54. Integration of the CMS regional calorimeter Trigger hardware into the CMS level-1 Trigger

Pamela Klabbers (University of Wisconsin)

9/26/06, 10:55 AM

Oral

The electronics for the Regional Calorimeter Trigger (RCT) of the Compact Muon Solenoid Experiment (CMS) have been produced and tested. The RCT hardware consists of 18 double-sided crates containing custom boards, ASICs, and backplanes. The RCT receives 8 bit energies and a data quality bit from the HCAL and ECAL Trigger Primitive Generators (TPGs) and sends it to the CMS...

75. Revised CMS Global Calorimeter Trigger Hardware Design

Matt Stettler (CERN)

9/26/06, 11:20 AM

Oral

An alternative design for the CMS Global Calorimeter Trigger (GCT) is being implemented. The new design adheres to all the CMS specifications regarding interfaces and functional requirements of the trigger systems. The design is modular, compact, and utilizes proven components. Functionality has been partitioned to allow commissioning in stages corresponding to the different...

72. The Drift Tube Track Finder Muon Trigger at the CMS Experiment

Jorge Fernandez De Troconiz (Universidad Autonoma de Madrid)

9/26/06, 11:45 AM

Oral

The Compact Muon Solenoid (CMS) is a general purpose experiment designed to study proton-proton collisions at the Large Hadron Collider (LHC). At the LHC, proton beams will cross each other at a rate of 40 MHz, producing in average 20 p-p interactions. The CMS L1 Trigger must select interesting collisions at a rate smaller than 100 kHz. The Drift Tube Track Finder (DTTF) implements the...

11. An RPC-based Technical Trigger for the CMS Experiment

Flavio Loddo (INFN Bari)

9/26/06, 12:10 PM

Oral

In the CMS experiment, sub-detectors may send special trigger signals, called “Technical Triggers”, for special purposes like test and calibration during the off-beam periods. The Resistive Plate Chambers are part of the Muon Trigger System of the experiment, but might also be used to produce a cosmic muon trigger as Technical Trigger to be used during the Cosmic Challenge and the later...

43. Design and Test of the Off-Detector Electronics for the CMS Barrel Muon Trigger

Luigi Guiducci (Istituto Nazionale di Fisica Nucleare (INFN))

9/26/06, 12:35 PM

Oral

Drift Tubes chambers are used in the CMS barrel for tagging the passage of high Pt muons generated in a LHC event and for triggering the CMS data read out. The Sector Collector system synchronizes the track segments built by trigger modules on the chambers and deliver them to reconstruction processors (Track Finder, TF) that assemble full muon tracks. Then, the Muon Sorter has to...
