Abstract (en)
[origin: EP0241726A1] 1. An image intensifier tube with an axially symmetrical structure comprising a cathode assembly equipped with an input surface with a photocathode and at least one exhaust tube, an anode cone with a small-diameter aperture through which the electrons pass and which tightly girdles the electron flow at this point, a display screen electrode attached to a phosphor screen mounted in an output window with several annular isolating elements that are joined with the electrodes or their mounts vacuum-tight in such a way that, together with these, they form a vacuum envelope while at the same time keeping the electrodes isolated and at the proper distances from one another, characterized in that a multi-channel plate array for electron amplification (8) is situated just before the phosphor screen (7), that a housing section consisting of two annular metallic parts (11a, 11b) is inserted between the multi-channel plate array (8) and the anode cone (6), both parts of which (11a, 11b) bear outward-pointing flanges (12), and that the vacuum-tight joint between these two annular parts (11a, 11b) is implemented in such a way at the circumference (13) of the flanges (12) that it can be reseparated by machining away metal at the circumference (13) of the flanges (12).
