Abstract

MegaCam has been CFHT's one-degree wide-field optical imager and primary dark time instrument since 2003. After nearly twenty years of operation, demand for the instrument remains high, but maintenance has been a challenge as many electronic components have become obsolete and difficult to find. Other off-the-shelf assemblies, such as the S-LINK data transmission pair for the CCD controllers from CERN (European Organization for Nuclear Research), are also no longer available and cannot be repaired. Ongoing failures, only one working spare, and a lack of a plug-n-play upgrade path forced the development of an alternative solution.
