摘要：

The ring imaging Cherenkov (RICH) prototype detector, which is based on a thick gaseous electron multiplier+micro mesh gas (THGEM+Micromegas) hybrid detector structure to detect Cherenkov light, is one of the technical options for particle identification of charged hadron (π/K/p) at the super tau-charm facility (STCF). The setup of 1 024-channel verification electronics system for the RICH prototype detector and the test result with the detector were presented. The verification electronics system imports signal from the RICH prototype detector through high-density connectors, and uses the AGET and ADC ASICs for signal amplification, shaping, and waveform digitization. The digital data are then processed by the FPGA and finally transferred to a remote PC for data analysis. The results show that the system equivalent noise charge (ENC) is less than 0.3 fC and the good input-output linearity is achieved with an input dynamic range of 120 fC. The verification electronics system is successfully applied in the beam test of the RICH prototype detector, and good Cherenkov light images are obtained. © 2020, Editorial Board of Atomic Energy Science and Technology.
