This paper reports on studies of the initial performance of the ATLAS detector from these data. Comparisons between data and Monte Carlo predictions are shown for distributions of several track- and calorimeter-based quantities. The good performance of the ATLAS detector in these first data gives confidence for successful running at higher energies. %K Hadron-Hadron Scattering %R 10.1007/JHEP09(2010)056 %U http://arXiv.org/abs/1005.5254 %U https://doi.org/10.1007/JHEP09(2010)056 %P 056-66pp
