Performance of an Improved Methane-Flow Proportional Counter for TSEE.

Abstract : An improved methane-flow proportional counter for detecting thermally stimulated exoelectron emission (TSEE), which permits simultaneous measurements of thermoluminescence and TSEE on a single sample, has been developed. The proportional counter is described, and influences on the day-to-day stability and reproducibility of the counter and associated equipment are discussed.
