Abstract: A prototype front end electronics (FEE) module is designed for the T0 detector in the External Experiment in CSR (Cooling Storage Ring) of HIRFL (Heavy Ion Research Facility in Lanzhou). Based on the Time-Over-Threshold method and NINO ASIC, a total of 6 channels are integrated in the module, and both high precision leading edge discrimination and Charge-to-Time Conversion can be achieved, which satisfies the readout requirement of MRPC (Multi-gap Resistive Plate Chamber). A series of tests were also conducted in the laboratory, including time precision tests with different thresholds and output pulse width tests with different input signal amplitudes. Test results indicate that this prototype module functions well, and the time precision is better than 20 ps in the dynamic range from 100 fC to 2 pC, which is beyond application requirement. Through this work, preparation is made for the future readout system design.
