Abstract

The Super Tau-Charm Facility (STCF) is a significant initiative for accelerator-based particle physics in China. Electromagnetic Calorimeter (ECAL) is one of the important detectors of STCF, which is tasked with the accurate measurement of photons. STCF ECAL employs pure Cesium iodide (pCsI) as its scintillation crystal and uses a large-area avalanche photodiode (APD) as a photoelectric conversion device. High luminosity of STCF results in significant background levels, leading to pileups challenging conventional signal processing. In this paper, a pile-up correction algorithm called “pipeline optimal filtering” is proposed, and a background simulation platform is built to verify the measurement effect of the algorithm on energy and time.
