Abstract
The present invention is directed to an improved spectographic X-ray tube in which heat dissipation through the beryllium window of the X-ray tube is improved by way of a thin layer disposed on the inside of the beryllium window. The coating layer is of copper and disposed on the inside of the beryllium window for the best effects for improving heat dissipation by the window.
Claims5
In an X-ray tube comprising a cathode means for generating electrons, an anode means receiving said electrons for emitting X-rays, a beryllium window separated from said anode means for passing said X-rays, wherein said anode means is mounted on a copper anode block, the improvement comprises a coating layer disposed over the entire surface of said beryllium window for improving heat dissipation by said window upon receiving X-rays from said anode means, wherein said coating layer is a material the same as said anode means, and wherein said coating layer has a thickness ranging from about 500 to 1000 angstroms.
