Configuration and control of the ATLAS trigger and data acquisition
ATLAS is a general purpose experiment aimed at studying high-energy particle interactions at the Large Hadron Collider (LHC). This paper describes the evolution of the Controls and Configuration system of the ATLAS Trigger and Data Acquisition from the Technical Design Report to the first events taken with circulating beams. We present the lessons learned during the development.
- Live Trial needs a lot of preparation and coordination with all stakeholders compared to real time simulation - An increase in situation awareness but also an increase in workload, a training effect is an important explanation but the use of new system can increase the ATCOs workload - AGL automatic switching of single lamp is the best solution to avoid segments issues faced at RIGA - D-TAXI transmission technology using 4G airport network can be a better solution than ATN for the issue of delay of transmission (security issue are also tackled by the use of new technology) - ATCOs think that D-TAXI can reduce situation awareness but associated with AGL, the global situation awareness can be improved - Using D-TAXI and AGL can improve safety at airport
