The CMS Inner Tracker (IT) is a central element of the Phase-2 upgrade, designed to sustain and extend tracking performance in the extreme conditions of the High-Luminosity LHC. It will replace the current pixel detector with a new system featuring increased granularity, enhanced radiation tolerance, and extended geometrical coverage, ensuring excellent vertexing and impact parameter...

Starting this year, the Large Hadron Collider will undergo a high-luminosity upgrade. For the ATLAS detector, 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 current Inner Detector will be replaced by an...

The current inner detector of the ATLAS experiment was designed to operate under the conditions of the Large Hadron Collider (LHC). In the forthcoming High-Luminosity LHC (HL-LHC) era, particle densities and radiation levels will increase by approximately an order of magnitude. The instantaneous luminosity is expected to reach unprecedented levels of $7 \times...

The CMS Outer Tracker (OT) extends precision tracking to large radii while introducing novel capabilities for real-time data reduction at the hardware trigger level, a key requirement for operation at the High-Luminosity LHC. Designed to operate in an environment of extreme occupancies and radiation, the OT combines radiation-hard silicon strip and macro-pixel sensors with innovative module...

The Belle II experiment currently records data at the SuperKEKB $e^+e^-$ collider, which holds the world luminosity record of $5.2\times10^{34}$ $\textrm{cm}^{-2}$ $\textrm{s}^{-1}$ and plans to push up to $6\times10^{35}$ $\textrm{cm}^{-2}$ $\textrm{s}^{-1}$, after an upgrade of its interaction region. To cope with the increased backgrounds, a new fully pixelated vertex detector (VTX) is...

During LHC Long Shutdown 3, the ALICE Experiment will replace its innermost tracking layers with a novel, truly cylindrical pixel tracker (ITS3). The detector will consist of three layers of low power ($40\, \mathrm{mW/cm}^2$) Monolithic Active Pixel Sensors (MAPS) thinned to the point of flexibility ($50\,\mathrm{\mu m}$). By bending these sensors into half-cylinders around the beam pipe, the...

The LHCb experiment is a forward spectrometer dedicated to precision measurements of heavy-flavour hadron decays, enabling sensitive probes of physics beyond the Standard Model through studies of CP violation, rare decays, and searches for new weakly coupled particles. In the High-Luminosity LHC era, the experiment aims to collect an integrated luminosity of approximately 300 fb$^{-1}$ at...

The Micro Vertex Detector (MVD) is the first downstream detector of the fixed-target CBM experiment at the future Facility for Antiproton and Ion Research (FAIR). It extends the high-precision tracking towards low momenta in direct proximity of the target with the first station being placed 8cm downstream the interaction point. The four planar stations operate in the target vacuum and are...

ALICE 3 is pursued as the next-generation heavy-ion detector for LHC Run 5. Its design is driven by the need to achieve unprecedented vertexing performance, tracking over a wide range of transverse momenta combined with good particle identification over an extended pseudorapidity range. In order to achieve a pointing resolution better than 10 µm for transverse momenta of 200 MeV/c, three...

The proposed Super Tau-Charm Facility (STCF) is a next generation high-luminosity $e^+e^-$ collider with a designed peak luminosity exceeding $0.5\times{10}^{35}cm^{-2}s^{-1}$. Its inner tracker is required to operate under high-rate and high-background conditions while maintaining an ultra-low material budget. MAPS is considered a promising technology for the STCF inner tracker (ITKM), which...

Mu3e is an experiment currently under construction at PSI, designed to search for the charged lepton flavour violating decay µ⁺ → e⁺e⁻e⁺. It will make use of the πE5 intense DC surface muon beam of 10⁸ µ⁺/s to reach a sensitivity of 2 × 10⁻¹⁵. The nature of this decay imposes strict requirements on the detector system, especially concerning design compactness, material budget, efficiency and...

The GigaTracKer is a hybrid silicon pixel detector of the fixed-target experiment NA62 at the CERN SPS that aims to precisely measure the branching ratio of the very rare $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ decay. The detector was designed to provide measurements of the momentum, direction, and time of beam particles arriving at a rate of 750 MHz. The tracking system consists of four...

PIONEER is an approved experiment at the Paul-Scherrer-Institute (PSI) that aims to measure the charged-pion branching ratio to electrons vs. muons with an accuracy of $0.01\,\%$. This is an order of magnitude improvement in precision compared to its predecessors and approaches the accuracy of the theoretical calculation. The key elements of PIONEER are a high resolution calorimeter built...
