| titleOfInvention | INPUT SCREEN FOR AN X-RAY AMPLIFIER TUBE. |
| abstract | The invention relates to the input screens of radiological image intensifier tubes. The input screen comprises a scintillator (12) deposited on an aluminum substrate (10); it converts incident X photons into visible photons which then excite a photocathode (16). Light photons produced by the scintillator are emitted backwards and reflected by the aluminum layer; but this reflection reduces the resolution. According to the invention, to suppress this reflection, it is proposed to produce an input screen in which a thin layer (20) that is transparent or poorly absorbent (at the wavelengths emitted by the scintillator) is interposed between the substrate and the scintillator. calculated to cause an anti-reflective effect. As low-absorbing anti-reflection layer, indium oxide, or even antimony, tin or bismuth oxide, or even a combination of these oxides, such as oxide, will preferably be chosen. of indium-tin. The thickness is a few hundred to a few thousand angstroms. |
