| 发明名称 | Methods and systems for gain calibration of gamma ray detectors | ||
| 摘要 | A method for gain calibration of a gamma ray detector includes measuring signals generated by one or more light sensors of a gamma ray detector, generating one or more derived curves using the measured signals as a function of bias voltage and identifying a transition point in the one or more derived curves. The method also includes determining a breakdown voltage of the one or more light sensors using the identified transition point and setting a bias of the one or more light sensors based on the determined breakdown voltage. | ||

| 主权项 | 1. A method for calibrating a gamma ray detector, the method comprising: measuring signals generated by one or more light sensors of a gamma ray detector; generating one or more derived curves using the measured signals as a function of bias voltage; identifying a transition point in the one or more derived curves, wherein the transition point corresponds to a switch from a horizontal portion to at least one of a curved portion or a vertical portion; determining an onset of a breakdown voltage of the one or more light sensors using the identified transition point; and setting a bias of the one or more light sensors at a predetermined value from the determined onset of the determined breakdown voltage. | ||
