Abstract
A cooling device for microwave tubes includes a cold part and a heat-conducting member having a first surface in contact with a surface of the cold part. A second surface of the heat-conducting member is in contact with an envelope of the tube. The surface of the cold part and the first surface of the heat-conducting member are respectively concave and convex. The device can be applied to the cooling of microwave tubes including klystrons, travelling-wave tubes and gyrotrons.
