Level-1 Regional Calorimeter Trigger System for CMS
The Compact Muon Solenoid (CMS) calorimeter regional trigger system is designed to detect signatures of isolated and nonisolated electrons/photons, jets, τ-leptons, and missing and total transverse energy using a deadtimeless pipelined architecture. This system contains 18 crates of custom-built electronics. The pre-production prototype backplane, boards, links and Application-Specific Integrat...

The CMS calorimeter regional trigger system is designed to detect signatures of isolated and non-isolated electrons/photons, jets, τs, and missing and total transverse energy using deadtimeless pipelined architecture. This system comprises of 18 crates of custom-built electronics. The pre-production prototype backplane, boards, links and ASICs have been built and their performance is characteri...
متن کاملCMS REGIONAL CALORIMETER TRIGGER HIGH SPEED ASICs
The CMS regional calorimeter trigger system detects signatures of electrons/photons, taus, jets, and missing and total transverse energy in a deadtimeless pipelined architecture. This system contains 20 crates of custombuilt electronics. Much of the processing in this system is performed by five types of 160 MHz digital ASICs. These ASICs have been designed in the Vitesse submicron highintegrat...
متن کاملCms Calorimeter Trigger Implementation and Performance
For most of the CMS ECAL, a 6 crystal by 6 crystal array of physical calorimeter towers is mapped into trigger towers. There is a 1:1 correspondence between the HCAL and ECAL trigger towers. The trigger tower size is equivalent to the HCAL physical towers, .087 x .087 in η x φ. The φ size remains constant in ∆φ and the η size remains constant in ∆η out to an η of 2.1, beyond which the η size do...
متن کاملCMS Calorimeter Trigger/Readout Electronics for SLHC
The SLHC will be a very challenging environment for physics and for the trigger and DAQ in particular. Expected pileup multiplicies on the level of 40-200 interactions every beam crossing will flood the detector with the “ambient noise” of many low pT particles. The impact of these low pT particles is particular large for the hadron calorimeter, which has a relatively large cell size (compared ...
