Abstract

An analytical solution for the focal spot temperature is developed for the case of an exponential decay of the electron flux in the anode. The influence of volume heating on the surface temperature is dominated by the parameter (w/δ)2 where w is the focal spot width and δ is a mean depth of penetration. For typical operating conditions, the influence of volume heating becomes important when the focal spot width is less than 500 microns.
