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...

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...

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)...

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...

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...
