Abstract

The photocurrent spectra of supercritical xenon fluids doped with anthracene and TMAE (tetrakis-dimethylaminoethylene) were measured in an attempt to study the nature of small photocurrent peaks for the anthracene/xenon system and the absolute value of the photoionization quantum yield of TMAE in xenon. The density dependence of current peaks at low densities is found to be different from that in the high-density region. It is noted that the high quantum yield of the TMAE/xenon system and its high electron mobility may make this system suitable for application to a high-energy particle detector
