ABSTRACT:
An input screen of an X-ray fluoromultiplier tube, that is, an X-ray image intensifier tube, wherein an evaporated aluminum film is interposed between a substrate and a fluorescent substance (cesium iodide) film is disclosed.
The input screen according to this invention does not undergo the "charge-up" attributed to the exfoliation or cracks of the cesium iodide film, and can therefore present a picture of extraordinarily high quality.
