Abstract
Developing a cooling method of far-infrared detectors in micro-gravity circumstances in the 0.1 K region, we have designed a new adiabatic demagnetization cryostat and improved a fabrication method of magnetic salt. The cryostat was designed for laboratory use (under 1 G), however most thermal conditions were planned for use in space. An optical window was prepared for the real combination with detector element. The measured heat leak was about 130 mW which enabled us to operate the cryostat more than 50 hours. Low operating current superconducting magnet which was indirectly cooled by liquid helium, was mounted on the cryostat. The magnetic field of 3 T was obtained by current of 11.5 A. The success of the magnet guaranteed the system to work in space where fluid interfaces are not clear. Manganese ammonium alum was grown from the saturated solution and purified.
