摘要：

Dark matter is a type of matter hypothesized in astronomy and cosmology to account for a large part of the mass that appears to be missing from the universe. China Dark matter EXperiment (CDEX) is a direct detection system of dark matter. A cryogenic system for CDEX-10 has been designed and constructed. This note describes the cryogenic system of the CDEX-10, theoretical predictions of the heat loads to the cryostat, and measured heat loads at operation. The cryostat is an argon cooled bath type cryostat. Two pulse tube refrigerators are used for argon liquefying. The dark matter detecting needs a very quiet condition, so a special thermal shield is designed to reduce the radiation heat leakage. (C) 2016 Elsevier Ltd. All rights reserved.
