摘要
Anode life in an x-ray tube is extended by applying a reduced power density to the anode to afford controlled heating of the anode to a predetermined ductile temperature prior to operating the tube at full power. Controlled heating of the anode is accomplished by defocusing the electron beam for a period of time sufficient to enable the anode to reach the desired temperature. The electron beam source of the tube may also be controlled during heating of the anode so as to supply a reduced beam current.
