DECam Engineering Schedule

DECam is presently in a scheduled engineering shutdown. During these two weeks improvements are being made to most of the systems associated with the instrument. For instance, the cooling system for the prime focus cage electronics is being hardened by plumbing in a complete spare chiller than will allow rapid changeover in case of a pump failure, the liquid nitrogen pumping system is being placed on a devoted UPS and the controller changed to allow this, the calibration unit (DECal) is having a software upgrade, and there are improvements to the telemetry that will better allow us to monitor instrument performance, amongst a host of other changes.
