The High Luminosity Large Hadron Collider (HL-LHC) at CERN is expected to collide protons at a centre-of-mass energy of 14 TeV and to reach the unprecedented peak instantaneous luminosity of $5-7.5x10^{34} cm^{-2}s^{-1}$ with an average number of pileup events of 140-200. This will allow the ATLAS and CMS experiments to collect integrated luminosities up to 3000-4000 fb$^{-1}$ during the...
The High Luminosity LHC (HL-LHC) is expected to deliver an integrated luminosity of $3000-4000\;$fb$^{-1}$ by the end of 2039 with peak instantaneous luminosity reaching to about $5-7.5\times10^{34}$cm$^{-2}$s$^{-1}$. During the Long Shutdown 3 period, several components of the CMS detector will undergo major changes, called Phase-2 upgrades, to be able to operate in the challenging...
The upgrade of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC) will provide a greater number of simultaneous proton-proton collisions, yielding more data for physics analysis, but imposing greater demands on the triggering systems of the detectors. In response, the CMS Collaboration is designing a novel Level-1 (hardware) track trigger using data from the outer tracker. Its...
The High Luminosity upgrade of the CERN Large Hadron Collider (HL-LHC) calls for an upgrade of the CMS tracker detector to cope with the increased radiation fluence, 2.3E16 neq/cm2 (1MeV equivalent neutrons) for the innermost layer while maintaining the excellent performance of the existing detector. An extensive R&D program aiming at 3D pixel sensors, built with a top-side only process, has...
The SuperKEKB accelerator and Belle II experiment have started full operation in 2019, establishing in 2022 a world record with an instantaneous luminosity of 4.7x10^34 cm^-2.s^-1.
To reach the nominal luminosity parts of SuperKEKB will be modified with a time frame currently predicted to be around Long Shutdown 2 in 2026. Thus, the Belle II collaboration is considering the possibility to...
The Belle II Vertex Detector (VXD), which is located around the beam pipe, is one of key sub-detectors in the Belle II experiment that determines the vertex positions. To improve the tolerance for the beam background and reduce the material budget in the outer layers of the VXD, a new silicon strip detector, Thin and Fine-Pitch Silicon Vertex Detector (TFP-SVD), is proposed as a candidate for...
In the high-luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in up to 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). The innermost...
A new all-silicon Inner Tracker (ITk) has been designed for the ATLAS
experiment at the HL-LHC. As part of this, a new pixel detector
consisting of a total area of approximately 12m^2, will be constructed
with planar and 3D pixel modules, mounted onto ring and stave shaped low
mass carbon-fibre support structures. The data will be transmitted
optically to the off-detector readout...
The ATLAS experiment at the Large Hadron Collider (LHC) is currently preparing for an upgrade of the inner tracking detector for High-Luminosity LHC operation, scheduled to start in 2027. The new detectors must be faster and they need to be more highly segmented. The sensors used also need to be far more resistant to radiation, and they require much greater power delivery to the front-end...
With the upgrade of the LHC to the High-Luminosity LHC (HL-LHC), the Inner Detector will be replaced with the new all-silicon ATLAS Inner Tracker (ITk) to maintain tracking performance in a high-occupancy environment and to cope with the increase in the integrated radiation dose.
Comprising an active area of $165\:\mathrm{m}^2$, the outer four layers in the barrel and six disks in the endcap...
Towards the high luminosity (HL) operation of the Large Hadron Collider (LHC), the inner detector of the ATLAS detector is replaced by a fully silicon-based inner tracker (ITk). Its outer parts consist of 22,000 $n^+$-in-$p$ type silicon strip sensors. In order to confirm key properties of the production sensors as well as to establish a flow to perform inspection and monitoring of the basic...
The ALICE experiment is preparing the ITS3, an upgrade of its Inner Tracking System for LHC Run 4. The three innermost layers will be replaced by wafer-scale, truly cylindrical, ultra-thin detector layers, made of Monolithic Active Pixel Sensors. This innovative technology will permit to reduce the material budget even further and to improve the tracking and vertexing capabilities. We will...
Bent Monolithic Active Pixel Sensors (MAPS) provide the basis for the next generation of ultra low material budget, fully cylindrical tracking detectors. In this contribution, results of beam campaigns with 5.4 GeV electrons will be presented. They verify the performance of bent 50 μm thick ALPIDE chips in terms of efficiency and space point resolution after bending them to the ALICE ITS3...
Proceeding into the High-Luminosity era of the LHC (HL-LHC) will see the instantaneous luminosity increase by an order of magnitude. The LHCb detector is expected to see an increase in integrated luminosity from 50 fb$^{-1}$ to as much as 300 fb$^{-1}$ in Run 5. Such an increase prompts an upgrade to the LHCb tracking system: to deal with higher occupancy in high-$\eta$, more interactions per...
