Oral

The Level-0 Decision Unit (L0DU) is the central part of the first trigger level of the LHCb detector. The L0DU receives information from the Calorimeter, Muon and Pile- Up sub-triggers at 40 MHz via 24 high speed optical fiber links running at 1.6 Gb/s. The L0DU performs simple physical algorithm to compute the decision in order to reduce the data flow down to 1 MHz for the next trigger...

Oral

The Level-0 muon trigger looks for straight tracks crossing the five muon stations of the muon detector and measures their transverse momentum. The tracking uses a road algorithm relying on the projectivity of the muon detector. The Level-0 muon trigger analyzes every LHC bunch crossing. It handles about 130 GBytes per second. It finds muon tracks for a bunch crossing in about one...

4. LHCb Calorimeter Trigger : Validation Board

Cyril Drancourt (Laboratoire d'Annecy-le-Vieux de Physique des Particules (LAPP))

Oral

The Validation board participates in the electronic for triggering system of LHCb calorimeter detector. The board, designed in Annecy-le-vieux Laboratory (LAPP-France), has logic radiation tolerant components: programmable logic, LVDS deserializer, 1.6Gbits optic transmitter. The inputs come from Front-end board of 4 different detectors (Electromagnetic, Hadronic, PreShower,...

97. Installation and Test of the ATLAS Muon Endcap Trigger Chamber Electronics

Hiroshi Nomoto (ICEPP,Tokyo)

Oral

For the detector commissioning planned in 2007, a sector assembly of the ATLAS muon endcap trigger chambers is progressed in CERN intensively. Final technical test for the electronics mounted on a sector must be accomplished at this stage. For systematic test of the electronics, we have developed a DAQ system on top of the ATLAS online software framework. The system is not dedicated only...
