MegaPrime operations
S. Gajadhar, K. Ho, J.C. Cuillandre

Abstract: An update of MegaPrime operations is provided. With improvements to the maintenance program, MegaPrime%92s reliability has improved over the last year. The last several runs have been free of technical problems. One issue that was addressed without loss of observing time was the degradation in sensitivity. The cause was identified as contamination of the camera window and the top of the ISU. Cleaning the optical surfaces has returned the sensitivity almost to 2003 levels. Collaboration with CEA continues on the cryogenic system, as well as with the SNDICE team on a photometric calibration project.,
