The ATLAS Pixel Detector is the innermost detector of the ATLAS experi-
ment at the Large Hadron Collider at CERN, providing high-resolution mea-
surements of charged particle tracks in the high radiation environment close
to the collision region.
The operation and performance of the Pixel Detector during the first years of LHC running are described. More than 96% of the detector modules...

This talk presents the results of searches for various physics channels in proton-proton collisions at $\sqrt{s}=7$ and 8 TeV delivered by the LHC and collected with the CMS detector. Many obtained results crucially depend on the performance of the CMS pixel detector. Among others b- and tau-tagging as well as primary and secondary vertex reconstruction algorithms are discussed. Application...

Since the beginning of its operation the CMS Silicon Pixel detector performed very well. The operational challenges included the maximization of data taking efficiency, dealing with beam gas interactions and single event upsets, and the recovery of lost modules. The data acquisition techniques also had to adapt to the rapidly changing LHC beam conditions. In order to maximise the physics...

The ALICE Silicon Pixel Detector (SPD) constitutes the two innermost layers of the ALICE experiment, which is the LHC experiment dedicated to the investigation of strongly interacting matter in heavy-ion collisions.
The SPD consists of ~10 million silicon pixels organized in two layers at radii of 39 mm and 76 mm that cover a pseudorapidity range of |η|<2 and |η|<1.4, respectively.
It...

With the increasing radiation dose accumulated by the ATLAS Pixel Detector at the
LHC, effects of radiation damage become more and more visible due to the creation of silicon crystal defects. The monitoring of the detector reveals an increase in the leakage current, which is proportional to the rising radiation dose. Measurements of the effective depletion voltage show a general trend of...

The CMS pixel detector is the innermost component of the CMS tracker occupying the region around the center of CMS, where the LHC beams are crossed, between 4.3 cm and 30 cm in radius and 46.5 cm along the beam axis. They are operated in a high-occupancy and high-radiation environment created by particle collisions in the LHC. Studies of radiation damage effects to the sensors were performed...

The detailed characterization of quark gluon plasma (QGP) produced in heavy-ion collisions is the main goal of the ALICE experiment at CERN LHC. The analysis of heavy quarks via the decays of their short-lived hadrons is among the prominent measure to address the in-medium properties of QGP. To efficiently reconstruct these decays ALICE comprises a precise Inner Tracking System (ITS) made out...
