Abstract

The results of two-channel multiplier life tests in ultra-high vacuum are presented. In both cases the mean charge output was found to decrease progressively and to vary approximately as the reciprocal of the total number of counts for counts in excess of 1010. A mechanism for this decrease is suggested.
