In this paper, we propose and study a new method for increasing the power of a microfocus X-ray tube of transmission type. The proposed method is based on the idea of using a heat pipe as a tube anode. A theoretical expression is obtained for the maximum power dissipated at such an anode, depending on the diameter of the electron beam and the thickness of the tungsten target. It is shown that the power of the proposed tube can be many times higher than the power of tubes with standard composite anodes. An electron-optical scheme of a tube with electrostatic focusing is proposed and analyzed.
