note = {This dissertation presents a search for long-lived, multi-charged particles using the ATLAS detector at the LHC. Motivation for this search arose from an unexploited search regime at ATLAS of stable massive particles with electric charges of |q| = 2e to |q| = 5e. Additional motivation can be found in several beyond the Standard Model physics theories. Proton-proton collisions recorded during the 2011 LHC running at sqrt(s) = 7 TeV, corresponding to an integrated luminosity of 4.4 fb−1, are examined in a signature-based analysis. The search seeks out charged particle tracks exhibiting anomalously high ionization consistent with stable massive particles with electric charges in the range from |q| = 2e to |q| = 6e. For this search, new variables of specific energy loss per path length dE/dx are used in the candidate selection. One of these variables, the TRT dE/dx, is developed in the course of this thesis and is described in detail. No excess is observed with respect to the prediction of Standard Model processes. The 95% C.L. upper cross section limits are also interpreted as mass exclusion limits for a simplified Drell-Yan production model.},
