Intergalactic stellar populations and tidal debris are now recognized as important components of galaxy clusters. This project examines the interrelated processes of galaxy destruction, recycling of tidal debris, and creation of dwarf galaxies and intergalactic star clusters, all of which are part of the grand scheme of cluster formation. We propose deep multicolor imaging of two examples of newly created tidal debris, the spectacular plumes in the Centaurus and Coma clusters. The Centaurus observations will extend our earlier work, which demonstrated the existence of tidal debris dwarf galaxies and star cluster in the body of the Centaurus plume. Deep ACS/WFC observations can determine rough ages and cluster membership, better characterizing the new debris. The Coma observations will reproduce this work for a second plume feature, in the quintessential rich cluster of galaxies. Parallel WFPC2 observations will investigate the central intracluster spaces at the bottom of the each cluster's potential, where older debris is thickest.
