A hyper-precise time reference is needed for characterization measurements of precise timing detector prototypes. The reference detector is normally placed together with a device under test (DUT) in a beam telescope. The time resolution of this reference detector should be considerably better than the time resolution of the DUT. Measurements with MCP-PMTs of the type R3809U-50 by Hamamatsu...
The electromagnetic calorimeter (ECAL) of the Compact Muon Solenoid Experiment (CMS) has been operating at the Large Hadron Collider (LHC) with proton-proton collisions at 13 TeV center-of-mass energy and a bunch spacing of 25 ns since 2015. Challenging running conditions for CMS are expected after the High-Luminosity upgrade of the LHC (HL-LHC). We review the design and R&D studies for 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 detector performance. The pile-up is expected to increase on average to 200 interactions per bunch crossing. The reconstruction and trigger performance for electrons, photons as well as jets and...
The upgrades ATLAS and CMS for the High Luminosity LHC (HL-LHC) highlighted physics objects timing as a tool to resolve primary interactions within a bunch crossing. Since the expected pile-up is around 200, with an rms time spread of 170ps, a time resolution of about 30ps is needed. The timing detectors will experience a 1-MeV neutron equivalent fluence of $\Phi_{eq}=10^{14}$ and...
Several CVD diamond detectors irradiated up to fluence of 5$\cdot $10$^{15}$ protons/cm$^2$ were tested with a 180 GeV pion beam at the Northern Area at CERN in 2018. The main objective was to observe the effect of irradiation on the signal amplitude spectrum with electronics designed for timing purposes.
Many of the detectors were attached to the front-end electronics with a bond- and...
