Particle Flow Algorithms (PFAs) attempt to measure each particle in a hadronic jet individually, using the component or detector subsystem providing the best energy/momentum resolution. The application of PFAs has been shown to achieve energy resolutions of 3 – 4% for hadronic jets produced in a future lepton collider. In this context the CALICE collaboration developed the Digital Hadron...
The ILD silicon-tungsten electromagnetic calorimeter (ILD Si-W ECAL) is a sampling calorimeter with tungsten absorber and highly segmented silicon layers to achieve precise jet energy measurements by particle flow concept. While CALICE is centered on the single ECAL Active Sensor Unit (ASU) prototype and its tests, specific R&D is going on larger scale detector approaching the size of an ILD...
The successful running of the technological prototype of the Semi-Digital Hadronic CALorimter (SDHCAL) proposed to equip the future ILD detector of the ILC has provided excellent results in terms of energy linearity and resolution and also tracking capabilities. Stability with time of the prototype is also successfully tested.
To validate completely the SDHCAL option for ILD, a new R&D...
The Tile Calorimeter is the hadronic calorimeter covering the central region of the ATLAS detector at the Large Hadron Collider. It is a scintillator-steel sampling calorimeter read out via wavelength shifting fibers coupled to photomultiplier tubes (PMT). The PMT signals are digitized and stored on detector until a trigger is received. The High-Luminosity phase of LHC (HL-LHC)expected to...
In 2019-2020, the LHCb collaboration will enter into the Phase I upgrade. The goal is to increase the working luminosity up to 2·1033 cm-2s-1. To achieve this, the hardware based Level 0 trigger will be replaced by a full software trigger. All the events will be read out; the event reconstruction and selection will be done in real time at a large CPU farm.
In the first part of the talk, the...
The expected increase of the particle flux at the high luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L ≃ 7.5 × 1034 cm−2 s-1 will have a severe impact on the ATLAS detector performance. The pile-up is expected to increase on average to 200 interactions per bunch crossing. The reconstruction and trigger performance for electrons, photons as well as jets and...
The High Luminosity LHC (HL-LHC) will integrate 10 times more luminosity than the LHC, posing significant challenges for radiation tolerance and event pileup on detectors, 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...
Within the CALICE collaboration, several concepts for the hadronic calorimeter of a future linear collider detector are studied. After having demonstrated the capabilities of the measurement methods in "physics prototypes", the focus now lies on improving their implementation in "engineering prototypes", that are scalable to the full linear collider detector. The Analog Hadron Calorimeter...
The circular electron and positron collider (CEPC) was proposed as a future Higgs factory. To meet the physics requirements, a particle flow algorithm-oriented calorimeter system with high energy resolution and precise reconstruction is considered. A sampling calorimeter with scintillator-tungsten structure is selected as one of the electromagnetic calorimeter (ECAL) options due to its good...
CALICE scintillator ECAL module which consists of a scintillator strip layer and an embedded electronics layer will be reported. In total 144 scintillator strips whose dimentions (5mmx45mmx2mm thick) are covering 18cm x 18cm surface, where the same size ECAL base unit called EBU, is located behind the strip layer equipping 144 photo-sensors and front end read out system. The amplifier,...
It is widely expected that the non-linear growth of parton densities at low x predicted from linear QCD evolution will lead to gluon saturation. As a decisive probe of gluon saturation, the measurement of forward (3.5 < y < 5) direct photons in a new region of low x (10-5 - 10-6) in proton-nucleus collisions at the LHC is proposed. An extremely high-granularity electromagnetic calorimeter is...
A status report about the options considered for the electromagnetic calorimeter for the Hidden
Sector Detector of the SHiP experiment will be presented. A “cheap” sampling calorimeter is under
design with an unusual requirement that it be able, standalone, to reconstruct the vertex and
momentum of an unknown particle decaying into final states with only 2 or more photons, produced
between 5...
In view of the LHC results, in order to mitigate the cost of an ILC or at least to spread
it in time, the prospect of a staged development for ILC takes consistence.
An initial phase at an energy of about 250 GeV is strongly considered with a hope to go
to 380 GeV or even 500. A rather long stay at low energy suggests to revisit the detector
design for an optimisation which weighs more...
The physics reach and feasibility of the hadron-hadron Future Circular Collider (FCC-hh) with a centre of mass energies up to 100 TeV and unprecedented luminosities is currently under investigation. We will present the current baseline technologies for the calorimeter system of the FCC-hh reference detector: a liquid argon (LAr) electromagnetic and a scintillator-steel (Tile) hadronic...
Future digital and semi-digital hadron calorimeters, will consist of 40-50 layers of thin
sampling elements interposed between absorber planes. The total area coverage of such
elements could reach a few thousands of square meters, thus requiring robust, cost-
effective solutions. The thin, single-element Resistive Plate WELL (RPWELL) detector
concept could be an effective solution for DHCAL,...
