Abstract :
In this paper, the temperature dependence in the long term stability of the TlBr detector was studied. Systematic measurements of the pulse height spectra and counting rate were carried out. The pulse height spectra showed poor hole collection, worsening with the increase of temperature. The ratemeter measurements showed an aleatory pulse formation that may be attributed to the polarization effect and air moisture in the detector environment.
