For the Phase-II Upgrade of ATLAS Detector [1], its Inner Detector, consisting silicon pixel, strip and transition radiation sub-detectors, will be replaced with an all new 100% tracker, composed a pixel tracker at inner radii outer radii. The future include 11,000 sensor modules in central region (barrel) 7,000 forward (end-caps), which are foreseen to constructed over period 3.5 years. construction each module consists series assembly quality control steps, were engineered identical for...
A network of 16 Medipix-2 (MPX) silicon pixel devices was installed in the ATLAS detector cavern at CERN. It designed to measure composition and spectral characteristics radiation field experiment its surroundings. This study demonstrates that MPX can also be used as a self-sufficient luminosity monitoring system. The detectors collect data independently data-recording chain, thus they provide independent measurements bunch-integrated ATLAS/LHC luminosity. In particular, located close enough...
A hybrid silicon pixelated TIMEPIX detector (256 × 256 square pixels with a pitch of 55 μm) operated in Time Over Threshold (TOT) mode was exposed to radioactive sources and protons after Rutherford Backscattering on thin gold foil beams delivered by the Tandem Accelerator Montreal University. Simultaneous exposure top allowed measurements different mixed radiation fields protons, alpha-particles, photons electrons. All were performed vacuum. The comparison experimental activities...
The use of tracking information at the trigger level in LHC Run II period is crucial for and data acquisition system will be even more so as contemporary collisions that occur every bunch crossing increase III. Fast TracKer part ATLAS upgrade project; it a hardware processor provide Level-1 accepted event (100 kHz) within 100μs, full tracks with momentum low 1 GeV . Providing fast, extensive access to information, resolution comparable offline reconstruction, FTK help precise detection...
A luminosity determination based on thermal neutron counting with six MPX silicon pixel devices installed in the ATLAS cavern is presented. Recently, Collaboration published final √s=8 TeV results. This made possible to perform a detailed comparison and verify potential of as novel method for measurements supplement well-established presently used procedures. measurement unique network has advantage that neutrons, which pass devices, cannot result from activation processes material nearby....

The ATLAS Fast TracKer(FTK) is a custom hardware system for fast, associative memory based track reconstruction. It will provide tracking information within the full acceptance of inner detectors to High Level Trigger at rate up 100 kHz. At first stage FTK, Data Formatter subsystem clusters detector hits and organizes them into 64 $\eta$-$\phi$ trigger regions. last stage, FTK HLT interface cards repackage records send computing farm. This report aims give an overview over functionality two...
