UNCOOLED IR DETECTOR FOR THE TEN MICRON REGION.
Abstract
A sample holder and flash apparatus were con structed for measuring the photoconductive re sponse of cadmium sulfide crystals to microsecond pulses of light. The aim of this research is to obtain evidence of photoconductivity due to the thermal ionization of neutral particles generated by the light. There is some evidence that neu tral particles have contributed to the photocur rent when certain sensitive locations of some crystals are illuminated. This is not exactly the anticipated behavior, and experiments now in progress are designed to remove ambiguities in the present evidence. The decay characteristics of the photoconductivity resulting from micro second pulses of light proved to be a fruitful peripheral avenue of research. The interpretation of the measured decay rates is incomplete, but analysis of these rates promises to yield valuable information concerning lifetimes of electron traps. (Author)
