Abstract
A method of balancing X-ray anodes wherein the anode rotor is dynamically balanced separately from the anode target, the anode target is then attached to the anode rotor to provide the assembled anode, and the assembled anode is then dynamically balanced. This sequential balancing method has the advantage that it results in an anode which remains balanced during operation at speeds up to and exceeding the anode's critical speeds, even though the dynamic balancing steps may be performed at speeds substantially below the anode's critical speeds. This is also convenient because at such low balancing speeds, the dynamic balancing steps can be performed in air rather than vacuum without concern for oxidation and spalling of the rotor bearings, excessive vibration, and potential safety concerns.
