Abstract
Abstract
The Phase-I trigger readout electronics upgrade of the ATLAS
Liquid Argon calorimeters enhances the
physics reach of the experiment during the upcoming operation at
increasing Large Hadron Collider luminosities.
The new system, installed during the second Large Hadron Collider Long Shutdown,
increases the trigger readout granularity by up to a factor of ten
as well as its precision and range.
Consequently, the background rejection at trigger level is improved
through enhanced filtering algorithms utilizing the additional information
for topological discrimination of electromagnetic and hadronic shower shapes.
This paper presents the final designs of the new electronic elements,
their custom electronic devices, the procedures
used to validate their proper functioning, and the performance achieved
during the commissioning of this system.
