Abstract
We develop a traveling wave gated X-ray framing camera based on electron beam pulse-dilation technology. The photocathode is loaded with a direct current (DC) bias of -3 kV and a widening pulse with a slope of 2.7 V/ps, and the microchannel plate biased at -483 V superimposed a negative high voltage gated pulse with full width at half maximum (FWHM) of 290 ps. The imaging ratio of the camera is 1∶1. Laser acts on a gold target to generate X-rays for uniform irradiation on the cathode. The temporal resolution of the camera is 20 ps and the gain uniformity of 20 mm cathode strip is better than 20%. The measured value of spatial resolution through a DC ultraviolet light source is 10 lp/mm in the range of imaging surface with a diameter of 56 mm.
