Abstract
The radiation detector was fabricated from the TlBr crystals grown by TMZ ( travelling molten zone) method and the FWHM and transit time of electrons a nd holes were measured as a function of temperature. The TlBr radiation det ector shows the best response characteristics at about 313 K (3.19K(-1)) in cases where holes mainly contributed to the output pulses. However, in the temperatures higher than 300 K (3.33 K-1), the FWHM for Am-241 alpha-parti cles (5.48 MeV) becomes worse. An activation energy of about 0.90eV has bee n deduced from the resistivity measurement.
