ABSTRACT:
An X-ray tube assembly having a cathode, an anode, and an electron collector surrounded by a vacuum-enclosing frame. Electrons from the cathode strike a focal point on the target surface of 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. The electron collector preferably is positioned to intercept backscattered electrons which have the highest energy density trajectory of any electrons backscattered directly from the focal point that would otherwise strike the frame creating a thermal hot spot in the absence of the electron collector. Reducing or eliminating the thermal hot spot reduces or eliminates the heat that would otherwise be conducted to the window thereby minimizing tube failure.
