Abstract

Abstract

A pulsed X-ray radiographic source based on inductive voltage adder (IVA) and rod-pinch diode (RPD) is developed at the Northwest Institute of Nuclear Technology. The X-ray spot size of RPD is a critical parameter to evaluate the spatial resolution performance for radiography. Using thick pinhole imaging technique, two-dimension images of the RPD X-ray spots have been measured. A pinhole with 0.2-mm-diameter was designed and an image acquirement system based on a lutetium-oxyorthosilicate-crystal scintillator, a lens and a CCD camera was established. The magnifications of the pinhole and the lens are about 5 and 0.34, respectively. The spatial resolution of the pinhole imaging layout is 2.0 lp·mm-1 at the modulation transfer function (MTF) of 0.5 for 0.5 MeV X-ray. Through the restoration
