the results calculated by Berger, which shows that the detector response functions simulated by JMCT are correct and satisfying. JMCT will play a more and more important role in the field of the experimental nuclear physics and nuclear analysis technology.
