CdZnTeSe (CZTS) has attracted attention for applications in X- and gamma-ray detectors owing to its improved properties compared those of CdZnTe (CZT). In this study, we grew processed single crystals CZT CZTS using the Bridgeman method confirm feasibility a dosimeter high-energy X-rays radiotherapy. We evaluated their linearity precision coefficient determination (R2) relative standard deviation (RSD). showed sufficient RSD values lower than 1.5% X-ray dosimetry, whereas CZT's increased dramatically under some conditions. exhibited an R2 value 0.9968 at 500 V/cm, 0.9373 same The response maintains pulse shape various dose rates, are by adding selenium CdTe matrix defect density sub-grain boundaries. Thus, validated that shows better used Further, applicability onboard imager, (>6 MV) image, is presented. proposed methodology results can guide future advances detection.
