Abstract The High Resolution Dynamics Limb Sounder (HIRDLS) Cooler Subsystem provides 62 K cooling to the detector subsystem using a cryocooler symmetrically supported in a heat-rejecting radiator. The electronics, with software, is mounted on an independent panel of the instrument structure. Detail design of the cooler subsystem is underway, following the instrument system configuration trade studies and the instrument preliminary design review. The technical challenges associated with vibration cancellation are compounded by the necessity to simultaneously reject heat from the system. We discuss our system layout and how we provide active vibration cancellation while providing thermal system compatibility and isolation. We discuss the flexible vacuum enclosure and orthogonal bellows, which provide omnidirectional and low-interface forces during instrument integration and alignment. The enclosure also provides a vacuum environment for ground testing. We discuss the cooler-to-detector interface with the Ball S-link, which is highly conductive and compliant.1 We discuss the electronics reliability and strategic redundancy implemented in its circuitry to assure the highest reliability versus cost and weight. We also discuss the software implementation.
