In this paper is given briefly a survey of situation of simulating pulsed x-ray with high current pulsed electron beam accelerator. It´s indicated that technology of high pulsed power Z-pinch has vast application prospects in the realization of ultraintensive pulsed x-ray simulator and ICF driver as a chief technological way. Also are described the progress and the current status of simulators for pulsed x-ray in China, and proposals for the future development of Z-pinch technology.
