A compact flash radiography accelerator based on fast linear transformer driver(FLTD) and rod-pinch diode(RPD) becomes the research hotspot. A PIC model of the 40-stage FLTD driven RPD was built. The output characteristics of positive and negative polarity of magnetically insulated transmission line(MITL) inner electrode were compared and analyzed, and the properties of electron beam pinch for RPD at the diode voltage of 4 MV was simulated. Simulation results show that the effective electron current proportion in positive polarity MITL was lower than that in negative polarity MITL under the same condition. Under the diode voltage of 4 MV, the electron beam of RPD was pinched well and the electron beam distribution is concentrated in axial direction, and about 38% electrons hit 1.5 mm area around the needle point of the rod.
