Plans for checking hadronic energy depositions in the ATLAS calorimeters with early LHC data using charged particles

The first data from the ATLAS detector at the Large Hadron Collider (LHC) is due to be collected later this year. This first phase will play a vital role in understanding the detector and its response, in-situ. Jet reconstruction is important for identifying new physics as well as making precision measurements of standard model physics. The fine granularity of the ATLAS calorimeters can be used to gain information about a jet's shape and the classification of energy deposits, which allows a better estimate of the jet energy to be made and in particular correction for the non-compensating nature of the calorimeter using so-called calibration weights. The classification algorithm and weights are presently calculated using simulation. In this presentation we describe an important step in the validation of ATLAS's jet calibration using charged tracks reconstructed in the inner detector and their inter-calibration with the clusters reconstructed in the calorimeters.
