Abstract

PURPOSE:To improve the deposition efficiency of an In ball by storing a Pt foil- machined boat in a basket-like coil coated with Al2O3, then entering the In ball in the boat, heating and evaporating it, and forming an In2O3 film on a CsI input phosphor layer. CONSTITUTION:A CsI input phosphor layer 2 is formed on an Al substrate 1, and an In2O3 film is formed on the rugged surface of the phosphor layer 2. In this case, a Pt foil-machined boat 4 with a thickness of 10-50mum is stored in a basket-like coil 3 coated with Al2O3, in addition, an In ball 5 is entered in the boat 4, and it is heated and evaporated to form an In2O3 film. Thereby, the In ball 5 is evaporated to the last and the deposition efficiency can be improved.

Generally, an image intensifier tube, such as an X-ray fluorophore tube, has its entire input surface on the input side within a vacuum envelope. For this input surface, an input phosphor layer made of C8I is formed on the output side (concave side) of a substrate made of spherically curved Al, and a photocathode is further formed on this input phosphor layer. .

In this case, the -C8I input phosphor is grown into a columnar crystal, making full use of the linear propagation of light to achieve high resolution. Therefore, as shown in FIG. 1, C formed on the A7 substrate 1,
The surface of the I-input phosphor 2 is completely uneven, so that the photocathode formed thereon lacks conductivity, and it is necessary to remove the defects.

By the way, when evaporating an In bulb * AA! At 20g, the entire reducing effect is applied, and even when deposited in an 02 atmosphere, complete indicum oxide is not obtained, and a portion of the indicium oxide is ejected in the form of lower oxides. Accordingly, A7,0. A phenomenon of melt penetration appears, and as the number of times increases, the evaporation efficiency decreases, making it impossible to use even though there is a remaining amount of In bulbs.
