ATLAS Experiment: one year to go till Run 3

ATLAS detector has been undergoing maintenance and improvement work since early 2019. One of the main improvements on the way is a ten-fold increase in the granularity of the calorimeter trigger, which leads to a better selection of events with electrons and photons present in a wide variety of processes at the LHC.

Since 2012, the ATLAS LAPP team worked on one of the critical components for this upgrade: an electronic board called "LATOME", which calculates energy and time of the signals provided to the trigger.

In March 2021, all 116 LATOMEs required for collection of the ATLAS data have been finally installed in the ATCA crates in the electronics room, 100 meters below the ground, next to the detector.

The team will use the coming months to ensure the correct functioning of these boards and their integration into the ATLAS readout system to be ready for the LHC pilot run in October 2021 and the start of the Run 3 data-taking in March 2022.
