Abstract

The reasons are determinated, that limit sensitivity level of multialkaline photocathodes, formed in UHV chambers, that are comprised "transfer" setup assembly for assembly of super 2+ generation image intensifiers tubes (I²). Analysis of surface and underlying glass layers are performed. On the base of this analysis the methods of cleaning and closing destroyed glass layer to prevent photocathode deterioration are posed. This allows to increase mean level of integral sensitivity to 600 μA/lm.
