ABSTRACT:
A space-discharge electronic device is described, particularly useful as a flash X-ray tube, which device includes a cathode of planar shape and formed with a circular opening therethrough, and a target anode of conical shape and having a pointed tip at the end facing the cathode, the longitudinal axis of the target anode being normal to the plane of the cathode. The pointed tip of the target anode is located in the plane of the planar cathode at the center of its circular opening. When used as a flash X-ray tube, the target anode is made of a material which emits X-rays when impinged by the electrons from the cathode.
