Description
Semi-Digital Hadron Calorimeter (SDHCAL) prototype for CEPC is a PFA-based hadron calorimeter that has shown good energy and position resolution with a CERN test beam. Considering the signal time of hadronic shower formed by neutrons is delayed, compared with that from charged hadrons, high-precision time measurement, requiring at least 100ps orders, helps improve separation between
neutrons and charged hadrons and further improve the jet energy resolution. The readout electronics with four PETIROC ASIC chips have been designed to validate the high time resolution with tens of ps.
Keywords: CEPC, SDHCAL, PETIROC, ASIC, High Time Resolution.
