Abstract

Plasma-filled rod-pinch diode (PFRPD) is a rod-pinch diode (RPD) filled with plasma that injected across the anode-cathode gap using plasma guns prior to the start of diode current. The injected plasma may reduce the impedance of PFRPD and enhance the dose rate of X-rays. A PIC simulating model of PFRPD is established. The beam pinching situation is described by the axial distribution of electron deposition density (ADEDD) on the anode rod. A PFRPD experiment platform is established, where a 1 MV PFRPD is driven by "Jianguang-I" accelerator low impedance state(1 MV/9 Ω/40 ns). Experiment results indicate that the diode performs better prefilled with appropriate plasma. The diode impedance is reduced to 10 Ω, X ray radiation dose is increased from 0.76 mGy to 3.19 mGy, axial spot is reduced from 9 mm to 4 mm.
