70. Commissioning of the ATLAS Level-1 Central Trigger

Thilo Pauly (European Organization for Nuclear Research (CERN))

Oral

The ATLAS Level-1 Central Trigger consists of the Central Trigger Processor (CTP) and the Muon to Central Trigger Processor Interface (MuCTPI). The CTP receives trigger information from the Level-1 Calorimeter Trigger system directly, and from the Level-1 Muon Trigger systems through the MuCTPI. It also receives timing signals from the LHC machine, and fans out the Level-1 Accept signal,...

36. The Octant Module of the ATLAS Level-1 Muon to Central Trigger Processor Interface

Stefan Haas (CERN)

26/09/2006, 16:45

Oral

The Muon to Central Trigger Processor Interface (MUCTPI) of the ATLAS Level-1 trigger receives data from the sector logic modules of the muon trigger at every bunch crossing and calculates the total multiplicity of muon candidates, which is then sent to the Central Trigger Processor (CTP) where the final Level-1 decision is taken. The MUCTPI system consists of a 9U VME crate with a special...

84. The ATLAS Barrel Level-1 Muon Trigger Calibration

Riccardo Vari (Istituto Nazionale di Fisica Nucleare (INFN))

26/09/2006, 17:10

Oral

The ATLAS experiment uses a system of three concentric Resistive Plate Chambers detectors layers for the level-1 muon trigger in the air-core barrel toroid region. The trigger classifies muons within different programmable transverse momentum ranges, and tags the identified tracks with the corresponding bunch crossing number. The algorithm looks for hit coincidences within different...

18. ATLAS TDAQ RoI Builder and the Level 2 Supervisor system

Yuri ERMOLINE (MSU)

26/09/2006, 17:35

Oral

The ATLAS High Level Trigger (HLT) uses information from the hardware based Level 1 Trigger system to guide the retrieval of information from the readout system. The Level 1 Trigger elements (jet, electromagnetic, muon candidate, etc.) determine Regions of Interest (RoIs) that seed further trigger decisions. This paper describes the device - the RoI Builder - that collects these data...

95. Setup, tests and results for the ATLAS TileCal Read Out Driver production

Alberto Valero (Instituto de Fisica Corpuscular (IFIC) UV-CSIC)

26/09/2006, 18:00

Oral

The setup used in the production of the 38 TileCal Read Out Drivers (RODs) and the results are described. Firstly we will explain all the hardware and firmware changes done to the RODs in order to adapt them to the TileCal requirements. Then, we will describe the procedure to test the RODs and the obtained results.
