Title:
【発明の名称】飽和により電子束を自動的に制限するX線管
Document Type and Number:
Japanese Patent JP2840615
Kind Code:
B2
Abstract:
The problems are resolved of temperature holding of an anode by making a flat cathode (1) engraved in a device (8) for running focusing. It is shown that, depending on the shape of this device, the heat flow at the anode is limited by a saturation value lower than a thermal holding limit for this tube. In order to improve the thermal holding of the cathode, a hollow beam-shaped cathode is made. This ensures it a rigidity inherent in its beam-shape without however enclosing it with the disadvantages of too large a thermal inertia.
