Fine-grained calorimeters for experiments at CLIC and FCC-ee

  • Speaker: Oleksandr Viazlo (CERN)
  • Status: Accepted for oral presentation
  • Application: Design concepts for future calorimeters at the energy frontier
  • Topic: Particle flow, Simulation and algorithms
  • Abstract: We present optimisation studies for detectors being designed for future e+e- colliders such as CLIC and FCC-ee,using particle-flow calorimetry. Surrounding a large silicon tracker volume, a very fine-grained ECAL is envisaged, with 40 Si-W layers and a lateral segmentation of 5x5 mm2. Beyond the ECAL, a steel-scintillator HCAL is placed, with 60 layers (for CLIC) or 44 layers (for FCC-ee) and scintillator tiles, coupled to SiPMs, with lateral dimensions of 30x30 mm2. The newly developed software chain based on the DD4Hep detector description toolkit is used for the studies, together with the PANDORA particle flow algorithms. Results obtained for photon and jet energy resolution as well as particle identification efficiencies for the two detector models at CLIC and FCC-ee are presented in this talk.
