Performance of the ATLAS Detector in Run-2

Performance of the ATLAS Detector in Run-2

The second LHC run has started in June 2015 with a p-p center-of-mass collision energy of 13 TeV and ATLAS has taken 3.2 fb-1 of data at the new energy in 2015. In this talk the improvements made to the ATLAS experiment during the two-year shutdown 2013/2014 will be discussed. Furthermore, reconstru...
