Description
The ATLAS Experiment uses a two-level triggering system to identify and
record collision events containing a wide variety of physics signatures.
It reduces the event rate from the bunch-crossing rate of 40 MHz to an
average recording rate of 1 kHz, whilst maintaining high efficiency for
interesting collision events. It is composed of an initial
hardware-based level-1 trigger followed by a software-based high-level
trigger. A central component of the high-level trigger is the
calorimeter trigger. This is responsible for processing data from the
electromagnetic and hadronic calorimeters in order to identify
electrons, photons, taus, jets and missing transverse energy. In this
talk I will present the performance of the high-level calorimeter
trigger in Run-2, noting the improvements that have been made in
response to the challenges of operating at high luminosity.
