Abstract
SCUBA-2 has been operational on JCMT producing excellent science for almost 5 years. We describe the strategy and methods that we have evolved to keep one of the world’s first “dry dilution refrigerators” and the other cryogenic systems working effectively at the summit of Mauna Kea, keeping the instrument functioning at peak efficiency for extended periods (over 12 months at a time), with minimum downtime. We discuss new plans to reduce day-to-day operational costs and to add remote management of the gas handling systems, as we look to the future and envisage another ten years of SCUBA-2 science.
