MICRO-CHANNEL MULTIPLIER RELATIVE TO THE PHOTOCATHODE AND THE SCREEN UNIT IN THE ELECTRONIC OPTICAL CONVERTER POSITIONING ARRANGEMENT METHOD, MICRO-CHANNEL MULTIPLIER RELATIVE TO THE PHOTOCATHODE AND THE SCREEN UNIT IN THE ELECTRONIC OPTICAL CONVERTER POSITIONING DEVICE Russian patent published in 2018 - IPC H01J31/50 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electronic equipment, namely to the microchannel multiplier relative to the photocathode and the screen unit in electron-optical converters (hereinafter, the EOC) positioning arrangement methods and devices. Microchannel multiplier relative to the photocathode and the screen unit in the EOC positioning arrangement method includes use of the housing, photocathode, screen unit, microchannel electronic multiplier, which is made providing the electrons secondary emission, microchannel electron multiplier placement between the photocathode and the screen unit. In addition, using the microchannel multiplier retainer, and the housing is made containing the first coupling assembly, which is configured to provide tightness and alignment during assembly with the screen unit, second coupling assembly, which is configured to provide tightness and alignment during assembly with the photocathode, cermet assembly unit, which is made in the form of a set of rings connected together by the soldering through silver solder under protective atmosphere, microchannel electron multiplier location assembly, which is made containing two rings welded together, at that, the first ring outer diameter is made equal to the housing diameter, the second ring inner diameter is made larger than the microchannel electron multiplier diameter.

EFFECT: increase in the electronic optical converters resolution limit, reliability and ease of assembly, reduction in the failed products percentage during operation.
