A new era of hadron collisions will start around 2029 with the High-Luminosity LHC which will allow to collect ten times more data than what has been collected during 10 years of operation at LHC. This will be achieved by higher instantaneous luminosity at the price of a higher number of collisions per bunch crossing.
In order to withstand the high expected radiation doses and the harsher...
Calorimetry at the High Luminosity LHC (HL-LHC) faces two enormous challenges, particularly in the forward direction: radiation tolerance and unprecedented in-time event pileup. To meet these challenges, the CMS Collaboration is preparing to replace its current endcap calorimeters for the HL-LHC era with a high-granularity calorimeter (HGCAL), featuring a previously unrealized transverse and...
The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase 2 upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). A new timing detector for CMS will measure minimum ionizing particles (MIPs) with a time resolution of ~30-40 ps. The precise timing information from the MIP timing detector (MTD) will...
The Liquid Argon Calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward calorimetry in the region from |η| = 1.5 to |η| = 4.9. They also provide inputs to the first level of the ATLAS trigger. In 2022 the LHC started its Run-3 period with an increase in luminosity and pile-up of up to 60 interactions per...
The increased particle flux expected at the HL-LHC poses a serious challenge for the ATLAS detector performance, especially in the forward region which has reduced detector granularities. The High-Granularity Timing Detector (HGTD), featuring novel Low-Gain Avalanche Detector silicon technology, will provide pile-up mitigation and luminosity measurement capabilities, and augment the new...
Timing measurements are critical for the detectors at the future HL-LHC, to resolve reconstruction ambiguity when the number of simultaneous interactions reaches up to 200 per bunch crossing. The ATLAS collaboration therefore builds a new High Granularity Timing detector (HGTD) for the forward region. A customized ASIC - ALTIROC - has been developed, to read out fast signals from low gain...
The ALICE experiment, optimized to study the collisions of nuclei at the ultra-relativistic energies provided by the Large Hadron Collider (LHC), is approaching a new upgrade phase, foreseen during the third Long Shutdown (LS3) of the accelerator (2026-2028). This upgrade includes the replacement of the 3 innermost layers of the current Inner Tracking System (ITS), the detector closest to the...
ATLAS is currently preparing for the HL-LHC upgrade, with an all-silicon Inner Tracker (ITk) that will replace the current Inner Detector. The ITk will feature a pixel detector surrounded by a strip detector, with the strip system consisting of 4 barrel layers and 6 endcap disks. After completion of final design reviews in key areas, such as Sensors, Modules, Front-End electronics and ASICs, a...
Micromegas (MICRO-MEsh GAseous Structure) gaseous detectors are under development for the past three decades. The specific technology has emerged as a versatile platform for radiation detection and imaging, offering good detection efficiency and spatial resolution, excellent timing properties, radiation hardness and reasonable production and operation costs. This talk will present an overview...
The most important ATLAS upgrade for LHC run-3 has been in the Muon Spectrometer, where the replacement of the two forward inner stations with the New Small Wheels (NSW) introduced two novel detector technologies: the small-strip Thin Gap Chambers (sTGC) and the resistive strips Micromegas (MM). The integration of the two NSW in the ATLAS endcaps marks the culmination of an extensive...
The CMS experiment at the LHC has started data taking in Run 3 at a pp collision energy of 13.6 TeV. A highly performing muon system has been crucial to achieving many of the physics results obtained by CMS. The legacy CMS muon detector system consists of Drift Tube chambers in the barrel and Cathode Strip Chambers in the endcap regions, plus Resistive Plate Chambers in both, barrel and...
In High Energy Physics, Resistive Plate Chamber (RPC) detectors operated in avalanche mode make use of a high-performance gas mixture. Its main component, Tetrafluoroethane (C2H2F4), is classified as a fluorinated high Global Warming Potential greenhouse gas.
The RPC EcoGas@GIF++ Collaboration is pursuing an intensive R&D on new gas mixtures for RPCs to explore eco-friendly alternatives...
The Large Hadron Collider (LHC) Run 3 started in 2022. It was preceded by an extensive upgrade period. Among the notable enhancements to the ALICE experiment is the new Fast Interaction Trigger (FIT) detector. FIT is a crucial sub-detector generating fast triggers, providing online luminosity, initial vertex position, and forward multiplicity. A shift crew continuously monitors ALICE Run 3...
At the High luminosity LHC, the expected instantaneous luminosity of up to 7.5 x1034 cm-2 s-1, a factor 7.5 larger with respect to the nominal LHC one, and the integrated luminosity increase by a factor 10 impose severe challenges for the ATLAS detector. The radiation is expected to reach unprecedented values, with non-ionizing fluence of 1e16 neq/cm2 and ionizing dose of 5 MGy. To cope with...
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with 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 every 25...
The LVK network of gravitational waves detectors is currently operating its fourth observing run O4. The second generation interferometers underwent several important upgrades alternating with observation runs during the last decade, in order to approach the design sensitivity. My talk will review the various detector’s changes and the corresponding sensitivity evolution since the first...
