Description
Super Tau-Charm Facility (STCF) is one of the important options for accelerator-based particle physics in China. The operation of the STCF will provide a unique platform for the study of tau-charm physics and hadron physics.
Electromagnetic Calorimeter (ECAL) is one of the important sub-detectors of STCF, and Its core task is the precise measurement of photons. In the face of complex background environment, STCF ECAL needs to obtain accurate energy information and time information of photons at the same time to effectively suppress the background, so compared with traditional electromagnetic energy generators, STCF ECAL puts forward higher requirements for temporal resolution.
STCF ECAL selects pure Csium iodide (pCsI) as its scintillation crystal, and uses a large-area avalanche photodiode (APD) to make up for the shortcomings of low pCsI optical yield.
In order to meet the above readout electronics requirements, this paper determines the energy measurement scheme based on the Charge Sensitive Amplifier (CSA), and uses algorithm to deal with the pile-up signal, and the energy information and time information that meet the measurement requirements of STCF ECAL can be obtained.
In order to meet the needs of high-precision energy and time measurement in the environment of high case rate of STCF ECAL, the readout electronics scheme was studied and designed, and the feasibility of the scheme was verified by combining with the prototype electronics system, which provided a technical basis for the future development of STCF ECAL.
