In the last 40 years, use of scintillation inorganic materials based calorimeters has played a crucial role in the discovery of matter properties and contributed to a continuous progress in this technique. Physicists had built a variety of detectors: small detectors based on NaI(Tl), CsI(Na), BaF2, PbF2, and Bi4Ge3O12 and large detectors such as the electromagnetic calorimeter of CMS,...
The upgrade of the Compact Muon Solenoid (CMS) crystal electromagnetic calorimeter (ECAL), which will operate at the High Luminosity Large Hadron Collider (HL-LHC), will achieve a timing resolution of around 30 ps for high energy photons and electrons. In this talk we will discuss the benefits of precision timing for the ECAL event reconstruction at HL-LHC. Simulation studies focused on the...
The expected increase of the particle flux at the high luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L ≃ 7.5 × 1034 cm−2 s−1 will have a severe impact on the ATLAS deetctor performance. The pile-up is expected to increase on average to 200 interactions per bunch crossing resulting in a vertex density that can be larger than 1.5 per mm.
The reconstruction and...
