The uncertainty on the calorimeter energy re- sponse to jets of particles is derived for the ATLAS ex- periment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation us- ing proton-proton collisions at centre-of-mass energies of vs = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using the decay of Ks and ? particles, the calorimeter response to specific types of particles (positively and nega- tively charged pions, protons, and anti-protons) is measured and compared to the Monte Carlo predictions. Finally, the jet energy scale uncertainty is determined by propagating the response uncertainty for single charged and neutral par- ticles to jets. The response uncertainty is 2–5 % for central isolated hadrons and 1–3 % for the final calorimeter jet en- ergy scale.
