Description

Coating with caesium-iodide has been shown to increase the soft X-ray quantum detection efficiency of microchannel plate (MCP) electron multipliers. Measurements are now presented of the stability and reproducibility of such CsI deposition photocathodes. The effects of limited exposure to humid air and of storage in poor vacuum, high vacuum and dessicated air are described. The stability of CsI coatings under prolonged X-ray bombardment is discussed and the mechanical strength of thick (up to 14000 A) CsI layers briefly assessed. (orig.)
