Abstract
An x-ray tube includes a center shaft having an inner surface and an outer surface, the inner surface forming a portion of a cavity therein, a mount having an inner surface, the mount having an x-ray target attached thereto, and a liquid metal positioned between the outer surface of the center shaft and the inner surface of the mount. The x-ray tube further includes a flow diverter positioned in the cavity, the flow diverter having a wall with an inner surface, and a plurality of jets passing through the wall, wherein the plurality of jets are configured such that when a fluid is flowed into the flow diverter and passes along its inner surface, a portion of the fluid passes through the plurality of jets and is directed toward the inner surface of the center shaft.
