Detector, with a sensitive area of ~1.9 m2 and 92 million pixels. Its original part,
consisting in 3 layers of planar pixel sensor is continuously operating since the start
of LHC collisions in 2008, while Its innermost layer, the Insertable B Layer (IBL) at
about 3 cm from the beam line, was installed in... -

In 2024 the Belle II experiment resumed data taking after its Long Shutdown 1, which was required to install a two-layer pixel detector and upgrade components of the accelerator. We describe the challenges of this upgrade and report on the operational experience during the subsequent data taking. With new data, the SVD confirmed high hit efficiency, large signal-to-noise and good...

The innermost tracking system of the CMS experiment consists of two tracking devices: the Silicon Pixel and Silicon Strip detectors. The tracker was specifically designed to very accurately determine the trajectory of charged particles or tracks, enabling precise reconstruction of primary and secondary vertices, as well as momentum measurements, in the high-luminosity environment of the LHC....

The ATLAS experiment will replace its existing Inner Detector with the new Inner Tracker (ITk) to cope with the operating conditions of the high-luminosity phase of the LHC (HL-LHC) scheduled to start in 2030. ITk is an all-silicon tracker with a pixel detector core surrounded by a strip detector resulting to an almost 180 m2 total silicon surface. This new tracker is designed to withstand the...

The HL-LHC will provide instantaneous luminosities up to $7.5 \times 10^{34}~$cm$^{−2}$s$^{-1}$, and the increased interaction rate and particle flux will degrade the ATLAS event reconstruction performance. The endcap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has degraded resolution will be particularly affected. A High-Granularity...

The High-Luminosity Large Hadron Collider (HL-LHC) will significantly increase the instantaneous luminosity of proton-proton collisions, pushing the CMS experiment into a regime of extreme radiation levels, high particle multiplicities, and unprecedented data rates. To maintain and extend the physics performance of the CMS detector under these conditions, a complete replacement of the tracking...

The vertex detector is a critical component of the future lepton collider, such as Circular Electron Positron Collider (CEPC). It is designed to achieve extremely high spatial resolution (3–5 micrometers) for precisely tracking the decay vertices of particles, particularly in studies related to the Higgs boson.
Significant progress has been made in the development for silicon vertex...

ALICE 3, a next-generation heavy-ion experiment at the LHC, is proposed as part of the Phase IIb upgrades during the fourth long shutdown (LS4), scheduled in 2034-2035, with data taking planned from Run 5. ALICE 3 aims to exploit the full potential of the High-Luminosity LHC as a heavy-ion collider, targeting an integrated luminosity of 35 nb$^{-1}$ in Pb$-$Pb and 18 fb$^{-1}$ in pp...

The LHCb experiment is planning a major upgrade (Upgrade II) during the LHC Long-Shutdown 4 to fully exploit the flavour physics potential of the High Luminosity LHC. The Upstream Tracker (UT), a silicon strip subdetector and key component of the current LHCb tracking system, will have to be upgraded to tackle the higher event rate and harsher radiation environment. A MAPS-based pixel UT has...

Presenting on behalf of the Mighty-Tracker collabration of the LHCb experiement
Abstract
The LHCb experiment at CERN’s Large Hadron Collider is a forward spectrometer optimised for precision studies of heavy-flavour physics, with a particular focus on CP violation and rare decays of beauty (b) and charm (c) hadrons. To fully exploit the High-Luminosity LHC (HL-LHC), where LHCb will...

Radiation-tolerant CMOS active pixel sensors (APS) are demanding for imaging and monitoring systems in high-energy physics facilities, nuclear power plants and aerospace applications. However, the Total Ionizing Dose (TID) effects can significantly degrade image quality due to increased dark current and deteriorated transistors characteristics. This work presents a radiation-hardened CMOS...
