Astr., Phys, & Geo-University of Copenhagen The Upgrade of the ATLAS Level-1 Central Trigger Processor 2012 CERN Geneva 17 Sep 2012 16 p SLIDES The ATLAS Level-1 Central Trigger Processor (CTP) combines information from calorimeter and muon trigger processors as well as other sources and makes the final Level-1 Accept (L1A) decision. Due to the increasing luminosity of the LHC and the growing demands of physics and monitoring placed on the ATLAS Level-1 trigger system, the current CTP has reached its design limits. Therefore and in order to provide some margin for future operation, the CTP will be upgraded during the LHC shutdown of 2013/14.
