Title: X-ray generator
Inventor: YAMAMOTO NAOKI
IPC: G21K5/02
Filed: 1989-03-24
Abstract: PURPOSE:To provide the X-ray generator as a static type and to eliminate the problem of oscillation by setting an electron releasing source so as to enclose the circumference of a metallic material and expanding the area of an X-ray radiating part with respect to the device adequate for an X-ray analysis apparatus of a fine region. CONSTITUTION:The X-rays 5 are radiated when an electron beam 4 is projected to the material 1 consisting of the metal, etc. The luminance of the radiated X-rays 5 is approximately highest in the same direction as the material surface when the incident electrons are made incident from the direction perpendicular to the surface. The X-rays 5 directed in an axial direction are, therefore, radiated. The electrons emitted from filaments 3 are radiated to the material 1 without almost losing, because the electrons are repulsed by minus electrodes 6 disposed at the most outside positions. The luminance is consequently increased without increasing the input electric power and the generation of the X-rays 5 having the high directivity is possible. The radiation area is increased by providing ruggedness in parallel with the axis on the surface of the central material 1 and, therefore, the X-rays having the higher luminance are obtd.
