476. ATLAS Tile calorimeter calibration and monitoring systems

Marija Marjanovic (Univ. Blaise Pascal Clermont-Fe. II (FR))

11/06/2018, 13:00

Oral presentation

The ATLAS Tile Calorimeter (TileCal) is the central section of the hadronic calorimeter of the ATLAS experiment. This sampling calorimeter uses steel plates as absorber and scintillating tiles as active medium. The light produced by the passage of charged particles is transmitted by wavelength shifting fibers to photo-multiplier tubes (PMTs), located in the outer part of the calorimeter. The...

454. Online track reconstruction on GPUs for the Mu3e and LHCb experiments

Dorothea Vom Bruch (Centre National de la Recherche Scientifique (FR))

11/06/2018, 13:20

Oral presentation

As the data rate produced by modern particle physics experiments increases, the demands on the computing performance of data selection processes grow. Therefore, Graphics Processing Units (GPUs) are being considered for this task. This talk focuses on their use in the online event selection for the Mu3e experiment and within studies of track reconstruction for the LHCb experiment.

The Mu3e...

565. Vertical Slice System Demonstration of a Tracking Trigger using an Associative Memory Approach

Zhen Hu (Fermi National Accelerator Lab. (US))

11/06/2018, 13:40

Oral presentation

It has become evident that the development of a Level 1 tracking trigger system is crucial for the success of the HL-LHC physics program at the CMS experiment. The high pile-up and high occupancy conditions anticipate an input data rate into the tracking trigger system of ~100 Tbps. This, combined with the 4 s latency required the L1 track finding trigger stage introduce an unprecedented set...

441. The Phase-1 Upgrade of the ATLAS Level-1 Endcap Muon Trigger

Shunichi Akatsuka (Kyoto University (JP))

11/06/2018, 14:00

Oral presentation

The LHC is expected to increase its instantaneous luminosity to 3.0 × 10^34
cm^(-2)s^(-1) after the 'Phase-1' upgrade scheduled from 2019 to 2020. In order to cope with the high luminosity, an upgrade of the ATLAS trigger system is required. The level-1 Endcap Muon trigger system identifies muons with high transverse momentum by combining data from a fast muon trigger detector, TGC, and some...

509. Streaming Readout of the sPHENIX Tracking System

M. L. Purschke, for the sPHENIX collaboration

11/06/2018, 14:20

Oral presentation

The sPHENIX Collaboration at RHIC is upgrading the PHENIX detector in
a way that will enable a comprehensive measurement of jets in
relativistic heavy ion collisions. The upgrade will give the
experiment full azimuthal coverage within a pseudorapidity range of
$-1.1 < \eta < 1.1$.

Since the last conference, we have make significant progress with the
readout of our calorimeters, which work...
