Abstract
An apparatus for rapidly achieving stabilized x-ray emissions from an x-ray tube is disclosed. The essentially constant currant characteristics of an x-ray tube are utilized so as to initially establish relatively low voltage (C) but approximately full current (A) operating condition in the x-ray tube during an initial tube preparation time period. Any relatively low energy x-rays emitted during this initial period are of little concern since they are readily absorbed by the usual beam hardening materials placed in the x-ray path. Once the x-ray tube has been stabilized at such relatively low energy output, the operating voltage may thereafter be very rapidly raised to normal operating levels (D) while permitting concurrent rapid stabilization of the relatively small corresponding further required increase in x-ray tube current (B) which, in turn, provides for rapid stabilization of the useful high energy x-ray tube emissions.
