Self-limiting x-ray tube with flat cathode and stair-step focusing device |
摘要 |
Problems of thermal resistance of the anode of an x-ray tube are solved by constructing a flat cathode which is set within a stair-step focusing device. It is shown that, depending on the shape of this device, the heat output on the anode is limited by a saturation value which is lower than a limit of thermal resistance of the x-ray tube. In order to improve the thermal resistance of the cathode, a cathode is constructed in the form of a hollow beam. This ensures rigidity of the cathode which is inherent in its beam shape without being attended by the disadvantages of excessive thermal inertia.
