摘要： In order to give a sufficiently strong adhesive strength to the input screen of an X-ray image tube, to improve the resolution of the output picture of the image tube, and to secure the luminance uniformity of the output picture as necessary, the surface of the input substrate of the image tube composed of aluminum or an aluminum alloy is varnished so that fine recessing and projecting sections of the substrate material can be eliminated from the surface and nondirectional gentle recessing and projecting sections can be left as they are. Such gentle recessing and processing sections that the average distances between adjacent valleys fall within the range of 50-300 mu m and average heights between the crests and valleys fall within the range of 0.3-4.0 mu m are suitable for those to be left as they are. When the input substrate is varnished in the above-mentioned way, the resolution of the output picture of the image tube can be improved because the diffusion of light on the surface of the input substrate is suppressed, and the picture noise which is caused by the fine recessing and projecting sections is reduced.

摘要： The present invention assures a satisfactory adhesiveness of an input screen 13 of an X-ray image intensifier, high resolution of an output image and brightness uniformity as required, by configuring an aluminum or aluminum alloy substrate 21 so to have a concave surface with minute irregularities of the substrate material removed by burnishing, excepting gentle irregularities 21c without directivity which are caused by pressing. The gentle irregularities 21c of the substrate 21 preferably have an average length L in a range of 50 µm to 300 µm between the neighboring bottoms and an average height H in a range of 0.3 µm to 4.0 µm from peaks to bottoms. The invention improves resolution with light on the substrate surface suppressed from being scattered, and decreases image noises which are caused by the minute irregularities.

摘要： An X-ray image intensifier tube (1) comprises an entrance section (2) for converting high-energy X-rays of from 100 keV to 120 keV into an electron beam (10). The entrance section (2) comprises a conversion layer (3) with a filter layer (5) for absorbing a part of comparatively low energy (from 60 keV to 80 keV) of the X-rays and a conversion layer for converting the high-energy X-rays of approximately from 100 keV to 120 keV into radiation whereto the photocathode is sensitive.

摘要： An X-ray image tube comprises a vacuum enclosure, which includes an input window for passing X rays, a metallic frame fitted with the input window, a body, and an output window. The input window and the metallic frame are joined hermetically by ultrasonic welding. The X-ray image tube reduces the distortion of the electron lens formed in the vacuum enclosure.

摘要： A neutron reactant layer (220) is directly coated inside an aluminum substrate (200) of an incident window (20). A first scintillator layer (201) is formed inside the neutron reactant layer 220, and a photoelectric conversion layer (202) is formed inside the first scintillator layer (201). A neutron reactant layer (210) is composed of enriched boron carbide ( 10 B 4 C), and generates α-rays from neutrons by a (n, α) reaction in enriched boron. The first scintillator layer (201) is light-emitted by this α-rays.

Such gentle recessing and processing sections that the average distances between adjacent valleys fall within the range of 50-300 mu m and average heights between the crests and valleys fall within the range of 0.3-4.0 mu m are suitable for those to be left as they are. When the input substrate is varnished in the above-mentioned way, the resolution of the output picture of the image tube can be improved because the diffusion of light on the surface of the input substrate is suppressed, and the picture noise which is caused by the fine recessing and projecting sections is reduced.
