This report gives of a review the last results of the radiation damage effects in scintillation materials used in high energy physics experiments, that are caused by γ-quanta and high energy hadrons, and neutrons the three main causes of irradiation in the High Luminosity LHC and future FCC. The creation and recovery of color centers, induced radioactivity and harmful radio-luminescence in...

The Tile Calorimeter (TileCal) is the central scintillator-steel sampling hadronic calorimeter of the ATLAS experiment at the LHC. Jointly with other calorimeters it is designed for energy reconstruction of hadrons, jets, tau-particles and missing transverse energy. The scintillation light produced in the scintillator tiles is transmitted by wavelength shifting fibers to photomultiplier tubes...

The High Luminosity LHC (HL-LHC) will provide unprecedented instantaneous and integrated luminosities. The lead tungstate (PbWO4) crystals forming the barrel part of the Electromagnetic Calorimeter (ECAL) of the Compact Muon Solenoid (CMS) will still perform well, even after the expected integrated luminosity of 3000fb-1 at the end of HL-LHC. The avalanche photodiodes (APDs) used to detect the...

The LHCb Calorimeter system consists of four subdetectors: a Scintillating Pad Detector (SPD) and a Pre-Shower detector (PS) in front of an electromagnetic calorimeter (ECAL) which is followed by a hadron calorimeter (HCAL). They are used to select high transverse momentum hadron, electron and photon candidates for the L0 trigger, and provide the identification of electrons, photons and...

The Tile Calorimeter (TileCal) is the hadronic calorimeter of ATLAS covering the central region of the ATLAS experiment. TileCal is a sampling calorimeter with steel as absorber and scintillators as active medium. The scintillators are read-out by wavelength shifting fibers coupled to photomultiplier tubes (PMT). The analogue signals from the PMTs are amplified, shaped and digitized by...

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 new SuperKEKB collider will be an upgrade of the existing KEKB electron-positron asymmetric collider, with a target luminosity of 8×10$^{35}$cm$^{-2}$s$^{-1}$, about 40 times greater than the previous one. The accelerator upgrade is based on the novel low-emittance "nanobeams" scheme. The detector will also be upgraded to cope with the higher luminosity, pile-up and occupancy. We report on...

Further physical programs at the LHC will require a significant increase of the accelerator luminosity throughout the High Luminosity phase of LHC. During this period, charged hadrons and neutrons with fluences higher than 1014 p/cm2 per year in the largest pseudo-rapidity regions of the detectors will have a non-negligible influence on the radiation damage of materials. Moreover,...

The CALICE collaboration is developing highly granular calorimeters for experiments at a future lepton collider primarily to establish technologies for particle flow event reconstruction. These technologies are now also finding applications elsewhere, such as upgrades for the LHC. At the same time, the large data sets collected in an extensive series of beam tests have enabled detailed studies...

Particle Flow Algorithms (PFA) aimed at the jet reconstruction at the particle level, yield the most precise jet energy resolution, up to a factor of two better than the traditional calorimetry. For the precise jet "pattern recognition", highly granular calorimeters are required. They have being developed by the CALICE collaboration starting from the beginning of 2000's. The most demanding...

The CMS Electromagnetic Calorimeter (ECAL) is made of 75848 lead-tungstate scintillating crystals. The LHC has delivered excellent performance in Run2, allowing CMS to record data corresponding to an integrated luminosity of more than 40 fb-1 at 13 TeV. The Run2 luminosity increase has caused higher radiation doses in the ECAL crystals and photodetectors, affecting the light output. The...

LHCb experiment is one of the four main spectrometers at the Large Hadron Collider. The primary goal of LHCb experiment is the search for indirect evidence of new physics in CP violation and rare decays of hadrons, which contain heavy quarks.
The calorimeter system of LHCb consists of four sub-detectors: Scintillator Pad Detector followed by a Preshower detector and then an...

The Particle Flow Algorithm (PFA) is increasingly used in particle physics as a powerful tool to improve jet energy resolution. Recent technology advances allow to fully exploit PFA by combining precise tracking with fine-grained calorimetry. The CMS experiment is currently developing high granularity calorimeter endcaps for its HL-LHC upgrade (CMS HGCAL). The electromagnetic part, as well as...

The expected increase of the particle flux at the high luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L ≃ 7.5×10$^{34}$ 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 missing...
