Abstract:
The work is developed a numerical-analytical approach to modeling thermal processes in a composite
anode of microfocus X-ray tubes. At the first stage of modeling, with the help of well-known analytical
approximations, the distribution function of volumetric heat sources is built. At the second stage, this function is
used when solving a stationary boundary value problem with the Poisson equation by the Finite Elements Method.
Using the proposed technique, an adequate assessment of the maximum power of the tube with the transmission
type W-Be anode was developed.
