This document describes the development of control systems for positron emission tomography (PET) detectors. It outlines improvements made to the existing ClearPEM Detector Control System, including more robust power supply and temperature monitoring. A new ClearPEM-Sonic Detector Control System was developed with additional chiller control and service board monitoring capabilities. The service boards for both systems were calibrated, achieving high precision for threshold voltage, bias voltage, and temperature measurement. Testing showed the systems function reliably and can handle error conditions.
