Design and optimization of the CSA-based readout electronics for STCF ECAL
Description
In this paper, a front-end electronics system based on charge sensitive amplifier (CSA) is designed to read out the signal of pure CsI (pCsI) crystal, which is the basic option of Super Tau-Charm Facility (STCF) electromagnetic calorimeter (ECAL). By noise analysis and on-board testing, parameters of the readout circuit are optimized. Thus the noise of the system with large input capacitance of avalanche photodiode (APD) is significantly reduced. A noise level of 675 electrons for electronics alone and 1025 electrons with S8664-0505 APD is realized, which satisfies the project requirements.
