Abstract

The charge collection and energy resolution in liquid rare gas ionization chambers can be improved by doping the liquid with photoionizing molecules. We have observed the remarkable improvement, especially at a low electric field region, in liquid xenon doped with triethylamine (TEA) and trimethylamine (TMA). Furthermore, in order to apply this effect to real gamma-ray detectors, time stability and temperature effect have been investigated.
