Level-1 Trigger Systems for LHC Experiments

  • Francesca Pastore
Conference paper

Abstract

The Large Hadron Collider (LHC) at CERN is expected to collide proton bunches at a rate of 40 MHz. The challenge of the first level trigger systems of the LHC experiments is to reduce the original collision rate by a factor of O(1000) with dedicated hardware trigger systems. Robustness of the systems and fine tuning of their parameters are needed to reach these requirements. In this paper the ATLAS and CMS Level-1 systems are presented, with the purpose of describing the current status of studies on the performance of each subsystem, the tuning of the configuration parameters and the trigger menus. Both systems are currently under the commissioning phase.
