Abstract
Pixelated thallium bromide (TlBr) detectors with a thickness of 4.2 mm have been fabricated and investigated with the depth-sensing technique. The energy resolution of the device was improved from 1.95% FWHM to 1.25% FWHM at 662 keV by implementation of the depth correction. The device exhibited an energy resolution of 1.03% FWHM at 662 keV by selecting gamma-ray interaction events occurring underneath the cathode.
