Particle detectors with a timing resolution of order 10 ps can improve event reconstruction at high luminosity hadron colliders tremendously. 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....
The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). A new timing layer is designed to measure minimum ionizing particles (MIPs) with a time resolution of ~30ps and hermetic coverage up to a pseudo-rapidity of |eta|=3. This MIP Timing...
The CMS hadronic calorimeter employs plastic-scintillator-based sampling calorimeters in the barrel and endcap (HBHE). In Run 2, the LHC operates at 13 TeV center of mass energy with up to 50 simultaneous collisions per bunch crossing (pileup) and a 25 ns bunch spacing. The HBHE scintillator light pulse is only 60% contained in a 25 ns window, resulting in significant pulse overlap for...
The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). In particular, precision timing can offset the performance degradation due to event pileup at the HL-LHC, recovering the purity of vertices of current LHC conditions. As such, a new...
The upgrade of the KEKB e+e− collider to SuperKEKB and of the Belle detector to BelleII has just been completed at KEK (Tsukuba, Japan) and the accelerator is starting the Phase2 operations on March 2018 for a new experiment with high luminosity up to 8×1035cm−2s−1.
We report on the upgrade of the electromagnetic calorimeter (ECL) which will provide good energy and time resolution in a high...
