Progress in fields such as astronomy and fundamental physics requires increasingly complex instrumentation operating at millikelvin temperatures. Such instruments often place demands on materials and components not seen previously, particularly for space-based applications. The large scale of these projects and tight timescales necessitate the most conservative design possible. However, building these instruments with conventional techniques and materials is often impractical and sometimes impossible. It is therefore common for the design stage of such instruments to include test and measurement programs. These programs add risk to the development schedule, and suffer from the problem of tight focus on the exact needs of one particular instrument. We are setting up a laboratory to measure material properties and develop cryogenic components for general use in future large millikelvin instruments. By decoupling these measurements from a particular instrument program, we have the freedom to make more speculative measurements, such as measuring new polymers whose cryogenic properties are completely unknown. We describe our set-up, plans for the future, and results of initial measurements.
