The TlBr detector is a gamma-ray detector capable of operating at room temperature. In this study, we focused on coplanar grid electrodes, which are expected to offer high energy resolution and detection efficiency, and performed waveform analysis with the aim of improving the position dependence of the pulse height. The results confirmed that the differ among the collection electrodes, suggesting that the introduction of additional correction indicators is necessary in addition to conventional corrections. Moving forward, we aim to further improve performance by optimizing the detector structure and correction methods.
