Abstract
A method for determining the heating time constant of a cathode of an X-ray tube. The value of a boost current applied during a preliminary period must be a function of both a pre-existing heating holding current and a service current to be used subsequently. A model of evolution of cathode temperature produces a minimizing tube current error between a tube current that is expected for the tube and a tube current obtained. The model requires only four parameters that need to be computed.
