Abstract This report summarizes the activities of the Haystack Correlator during 2011. Highlights include acquisition of new hardware for a DiFX cluster, development and improvement of tools to facilitate DiFX production, more u-VLBI Galactic Center observations, Mark 6 recording system testing, and various other continuing projects. Non-real-time e-VLBI transfers and engineering support of other correlators continued. The Mark IV and DiFX VLBI correlators of the MIT Haystack Observatory, located in Westford, Massachusetts, are supported by the NASA Space Geodesy Program and the National Science Foundation. They are dedicated mainly to the pursuits of the IVS, with a smaller fraction of time allocated to processing radio astronomy observations for the Ultra High Sensitivity VLBI (u-VLBI) project. The Haystack correlators serve as a development system for testing new correlation modes, for hardware improvements such as the Mark 6 system, and in the case of the Mark IV, for diagnosing correlator problems encountered at Haystack and at the identical correlator at the U.S. Naval Observatory. This flexibility is made possible by the presence on-site of the team that designed the Mark IV correlator hardware and software. Some software support is provided to the Max Planck Institute for Radioastronomy (MPI) in Bonn, Germany for DiFX processing of IVS experiments.
