Abstract: In order to meet the requirements of photon-electron simulations in the practical applications, the photon-electron coupled transport function is researched and developed in JMCT. This function is realized in several different ways so as to satisfy a variety of engineering requirements. Typical photon-electron coupled transport examples are simulated, which verifies the correctness of JMCT photon-electron coupled function. In addition, this function is applied to simulate the detector response functions and flash radiography. It is shown that JMCT will play a more and more important role in the field of experimental nuclear physics and nuclear analysis technology.
