The Loadability Of Rotating Anode X-Ray Tubes

The loadability of a rotating anode X-ray tube is discussed as a function of such parameters as rotational speed, focal spot size and anode material, and in particular the thermal constants. Resulting possibilities for further increasing the output and the additional technical effort involved are discussed. Limits of loadability are indicated. Finally the influence of the intensity distribution on the loadability is discussed and demonstrated in model distributions such as Gaussian or twin-peaked distribution.
