Teaching buy-out to coordinate the data taking activities of the ATLAS experiment

To study the physics of elementary particles the conditions which governed the universe at its beginning are reproduced in collider experiments: The Large Hadron Collider (LHC) has been build at CERN, a particle accelerator which probes deeper into the processes of the Big Bang than ever before. In 2008 it started to collide beams of protons, and collected data-sets at 7 and 8 TeV centre-of-mass energy that enabled the discovery of the Higgs particle in 2012, which lead to the attribution of the 2013 Noble price in Physics to Francois Englert and Peter Higgs. The LHC resumed operation in 2015 at nearly twice the collision energy, and first results presented in December 2015 have sparked excitement amongst scientist about the possibility of physics not described by the Standard Model of particle physics.Ultimately, LHC will need to deliver more collisions to have a decisive answer if the results presented in December 2015 were the first indication of new physics or a statistical fluctuation. LHC is preparing to produce up to 20 times the number of collision in the run-2 period during the next 2 years, and the ATLAS experiment is preparing to take data with the highest possible efficiency.In October 2015 AO was elected to become the next "Run Coordinator" of the ATLAS experiment by thecollaboration board, representing the 174 collaborating institutes and about 3000 scientists.The prestigious "Run Coordinator" role is a position of high responsibility and visibility, with the mandate to coordinate the operation of the entire ATLAS experiment. It is the mandate of the Run Coordinator to supervise and ensure the continuous and efficient operation of the ATLAS detector.
