Modern tracking systems are very precise, therefore, in particle flow-like reconstruction algorithms, the jet performance is usually limited by the calorimeter. The need to solve the fat jet substructure favors the design of finely segmented calorimeters. However, this contrasts with the need to have high temporal resolutions for signal events even at low energy deposits: for example due to...
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 technological prototype addresses technical...

The Electron Ion Collider will be a new facility at Brookhaven National Lab that will study the structure of nuclear matter in the gluon dominated regime of QCD using Deep Inelastic Scattering with precision electromagnetic probes. It will utilize the existing RHIC collider to provide beams of polarized electrons from 2.5-18 GeV to collide with heavy ions from 10-100 GeV/A and protons up to...
Many physics analyses using the Compact Muon Solenoid (CMS) detector at the LHC require accurate, high resolution electron and photon energy measurements. The CMS electromagnetic calorimeter (ECAL) is a fundamental instrument for these analyses and its energy resolution is crucial for the Higgs boson mass measurement. Recently the energy response of the calorimeter has been precisely...
A prototype of a digital pixel EM calorimeter, EPICAL-2, has been designed and constructed, following up on a previous prototype [1]. It consists of alternating W absorber and Si sensor layers, with a total thickness of ~20 radiation lengths, an area of $\mathrm{30mm\times30mm}$, and ~25 million pixels. The new EPICAL-2 detector employs the ALPIDE pixel sensors developed for the ALICE ITS...

A highly granular electromagnetic calorimeter has been designed and optimised with particle flow algorithms within the CALICE collaboration for precision measurements of Higgs and electroweak physics at future lepton collider experiments, including the Circular Electron Positron Collider (CEPC). Scintillator strips and silicon photomultipliers (SiPMs) are instrumented as sensitive layers and...
Particle Flow Algorithms (PFAs) attempt to measure each particle in a hadronic jet individually, using the detector subsystem that provides the best energy/momentum resolution. Calorimeters that can exploit the power of PFAs emphasize spatial granularity over single particle energy resolution. In this context, the CALICE collaboration developed the Digital Hadron Calorimeter (DHCAL). The DHCAL...
The FCAL collaboration is preparing large-scale prototypes of special calorimeters to be used in the very forward region at a future electron-positron collider for a precise and fast luminosity measurement and beam-tuning. The LumiCal is designed as a silicon-tungsten sandwich calorimeter with very thin sensor planes to keep the Moliere radius small, facilitating the measurement of electron...
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...
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...
The new CMS High Granularity Calorimeter (HGCAL), being built for HL-LHC, will have unprecedented transverse and longitudinal readout and trigger segmentation. In regions of low radiation, HGCAL will be equipped with small plastic scintillator tiles as active material coupled to on-tile silicon photomultipliers. With respect to earlier developments targeted at a future e+e- collider,...
The HIBEAM/NNBAR experiment is a free-neutron search for n→nbar and n→sterile n oscillations to be housed at the ESS in Lund, Sweden. The detector will be capable of identifying n-nbar annihilation events, which will produce on average ~4 pions with a final state invariant mass of ~1.9 GeV. The detector will feature a novel calorimeter design, which must provide good resolution of the point of...
Mu2e will search for the CLFV conversion of a muon into an electron in the field of a nucleus. A clean discovery signature is provided by the mono-energetic conversion electron (Ee= 104.967 MeV). If no events are observed, Mu2e will set a limit of the ratio between the conversion and the capture rate below 6×10$^{−17}$ (@ 90% C.L.). The calorimeter requirements are to provide Eres < 10%, Tres...
