Description

ABSTRACT:
An X-ray tube with a rotating, motor-driven anode made up from a disc of graphite covered on a major portion of its convex surface which is turned away from its axis of rotation by a layer of an X-ray emissive refractory metal or alloy which has a much lower coefficient of thermal emissivity than the other face of graphite. To reduce thermal radiation in the direction of the rotor to which the anode is secured, the X-ray emissive, convex, covered surface of the anode, which is subjected to electron bombardment, is turned toward the rotor and the cathode lies on the same side of the anode as the rotor of the driving motor, resulting in reduced operational temperatures of these parts. Additional thermal protection for the rotor and bearing is afforded by providing a reflective surface on the rotor or by installing a protective disc-shaped shield between the rotor and the anode. The reduced temperatures of rotor and bearing permit increased output power and lengthened operating periods of the X-ray tube. In addition, a coolant may be circulated through the hollow anode shaft to further reduce the bearing temperatures.
