By using a further development of
earlier elaborated approach we analyzed dynamics of the thermal field in a
multilayer anode, which rotating with frequency w (material ¹1/AgSn/Cu),
of a X-ray tube with water cooling during pulse irradiation of the anode by
electron ray. Limiting power and surface density of the power of the electron
ray, which correspond to datum value of vapor pressure of materials of the
anode’s target, were estimated. Dependencies of the limiting power and surface
density of the power from surface of electron ray, type of material and
thickness of anode’s target has been analyzed.
