Prototype of the readout electronics for the RICH PID detector in the STCF
文献摘要:
The ring imaging Cherenkov(RICH)detector for particle identification(PID)is being evaluated for the future super tau-charm facility(STCF)complex.In this work,the prototype readout electronics for the RICH PID detector is designed.The prototype RICH PID detector is based on a thick gas electron multiplier combined with a micromegas detector for Cherenkov light detection.Con-sidering that there will be a large number(~690,000)of detector channels in future RICH detector,the readout electronics faces many challenges to precisely measuring time and charge information,such as reducing the noise,increasing density,and improving precision.The require-ments of the readout electronics are explored,the down-selection of the ASICs is made and thus a prototype readout electronics is designed and implemented.Tests are also conducted to evaluate the performance of the proto-type readout electronics,and the results indicate that the time resolution is better than~1 ns(RMS)when the input charge is greater than~12 fC based on the APV25 chip,while the time resolution is better than~1 ns(RMS)at an input charge of over~48 fC based on the AGET and STCF ASIC chips,and the equivalent noise charge is better than~0.5 fC(RMS)@20 pF based on the three ASICs.The test results indicate that the prototype readout electronics design meets the requirement of the future RICH PID detector and thus provides a reference for future engineering.
