Abstract
Low‐density deposits of KCl showing stable secondary electron gains of 30 to 60 in transmission have been prepared by evaporation in an argon atmosphere. The layers have a fast response, high resistivity, and long life under primary electron bombardment. Measurements of their electrical properties suggest that the emission current consists entirely of true secondary electrons and no avalanche multiplication processes occur in the region of stable operation. Practical application of these layers as dynodes in electron multipliers and image intensifiers and as targets in camera tubes is discussed in some detail.
