A preliminary study on the hollow anode of a 450 kV rod-pinch diode

Abstract

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.
