DEPENDENCE OF TRAP DEPTH ON DOSE OF THERMALLY-STIMULATED EXOELECTRON-EMISSION DOSIMETERS.

GERALD DUANE SMITH, Purdue University

Abstract

The dependence of exoelectron trap depths on dose for several lithium and calcium dosimeter compounds was investigated. A gas flow detection chamber was designed and built to detect the exoelectron emissions; samples were placed in the cavity of a movable tray where a heater, controlled by a temperature programmer, raised the temperature of the sample from 300 K to 700 K in about six minutes. Pulses from the detection chamber were amplified, shaped, and counted, and then stored in a multichannel analyzer operated in multiscaler mode. Output data were recorded on an X-Y plotter and printed on paper tape for glow curve analysis.
