ABSTRACT:
The present invention is directed to a method and apparatus for generating x-rays employing a vacuum x-ray tube wherein the entire tube housing containing an x-ray emitting anode and an electron emitting cathode is rotated about an axis with means for focussing electrons from the cathode onto a region of the anode. Heat is conducted from the anode to an extended cooling surface remote from the anode by varied heat conduction tailored to produce a substantially uniform temperature over the cooling surface.
