ABSTRACT:
An X-ray tube assembly having a cathode, an anode, and an electrode surrounded by a vacuum-enclosing frame. Electrons from the cathode strike a target surface on the anode. Some electrons produce X-rays which exit an X-ray transparent window portion of the frame. Other electrons are backscattered and go on to strike and heat the frame including the window region. The non-electron-emifting electrode typically has a negative electrical potential and is positioned to deflect the backscattered electrons away from the window region which reduces heating thereto and hence minimizes tube failure.
