R&D progress of CEPC HCAL
August 02, 2019
Circular Electron Position Collider (CEPC) is proposed as a Higgs or Z factory. This work introduces the R&D progress of CEPC hadronic calorimeter (HCAL) based on particle flow algorithm (PFA). Two options include digital (DHCAL) and analog (AHCAL) readout are considered. The RPC DHCAL prototype made by CALICE, we have analysis some beam test data. The GEM detector for DHCAL is under developed. Detector cell of AHCAL have been detail studied, including material, light output and uniformity. The construction of a 51cm x51cm 35 layers AHCAL prototype has been started. Our R&D work would surely be more and more integrated into international PFA calorimeter activities.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
