説明

The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan

At Kanazawa University, we started X-ray microcalorimeter experiments in 2007. We are now developing a compact adiabatic demagnetization refrigerator (ADR) to operate X-ray microcalorimeters. The ADR will be composed of two stages, so that it can achieve large cooling capacity with a reasonable size. So far, we fabricated the colder stage, which consists of a salt pill of ferric ammonium alum (FAA), a superconducting magnet, and a mechanical heat switch. We operated it in a dedicated cryostat for this experiment, and achieved approximately 100 mK.
