Description
To cope with the increase of the LHC instantaneous luminosity, new
trigger readout electronics were installed on the ATLAS Liquid Argon
Calorimeters.
On the detector, 124 new electronic boards digitise at high speed 10
times more signals than the legacy system. Downstream, large FPGAs are
processing up to 20 Tbps of data to compute the deposited energies.
Moreover, a new control and monitoring infrastructure has been
developed.
This contribution will present the challenges of the commissioning, the
first steps in operation, and the milestones still to be completed
towards the full operation of both the legacy and the new trigger
readout paths for the LHC Run-3.
