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...
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...
The increase of the particle flux (pile-up) at the HL-LHC with luminosities of L ≃ 7.5 × 1034 cm−2s−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...
CMS is building a High Granularity sampling Calorimeter (HGCAL), which will replace the existing endcap calorimeters (electromagnetic and hadronic) as part of the CMS phase-II upgrade to prepare for the High-Luminosity phase of the LHC (HL-LHC), due to start around 2027. The HGCAL includes two compartments: the CE-E and CE-H for measurements of electromagnetic and hadronic showers...
The Electromagnetic Calorimeter (ECAL) of the CMS detector has played an important role in the physics program of the experiment, delivering outstanding performance throughout data taking. The High-Luminosity LHC will pose new challenges. The four to five-fold increase of the number of interactions per bunch crossing will require superior time resolution and noise rejection capabilities. For...
The Silicon-Tungsten ECAL (SiW-ECAL) of ILD will require about 10,000 detector slabs of 1.4 to 1,8 m in length. For the ease for building and testing, the slabs are made of stitched detector elements of 18×18 cm², composed of a Front-End Board (FEB), hosting the readout ASICs for 1024 channels, on which the Silicon sensors are glued.
Various types of detector elements have been successfully...
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment. TileCal uses steel as absorber and plastic scintillators as active medium. The scintillators are read-out by the wavelength shifting fibres coupled to the photomultiplier tubes (PMTs). The analogue signals from the PMTs are amplified, shaped, digitized by sampling the signal...
The Analog Hadron Calorimeter (AHCAL) concept developed by the CALICE collaboration is a highly granular sampling calorimeter with 3*3 cm^2 plastic scintillator tiles individually read out by silicon photomultipliers (SiPMs) as active material.
After building a large technological prototype and testing it in particles beams at DESY and CERN in 2018, the hardware developments and tests are now...
The Semi-Digital Hadronic CALorimeter (SDHCAL), developed within the CALICE collaboration, is proposed to equip the future ILD detector of the ILC.
A technological prototype has successfully has provided excellent results in terms of energy linearity and resolution but also tracking and PID capabilities.
To validate completely the SDHCAL option for ILD, new R&D activities have started. The...
FCAL performs R&D for highly compact electromagnetic calorimeters foreseen to instrument the very forward region of a detector at future e+e− colliders. Two special calorimeters are foreseen, the Luminosity Calorimeter (LumiCal) and the Beam Calorimeter (BeamCal), for a precise and fast, potentially bunch-by-bunch, luminosity measurement. During the last years FCAL has studied finely-segmented...
The very high luminosity reach of the FCC-ee is obtained by having separate storage rings for electrons and positrons, which cross at a +/- 15 mrad angle at the interaction points, and by strong focussing obtained via by a set of quadrupoles the last of which has it face at L*=2.2 m from the IP. The crossing of the beam lines by the detector solenoidal field necessitates the insertion of a set...
The very forward region of a detector at future e+e- collider is the one of the most challenging regions to instrument. A luminometer – compact calorimeter dedicated for precision measurement of the integrated luminosity at a permille level or better is needed. Here we review a feasibility of such precision at CEPC, considering systematic effects arising from the detector mechanical precision...
Highly granular electromagnetic calorimeter based on scintillator strip with SiPM readout (Sc-ECAL) is under development in the framework of the CALICE collaboration for future electron-positron colliders such as ILC and CEPC. The fully integrated technological prototype with 32 layers has been constructed to demonstrate the performance of Sc-ECAL with more realistic technical implementation....
strong text We present status of scintillator ECAL development in Shinshu University. In particular, we are manufacturing and adjusting an ILC type module that integrates a readout electronic circuit and a scintillator sensor in a layer. We have manufactured two layers of such module, and have made fine adjustments to calibrate. Currently, we are conducting performance verification using...
The scintillator-based electromagnetic calorimeter (ScECAL) is one of the technology options for ECAL at future electron-positron colliders. The performance of double-sided SiPM redout method on scintillator strip and strip-SiPM misalignment effect have been studied in lab test. The performance of the calorimeter with a realistic design of the scintillator strip including the measured...
Electromagnetic calorimeter based on scintillator strip with SiPM readout (Sc-ECAL) is one of the technology options for the ECAL at the International Linear Collider (ILC). The SiPM output will become non-linear light when a large amount of light is injected to SiPM and SIPM saturates. The SiPM saturation is measured with a new method based on scintillation light excited by injecting UV-laser...
