114. The Level 0 Pixel Trigger System for the ALICE Silicon Pixel Detector: implementation, testing and commissioning.

Dr Gianluca Aglieri Rinella (CERN)

16/09/2008, 10:10

Oral

The ALICE Silicon Pixel Detector transmits 1200 Fast-OR signals every 100 ns using its 120 optical readout channels. They indicate the presence of at least one hit in the pixel matrix of each readout chip. The ALICE Level 0 Pixel Trigger system extracts, processes them and delivers an input signal to the Central Trigger processor for the first level trigger decision within a latency of...

68. First results on the performance of the CMS Global Calorimeter Trigger

Dr Gregory Michiel Iles (Imperial College)

16/09/2008, 11:00

Oral

The CMS Global Calorimeter Trigger (GCT) has been designed, manufactured and commissioned on a short time schedule of approximately two years. The GCT system has gone through extensive testing on the bench and in-situ and its performance is well understood. This paper describes problems encountered during the project, the solutions to them and possible lessons for future designs, particularly...

116. Operation and Monitoring of the CMS Regional Calorimeter Trigger

Mrs Pamela Klabbers (University of Wisconsin)

16/09/2008, 11:25

Oral

The electronics for the Regional Calorimeter Trigger (RCT) of the Compact Muon Solenoid Experiment (CMS) have been produced, tested, and installed. The RCT hardware consists of 1 clock distribution crate and 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)...

39. Analysis of the initial performance of the ATLAS Level-1 Calorimeter Trigger

Dr Damien Prieur (STFC, Rutherford Appleton Laboratory)

16/09/2008, 11:50

Oral

The ATLAS first-level calorimeter trigger is a hardware-based system designed to identify high-pT jets, electron/photon and tau candidates and to measure total and missing ET in the calorimeters. The installation of the full system of custom modules, crates and cables was completed in late 2007, but, even before the completion, it was being used as a trigger during ATLAS commissioning and...

26. Digital signal integrity and stability in the ATLAS Level-1 Calorimeter Trigger

Ms Andrea Neusiedl (University of Mainz)

16/09/2008, 12:15

Oral

The ATLAS first-level calorimeter trigger is a hardware-based system designed to identify high-pT jets, electron/photon and tau candidates and to measure total and missing ET in the ATLAS calorimeters. Apart from the initial analogue stage, the trigger system consists of a multi-stage pipelined digital processor distributed over several crates of custom-built modules. The high demands for...
