Abstract :
The axial spot size of a rod-pinch diode (RPD) has a significant effect on the spatial resolution of the radiographic system, when the RPD is used as an X-ray source for pulsed radiography. The simulation and experiment results indicate that a compound cathode can be used to reduce the axial spot size.
