The CMS Collaboration is preparing to build replacement endcap calorimeters for the HL-LHC era. The new high-granularity calorimeter (HGCAL) was first discussed publicly at CHEF 2013. As the name implies, it is 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...
A new concept of high-granularity calorimetry based on crystals has been proposed for the Circular Electron Positron Collider (CEPC) with an aim to reach unprecedented energy resolution as well as 3D-positioning precision. In this conceptual design, crystals are finely segmented in both transverse and longitudinal directions. Each crystal is optically isolated and read out by a compact...
The electromagnetic (EM) calorimeter with longitudinal segmentation , his design and beam test results are presented. The EM calorimeter of "shashlik" type was divided longitudinally on 4 tiles. The idea of such calorimeter type was an improving the particles identification take in account longitudinal shower profile for electrons, muons and hadrons. This calorimeter via a single...
Traditional energy measurements in hadron detection have always been spoiled by the non-compensation problem. Hadronic showers develop an electromagnetic component, from neutral mesons’ decays, over-imposed on the non-electromagnetic one. As the calorimeter samples the two with different responses, fluctuations between them directly spoil the hadronic energy resolution. This sets an...
The Analogue Hadron Calorimeter (AHCAL) developed by the CALICE collaboration is a scalable engineering prototype for a Linear Collider detector. It is a sampling calorimeter of steel absorber plates and 3*3 cm$^2$ plastic scintillator tiles read out by silicon photomultipliers (SiPMs) as active material (SiPM-on-tile). The front-end chips are integrated into the active layers of the...
Circular Electron Position Collider(CEPC) is aimed at being Higgs and Z bosons factory and precisely measuring the mass of Higgs. High granularity calorimeter which is based on particle flow algorithm(PFA) could achieve the jet energy resolution 3%~4%. One proposal of Hadronic Calorimeter(HCAL) is Analog HCAL(AHCAL) consists of stainless as absorber and scintillator as active layer. This...
The Circular Electron Position Collider (CEPC) has been proposed as a Higgs or Z factory. Particle flow-oriented electromagnetic (ECAL) and hadronic calorimeters (HCAL) comprise a baseline design of the CEPC calorimetry system. The ECAL consists of alternating tungsten and scintillator layers, with the scintillator bottom-coupled to SiPMs. Advanced studies of the single photon response curves...
