Abstract (en)
[origin: EP0352152A1] Improvement to the manufacture of a scintillator especially for the input screen of a radiological image-intensifier tube. <??>According to the invention the substrate (11) on which a layer of scintillating material (12) such as caesium iodide deposited in the form of needles (13b) is grown is subjected to a treatment ending in the formation of a surface quality or of an alveolate structure (15) resulting in the formation of finer needles. <??>The reduction in the average diameter of the needles is reflected in an improvement in the resolution of the device. <IMAGE>
