The ATLAS Inner Detector based on silicon sensors is consisting of a strip detector (SCT) and a pixel detector. It is
the crucial component for vertexing and tracking in the ATLAS experiment.
With the excellent performance of the LHC well beyond the original specification the
silicon tracking detectors are facing substantial challenges in terms of data acquisition, radiation damage to the...
The ATLAS Forward Proton (AFP) experiment is a detector located ~210 m
away from the ATLAS interaction point on both sides. It's aim is to
tag and measure forward protons produced in diffractive events. The
detector consists of a 3D silicon pixel tracker, to measure the proton
trajectory, as well as a time-of-flight system to suppress
pileup-related backgrounds. Each tracker and the ToF system...
The CMS outer silicon strip tracker with its more than 15000 silicon modules and 200m2 of active silicon area is in its ninth year of operation at the LHC. We present the performance of the detector in the LHC Run 2 data taking. Results for signal-to-noise, hit efficiency and single hit resolution will be presented. We review the behavior of the system when running at beyond-design...
The LHCb detector is a single-arm forward spectrometer with precise silicon-strip detectors in the regions with highest particle occupancies. Around the interaction region, the VErtex LOcator (VELO) has active sensing elements as close as 8 mm from the LHC beams. The Silicon Tracker (ST) consists of a large-area detector located upstream of a dipole magnet, and three stations placed...
ALICE (A Large Ion Collider Experiment) is the dedicated heavy–ion ex- periment at the CERN LHC designed to address the physics of strongly– interacting matter at extreme energy densities, where the formation of a deconfined phase of matter, the quark–gluon plasma (QGP), is expected. The innermost detector of ALICE is the Inner Tracking System (ITS), a six-layer silicon vertex detector that...
The phase-I upgrade of the Compact Muon Solenoid (CMS) pixel detector has been designed to maintain the tracking performance at instantaneous luminosities of 2 x 10^34 cm-2 s-1. Both barrel and endcap disk system now feature one extra layer (4 barrel layers and 3 endcap disks), and a digital readout that provides a large enough bandwidth to read out its 124M pixel channels (87.7% more pixels...
CCDs measure ionization energy produced from nuclear or electronic recoils, and can therefore be used as particle detectors with extremely low readout noise. This opens up a new experimental frontier in searching for coherent scattering of dark matter or neutrinos from silicon nuclei that produce ionization energies of only 10s of electron Volts. This talk will explain how CCDs are used for...
The CMS-TOTEM Precision Proton Spectrometer allows extending the LHC physics program by measuring the protons in the very forward regions of CMS. Tracking and timing detectors have been installed along the beam pipe at $\sim 210$ m from the CMS interaction point on both sides of the LHC tunnel. The tracking system consists of a station of silicon strip detectors and a station of silicon pixel...
The STAR PiXeL detector (HFT PXL) at RHIC is the first application of the thin Monolithic Active Pixel Sensors (MAPS) technology in a collider environment. It is based on 50 μm-thin MAPS sensors with a pitch of 20.7 μm. The sensor is read-out in rolling shutter mode in 185.6 μs. The 170 mW/cm2 power dissipation allows for air cooling and contributes to reducing the global material budget to...
