| titleOfInvention | Photocathode assembly of vacuum photoelectric device with translucent photocathode |
| abstract | The present invention is a photocathode assembly for a vacuum optoelectronic device operating in the ultraviolet spectrum and comprising a photocathode based on a gallium nitride compound, manufactured by separate processing of the photocathode and housing components, and a close-focusing direct view The present invention relates to a photocathode assembly that can be used in a type photoelectric converter, a photomultiplier tube and a microchannel sensitized position detector. In a photocathode assembly for a vacuum photoelectric device having a translucent photocathode, a layer of a heteroepitaxial gallium nitride compound structure is grown as a translucent photocathode on the inner surface of an inlet port provided in the sapphire disk. On the outer surface of the inlet port, a bimetallic element for joining the inlet port to the housing of the vacuum photoelectric element is fixed in a vacuum-tight manner around the inlet port. The bimetallic layer not in contact with the outer surface of the inlet port is made of a material having a linear thermal expansion coefficient that differs by no more than 10% from the linear thermal expansion coefficient of sapphire within a temperature range of 20 ° C to 200 ° C. The present invention broadens the range of use of a photocathode assembly for a vacuum photoelectric device having a semitransparent photocathode, increases the quantum efficiency of the semitransparent photocathode of the photocathode assembly for a vacuum photoelectric device, When used in a type photoelectric converter, it satisfies the requirement of uniform resolution over the operating area of the screen of the vacuum photoelectric element. |
