61. Scintillator materials of garnets for a fast timing in a harsh radiation environment of collider experiments

Mikhail Korjik (Byelorussian State University (BY))

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,...

59. Prospects for a precision timing upgrade of the CMS PbWO crystal electromagnetic calorimeter for the HL-LHC

Andrea Massironi (Northeastern University (US))

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...

60. A High-Granularity Timing Detector (HGTD) in ATLAS: Performance at the HL-LHC

Nikola Makovec (LAL-Orsay (FR))

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...
