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.
Claims7
A space-discharge electronic tube including a cathode and a target anode, characterized in that said cathode consists of a single planar electrode formed with a circular opening therethrough, and that said target anode is of conical shape and has a pointed tip at the end thereof facing said planar cathode electrode, the longitudinal axis of the target anode being normal to the plane of said planar cathode electrode and the pointed tip of the target anode being located in the plane of said planar cathode electrode at the center of its circular opening.
