Description

The High-Luminosity LHC is the Large Hadron Collider long term program targeting to operate the accelerating machine at the instantaneous luminosity of 7.5 x 10^34 cm^-2 s^-1, corresponding to approximately 200 pp interactions per bunch-crossing. The ATLAS Trigger System will be upgraded to cope with such a high rate of incoming particles. The ATLAS collaboration has endorsed a upgraded trigger architecture design based on a single Level-0 hardware trigger using calorimeter and muon spectrometer information with an output readout rate of 1 MHz and a maximum latency of 10 μs, followed by an Event Filter software system, delivering an output rate of 10 kHz to the permanent storage. The status of the design and test of the upgraded system will be presented, with a focus on the upgrade of the Muon Trigger subsystem.
