The increase of the particle flux at the HL-LHC with luminosities of L ≃ 7.5 × $10^{34}$ cm$^{−2}$s$^{−1}$ will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected. A High Granularity Timing...
The LHCb Upgrade 2 will run at a luminosity of $(1..2)*10^{34} cm^{-2}s^{-1}$ to collect ~300 $fb^{-1}$ of data. This will require a major revision of the LHCb Calorimeter. The increased luminosity will result in very high particle densities and radiation doses in the central area. The ECAL has to provide high quality energy and position measurement for electromagnetic showers. One option for...
The CMS Collaboration is preparing to build replacement endcap calorimeters for the HL-LHC era. The new high-granularity calorimeter (HGCAL) is, as the name implies, a highly-granular sampling calorimeter with approximately six million silicon sensor channels (~1.1cm^2 or 0.5cm^2 cells) and about four hundred thousand channels of scintillator tiles readout with on-tile silicon...
A dual gain trans-impedance amplifier and an ASIC providing two 160 MHz ADC channels, gain selection, and data compression will be installed. The noise increase in the APDs, due to radiation-induced dark current, will be contained by reducing the temperature at which ECAL is operated. The trigger decision will be moved off-detector and performed by powerful and flexible FPGA processors,...
The FCAL collaboration is preparing large-scale prototypes of special calorimeters to be used in the very forward region at a future e+e- collider for a precise and fast luminosity measurement and beam-tuning. LumiCal is designed as Si_W sandwich calorimeter with very thin sensor planes to keep the Moliere radius small, facilitating such the measurement of electron showers in the presence of...
The Electron Ion Collider (EIC) is a new facility that has been proposed in the US to study the structure of nuclear matter in the gluon dominated regime of QCD using Deep Inelastic Scattering (DIS) with precision electromagnetic probes. Two versions of this facility have been proposed, one at Brookhaven (eRHIC) and another at JLAB (JLEIC). It would have the capability of colliding polarized...
A highly granular electromagnetic calorimeter has been designed and optimised within the CALICE collaboration for precision measurements at future lepton collider experiments, including the Circular Electron Positron Collider (CEPC). Scintillator strips and silicon photomultipliers (SiPMs) are instrumented as sensitive layers and tungsten-copper alloy plates as absorber. Scintillator strips...
The DUNE experiment requires a highly capable near detector system to achieve its ambitious physics goals. One of the subsystems of the near detector is the Multi-Purpose Detector (MPD), which will consist of a high pressure gaseous Argon TPC surrounded by an electromagnetic calorimeter, embedded in a magnetic field. The calorimeter complements the tracking capabilities of the TPC with photon...
A highly granular silicon-tungsten electromagnetic calorimeter (SiW-ECAL) is the reference design of the ECAL for International Large Detector (ILD) concept, one of the two detector concepts for the detector(s) at the future International Linear Collider. Prototypes for this type of detector are developed within the CALICE Collaboration.
The contribution will report for the first time on...
The Analogue Hadron Calorimeter (AHCAL) of the CALICE collaboration is a technological prototype for future linear collider detectors, addressing scalability, integration and engineering challenges imposed by the experimental environment. It is based on the SiPM-on-tile technology, where the active layers of the calorimeter are formed by 3x3 cm2 plastic scintillator tiles placed on top of...
