Temperature characteristics of the radiation detector using the TlBr crystals

The radiation detector was fabricated from the TlBr crystals grown by the TMZ (travelling molten zone) method and the FWHM and transit time of electrons and holes were measured as a function of temperature. The TlBr radiation detector shows the best response characteristics at about 313 K (3.19 K/su...

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