Description
The experience gained during the first period of very successful data
taking of the ATLAS experiment (Run I) has inspired a number of ideas
for improvement of the Data AcQuisition (DAQ) system that are being
put in place during the so-called Long Shutdown 1 of the Large Hadron
Collider (LHC), in 2013/14. We have updated the data-flow
architecture, rewritten an important fraction of the software and
replaced hardware, profiting from state of the art technologies.
This paper summarizes the main changes that have been applied to the
ATLAS DAQ system and highlights the expected performance and
functional improvements that will be available for the LHC Run
II. Particular emphasis will be put on explaining the reasons for our
architectural and technical choices, as well as on the simulation and
testing approach used to validate this system.
