For the next run of LHC, ATLAS Level-1 trigger system will include topological information on objects from calorimeters and muon detectors. In order to supply coarse grained information, existing MUCTPI (Muon-to-Central-Trigger-Processor Interface) has been upgraded. The MIOCT (Muon Octant) module firmware then modified extract, encode send through electrical outputs. detectors be sent Topological Trigger Processor (L1Topo) MUCTPI-to-Level-1-Topological-Processor (MuCTPiToTopo) interface....

The ATLAS detector at the Large Hadron Collider (LHC) is designed to measure decay properties of high energetic particles produced in proton-proton collisions. During its first run, LHC collided proton bunches a frequency 20 MHz, and therefore required Trigger system efficiently select events down manageable event storage rate about 400 Hz. By 2015 instantaneous luminosity will be increased up 3×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...

To cope with the enhanced luminosity delivered by Large Hadron Collider from 2021 onwards, ATLAS experiment has planned several upgrades. The first level trigger based on calorimeter data will be upgraded to exploit fine-granularity readout using a new system of Feature EXtractors (FEXs, FPGA boards), each optimized different physics objects. This contribution is focused jet FEX. main challenges such board are input bandwidth up 3.1 Tbps, dense routing high-speed signals and power...

Particle physics experiments often comprise tracking detectors with areas of up to a few square meters. If spatial resolution the order 100μm and high-rate capability are required, Micro Pattern Gaseous Detectors (MPGD) cost-effective solution. However, construction large-area MPGDs is challenging, since tight fabrication tolerances have be met guarantee stable homogeneous performance. A precision granite table an automated 3-D positioning system attached laser sensor, both inside...

The ATLAS experiment has planned a major upgrade in view of the enhanced luminosity beam delivered by Large Hadron Collider (LHC) 2021. As part this, trigger at Level-1 based on calorimeter data will be upgraded to exploit fine-granularity readout using new system Feature Extractors (three total), which each uses different physics objects for selection. contribution focusses jet EXtractor (jFEX) prototype. Up volume 2 TB/s processed provide identification (including large area jets) and...

To cope with the expected increase in luminosity at Large Hadron Collider 2021, ATLAS collaboration is planning a major detector upgrade to be installed during Long Shutdown 2. As part of this, Level-1 trigger based on calorimeter data, will upgraded exploit fine granularity readout using new system Feature EXtractors (FEXs), which each reconstruct different physics objects for selection. The jet FEX (jFEX) has been conceived identify small/large area jets, large tau leptons, missing...

After the Long Shutdown 2 (Dec.~2018 -- Feb.~2021), LHC will be a new machine in many respects and produce collisions with center-of-mass energy at or near 14 TeV. The instantaneous luminosities can expected to reach $2\times10^{34}$ cm$^{-2}$s$^{-1}$, which is two times original design value. mean number of interactions per bunch crossing go up 80. To meet challenges high-luminosity environment (much higher event rates pileup level), several major upgrades installed during ATLAS detector....
