ResumoA study at various temperatures has been made of approximately a dozen TlBr single crystals in order to find their properties as radiation induced conduction counters. Use of alpha particle sources showed whether holes or electrons were responsible for the observed behavior. Gamma ray studies showed rudimentary spectrometric performance whereas alpha particles usually resulted in peaks of approximately 25% fwhm. Long rise times were observed in some crystals and shorter rise times in others, the variability accounting for as much as a factor of 6. The energy required to produce a free electron-hole pair was observed to be 10.3 ± 2 eV. Breakdown phenomena were observed near room temperature and are described in the text.
