The LHC high-luminosity upgrade in 2024-2026 requires the associated detectors to operate at luminosities about 5-7 times larger than assumed in their original design. The pile-up is expected to increase to up to 200 events per proton bunch-crossing. To be able to retain interesting physics events even at rather low transverse energy scales, increased trigger rates are foreseen for the ATLAS...

The Tile Calorimeter (TileCal) is the hadronic calorimeter of ATLAS covering the central region of the
ATLAS experiment. TileCal will undergo a major replacement of its on- and off-detector electronics in 2024 for the high luminosity programme of the LHC.
The calorimeter signals will be digitized and sent directly to the off-detector electronics, where the signals are reconstructed and...

An electromagnetic sampling calorimeter prototype has been developed to satisfy the requirements for running at the CERN Large Hadron Collider after the planned High-Luminosity upgrade (HL-LHC).
An innovative design, with wavelength-shifting (WLS) fibers running along the chamfers of each calorimeter cell, minimizes the mechanical complexity. The resistance to radiation has been optimised by...

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 $\times 10^{34} cm^{−2} s^{−1}$ will have a severe impact on pile-up. 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 transverse...

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....
