We are conducting an X-ray survey of the most massive clusters identified from the Deep Lens Survey (DLS). The DLS is a deep multicolor (BVRz') imaging survey of 28 square degrees being carried out at the 4-m telescopes of the US National Observatories (KPNO and CTIO). The DLS shear-selected cluster sample makes it possible for the first time to study clusters in a baryon-independent way. Nearly every DLS mass cluster observed by Chandra contains an X-ray cluster; their luminosities range from a few 1042 erg s-1 to nearly 1045 erg s-1. Most shear peaks contain multiple X-ray clusters, while the high mass clusters we detect are particularly complex with up to 4 or 5 individually resolved subcomponents. In this presentation we will report on the status of the first year of the survey. This work was partially supported by NASA grants NAG5-3432 and NAG5-13560 and Chandra grant GO3-4173A.
