摘要：

An overview is given of the general principles and techniques used for the design and construction of compact, portable adiabatic demagnetization refrigerators (ADRs). The paper covers methods of salt pill suspension, magnet technology, lead design, heat switches and temperature readouts, as well as considerations for space qualification. Performance specifications are given for an ADR which was originally developed for cooling infrared detectors on the Space Infrared Telescope Facility (SIRTF). This ADR is presently used on the balloon-borne Millimeter Wave Anisotropy Experiment (MAX) for measuring anisotropy in the cosmic microwave background. Comparisons are made with other ADRs under development for use in space or on rockets.
