TlBr strip detectors with four anode strip electrodes were fabricated in this study. The strip electrodes were formed on TlBr wafers 1 mm thick with a vacuum evaporation process through a shadow mask. Each strip had a width of 0.8 mm and a length of 3.5 mm approximately. The gap between the strips was approximately 0.1 mm. Inter strip resistance more than 1 GΩ was obtained with the process. Energy resolutions of 7.0% and 3.8% FWHM were recorded for 511 keV and 1.33 MeV gamma-rays, respectively, with the TlBr strip detector at room temperature.
