The Dual-Readout calorimetry, developed to overcome the main limiting factor in hadronic energy measurements, has been thoroughly investigated by the DREAM/RD52 collaboration during the last 15 years. The latest results show that very interesting performance may be obtained for both e.m. and hadronic showers, together with excellent standalone e/π separation. These results and the plans (and...
The luminosity of the Future Linear Colliders will be measured by counting Bhabha scattering events at low angles coincident in the two calorimeters (LumiCal) located symmetrically at opposite sides of the interaction point. The LumiCal has been designed as a 30 layers sampling calorimeter with tungsten as absorbel and silicon sensors. Each silicon layer composed of 12 tails with 256 pads. In...
The CALICE collaboration develops highly granular calorimeters for present and future collider experiments. Among the physics prototypes already tested extensively in particle beams are Silicon-Tungsten (SiW ECAL) and Scintillator-Tungsten (Sc ECAL) electromagnetic calorimeters and a scintillator – SiPM based analog hadron calorimeter (AHCAL). These prototypes were operated together in hadron...
Increasing precision requirements on particle reconstruction in future collider experiments ask for calorimeter systems with a high granularity. These calorimeters offer a unique and detailed view into electromagnetic and hadronic particle showers. We have performed test measurements with a digital Si-W electromagnetic calorimeter prototype using high granularity Monolithic Active Pixel...
Future circular and linear colliders as well as the Large Hadron Collider in the High-Luminosity era have been imposing unprecedented challenges on the radiation hardness of particle detectors that will be used for specific purposes e.g. forward calorimeters, beam and luminosity monitors. We perform research on the radiation-hard active media for such detectors, particularly calorimeters, in...
As part of its HL-LHC upgrade program, CMS is developing a High Granularity Calorimeter
(HGCAL) to replace the existing endcap calorimeters. The HGCAL will be realised as a
sampling calorimeter, including an electromagnetic compartment comprising 28 layers of
silicon pad detectors with pad areas of 0.5 - 1.0 cm 2 interspersed with absorbers.
Prototype modules, based on 6-inch hexagonal silicon...
We report on the first LHC collision data taken with a 20 degree wedge of
the CMS Hadron Calorimeter Endcap instrumented with SiPMs and the QIE
ASIC version 11 front-end chip.
Operational experience is reported on temperature and gain stability of the
SiPMs. The performance of the front-end ASIC and digital readout are also
presented. The light loss from the darkening of the CMS HCAL...
During the so-called Phase-II Upgrade the CMS experiment at CERN will undergo significant improvements to cope with a 10-fold increase in luminosity of the High Luminosity LHC (HL-LHC) era. Especially the forward calorimetry will then suffer from very high radiation levels and intensified pile-ups in the detectors. Thus, the CMS collaboration is designing a High Granularity Calorimeter to...
The High Luminosity LHC (HL-LHC) will integrate 10 times more luminosity than the LHC, posing significant challenges for radiation tolerance, especially for forward calorimetry, and hallmarks the issue for future colliders. As part of its HL-LHC upgrade program, the CMS collaboration is designing a High Granularity Calorimeter to replace the existing endcap calorimeters. The upgrade includes...
Abstract: The CALICE Semi-digital Hadronic Calorimeter (SDHCAL) prototype with Glass Resistive Plate Chambers is the first technological prototype in a family of high-granularity calorimeters. It was exposed to beams of hadrons, electrons and muons several times on the CERN PS and SPS in 2012, 2015 and 2016. Based on the Boosted Decision trees method, we discuss the effect on the improvement...
