“…The 450 kV pulsed X-ray machines for hydrodynamic experiments were used to adopt a commercial reflection-target diode(RTD) with a ceramic enclosure [1][2][3], but the RTD is not good enough because of its small current, low dose, and large ringlike focal spot. In recent years, the rodpinch diode (RPD), similar to the RTD, has been widely used in 1-4 MV flash X-ray machines.…”

This paper proposes a hollow rod as the anode of a rod-pinch diode (RPD) at about 450 kV voltage. Two kinds of hollow rod anodes that may enhance the central radiation dose are obtained through PIC and Monte Carlo simulations. The experimental results show that the hollow anode made by Electrical Discharge Machining (EDM) can effectively enhance the forward central dose of the 450 kV rod-pinch diode, which helps to improve the radiation imaging definition.
