NUMERICAL SIMULATION OF REEMISSION DELAY TIME OF Au DISK HEATED BY X-RAYS

One dimensional multi-group radiation transport program is used to simulate the process of X-rays heating Au disk. The reemission delay times of Au disk vs X rays photon energy were given and compared with recent experimental results. It is found that the theoretical results fitted well with the experimental results, especially the trend of reemission delay time. This proved that the one dimensional multigroup radiation transport program can do well in simulating the experimental process of X rays heating Au disk．
