The Tile Calorimeter (TileCal) is the central hadronic calorimeter of the ATLAS experiment at the LHC. Together with other calorimeters, it provides precise measurements of hadrons, jets, taus and missing transverse energy. The monitoring and equalisation of the calorimeter response at each stage of the signal development is allowed by a movable 137Cs radioactive source, a laser calibration...

The Electromagnetic Calorimeter (ECAL) of the Compact Muon Solenoid (CMS) experiment at the LHC is a hermetic, fine grained, homogeneous calorimeter, comprising 75848 lead tungstate scintillating crystals. We highlight the key role of the ECAL in the discovery and elucidation of the Standard Model Higgs boson during LHC Run I. We discuss, with reference to specific examples from LHC Run I, the...

The CMS electromagnetic calorimeter (ECAL) is made of 75,848 scintillating lead tungstate crystals arranged in a barrel and two endcaps. The scintillation light is read out by avalanche photodiodes in the barrel and vacuum phototriodes in the endcaps, at which point the scintillation pulse is amplified and sampled at 40 MHz by the on-detector electronics. The fast signal from the crystal...

ALICE at the Large Hadron Collider (LHC) is the dedicated experiment focused on heavy ion collisions at LHC, to study a de-confined matter of quarks and gluons, called Quark Gluon Plasma (QGP). Among the sub-detector systems in AILCE, there are two types of calorimetry in the central barrel. One is EMCal (Lead-Scintillator, a sampling electromagnetic calorimeter with a WLS fiber and APD...

The LHCb experiment is dedicated to precision measurements of CP violation and rare decays of B hadrons at the Large Hadron Collider (LHC) at CERN (Geneva). It comprises a calorimeter system composed of four subdetectors: an electromagnetic calorimeter (ECAL) followed by a hadron calorimeter (HCAL). In addition the system includes in front of them the Scintillating Pad Detector (SPD) and...

The Large Hadron Collider forward (LHCf) experiment is designed to measure the hadronic production cross sections of neutral particles emitted in the very forward angles in p-p collision at the LHC.
LHCf has reported energy spectra of forward photons and neutral pions at √s = 900 GeV and 7 TeV proton-proton collisions measured at LHC.
Forward spectra can be helpful in verifying cosmic ray...

The intrinsic time structure of hadronic showers influences the timing capability and the required integration time of highly granular hadronic calorimeters for future collider experiments. To evaluate the influence of different active media and different absorbers, dedicated experiments with tungsten and steel hadron calorimeters of the CALICE collaboration have been carried out. These use...

The SDHCAL prototype that was completed in 2012 was exposed to beams of pions, electrons of different energies at the SPS of CERN for a total time period of 5 weeks. The data are being analyzed within the CALICE collaboration. However preliminary results indicate that a highly granular hadronic calorimeter conceived for PFA application is also a powerful tool to separate pions from electrons....

ABSTRACT: We present a study of the showers initiated by high momentum (up
to 100 GeV) positrons, pions and protons in the highly granular CALICE analogue scintillator-tungsten hadronic calorimeter. The data were taken at the CERN PS and SPS. The analysis includes measurements of the calorimeter response to each particle type and studies of the longitudinal and radial shower development. The...

The best jet energy resolution required for precise physics
measurements at ILC is achievable using a Particle Flow Algorithm (PFA) and highly granular calorimeters. As it was shown by CALICE international R&D collaboration, the silicon-tungsten imaging electromagnetic calorimeter provides the best granularity and jet resolution. After proving the PFA concept with physical prototypes in...

The idea of using scintillator strips coupled with Pixelated Photon-Detector(PPD) has provided the ILD an electromagnetic calorimeter(ECAL) option with a lower cost. In the FNAL 2009 beam test, it was found that the prototype calorimeter of 30 layers could meet the stringent requirements of the ILD. Following this, efforts has been made to develop a more feasible ECAL in terms of performance,...

The PHENIX Experiment at RHIC is planning a series of major upgrades that will transform the current PHENIX detector into a new detector, sPHENIX, which will be used to carry out a systematic measurement of jets in heavy ion collisions in order to study the phase transition of normal nuclear matter to the Quark Gluon Plasma near its critical temperature. The baseline design of sPHENIX will...

The Mu2e experiment at FNAL aims to measure the charged-lepton flavor violating
neutrinoless conversion of of a negative muon into an electron. The conversion
results in a monochromatic electron with an energy slightly below the rest mass
of the muon (104.97 MeV). The calorimeter should confirm that the candidates
reconstructed by the extremely precise tracker system are indeed...

The Belle II experiment will operate at the SuperKEKB e+e− collider, designed to reach a peak luminosity of 8×10^35 cm−2 s−1 at the Ypsilon(4S).
The high background environment of SuperKEKB poses serious challenges to the design of the Belle II detector.
In particular, an upgrade of the forward Electromagnetic Calorimeter is foreseen: the new calorimeter will use pure CsI crystals, which...

The MEG experiment yielded the most stringent upper limit on the branching ratio of the flavor-violating muon decay $\mu\rightarrow e\gamma$. A major upgrade of the detector is planned to improve the sensitivity by one order of magnitude.
For the upgrade, 2-inch round-shape photomultiplier tubes (PMTs) on the entrance window will be replaced by $12\times12$ cm${}^2$ Multi-Pixel Photon...
