118. The Sector Collector of the CMS DT Trigger System: Installation and Performance

Dr Riccardo Travaglini (Dipartimento di Fisica-INFN Bologna-Italy)

Oral

Drift Tubes chambers are used for muon detection in the central region of the CMS experiment at LHC. Custom electronics is used for reconstructing muon track segments and for triggering the CMS readout. The trigger Sector Collector modules collect muon segments identified by the on-chamber devices, synchronize the data received from different chambers and convert from LVDS to Optical for...

52. The commissioning status and results of ATLAS Level1 Endcap Muon Trigger System

Mr Yasuyuki Okumura (Nagoya University)

Oral

The ATLAS Level1 endcap muon trigger selects interesting events containing muons with Pt greater than 6GeV/c from 40MHz proton-proton collisions. This system consists of 3,600 Thin Gap Chambers (TGCs) and the total number of readout channels is 320,000. This trigger logic is based on the coincidence between 7 layers of TGCs. All processes are performed on fast electronics within 2.5 micro...

8. Level-3 Calorimeter Resolutions Available for the Level-1 and Level-2 CDF Triggers.

Oral

As the Tevatron luminosity increases more sophisticated selections are required to be efficient in selecting rare events from a very huge background. To cope with this problem, CDF has pushed the level 3 calorimeter algorithm resolutions up to Level 2 and, when possible, even at Level 1, increasing efficiency and, at the same time, keeping under control the rates. This strategy increases...

136. Commissioning of the ATLAS Level-1 Central Trigger system

Andrea Messina (Conseil Europeen Recherche Nucl. (CERN)-Unknown-Unknown)

19/09/2008, 10:15

Oral

The ATLAS Level-1 Central Trigger (L1CT) consists of the Central Trigger Process (CTP) and the Muon to Central Trigger Processor Interface (MuCTPI). The CTP forms the final Level-1 Accept (L1A) decision based on the information received from the Level-1 Calorimeter Trigger system and from the muon trigger system through the MuCTPI. Additional inputs are provided for the forward...

6. Modular Trigger Processing - The GCT Muon/Quiet bit System and future applications

Mr Matt Stettler (CERN)

19/09/2008, 10:40

Oral

The CMS Global Calorimeter Trigger HCAL Muon and Quiet bit processing function is being implemented with a micro TCA system. This system is reconfigurable in both logical functionality and data flow, allowing great flexibility to meet processing requirements. The system consists of a processing module based on a Xilinx Virtex 5 FPGA and custom backplane based on a Mindspeed crosspoint switch....
