Paper Abstract

The multi-alkali photocathode is manufactured on glass surface. The cleanliness of glass surface affects greatly the sensitivity of photocathode. The experience proved that the glow discharge process of glass surface could improve the photocathode sensitivity, but superfluous glow discharge process could also increase the carbon-content of the surface, so that bring on the decay of photocathode sensitivity. This article introduces the effect of glow discharge on photocathode sensitivity and its stability.
