The CAMISTIC project aims to install a filled bolometer-array camera with 16x16 pixels on a small telescope (e.g. IRAIT) at Dome C and open the 200-μm (i.e. THz) windows for ground-based observations. CAMISTIC will be located at about 500 m from the base, with very reduced access. Autonomous and automated cryogenic devices specifically designed for the harsh conditions in Antarctica will therefore be needed. We plan to demonstrate the reliability of a novel cryogenic system with all static parts placed next to cryostat at outer temperature conditions and a warmed cabinet for compressors, motors and valves. Extensive tests in wintering condition will be performed before expedition. CAMISTIC will be equipped with novel bolometer technology. The filled bolometer array with a monolithic grid of 256 pixels was designed by CEA for the PACS far-IR/submm imager on the Herschel Space Observatory and similar arrays are currently developed for the ArTéMiS submm camera on ground-based telescopes. A prototype camera operating in the 450 μm atmospheric window has successfully been tested in March 2006 on the KOSMA telescope. CAMISTIC will perform site testing on the atmospheric opacity and sky noise at 200-450 μm and then open the way for future, large submm telescopes at Dome C. In the future, placed on a 12-m single-dish telescope at Dome C, a bolometer camera with ~10000 pixels at 200-450 μm will be particularly powerful to undertake wide field surveys of star-forming complexes in our Galaxy as well as deep field surveys of dust-enshrouded high-redshift galaxies in the early Universe.
