Abstract : A new design of a sealed rotating anode X-ray tube has been developed which has an X-ray emission power that is a factor of 1.4, 1.6, and 2.0 greater than present-day X-ray tubes operating respectively at 50, 150, and 300 kilovolts with the same target heat load. These power factors are predicted by extensive Monte Carlo calculations relating to electron diffusion and X-ray production in a tungsten target. The tube design incorporates a state-of-the-art metal-ceramic structure which is air cooled and which has many important advantages over present-day rotating anode tubes.
