| titleOfInvention | PHOTOCATODE ASSEMBLY OF A VACUUM PHOTOELECTRONIC DEVICE WITH A SEMI-TRANSPARENT PHOTOCATODE BASED ON GALLIUM NITRIDE COMPOUNDS |
| abstract | The utility model relates to photocathode nodes of vacuum photoelectronic devices operating in the ultraviolet region of the spectrum and containing a photocathode based on gallium nitride compounds, and can be used in the construction of electron-optical converters with direct image transfer, photoelectronic multipliers and coordinate-sensitive detectors with microchannel amplification, manufactured by separate processing of photocathode and body parts. In the photocathode assembly of a vacuum photoelectronic device with a translucent photocathode, layers of the heteroepitaxial structure of gallium nitride compounds as a translucent photocathode are grown on the inner surface of the input window made in the form of a sapphire disk. On the outer surface of the inlet window along its periphery, a bimetal-made element for connecting the inlet window with the casing of the vacuum photoelectronic device made of bimetal is tightly fixed. A bimetal layer not in contact with the outer surface of the inlet window consists of a material with a temperature coefficient of linear expansion that differs from the temperature coefficient of linear expansion of sapphire by no more than 10% in the temperature range from 20 to 200 ° C. The utility model expands the scope of application of the photocathode assembly of a vacuum photoelectronic device with a translucent photocathode, increases the quantum yield of the translucent photocathode of the photocathode assembly of a vacuum photoelectronic device, provides a requirement for uniform resolution across the working field of the screen of a vacuum photoelectronic device when using a photocathode assembly as part of an electron-optical converter with direct image transfer. |
