If a model such as split-SUSY is realized in nature, R-hadrons, which contain a long-lived gluino or squark, can be produced and detected by the ATLAS experiments at the CERN Large Hadron Collider. These particles will traverse the detector and may lose enough of their energy through ionization to become captured and stop in the densest materials. Such "stopped" particles would decay at some later time, producing a high energy deposit which can be picked up by the trigger and detector, provided they remain active. This presentation discusses the detailed detector simulation, trigger strategy and analysis methods for detecting these stopped long-lived particles in ATLAS. We present a first study of the data collected with ATLAS at 7TeV center of mass energy.
