A Miniature Adiabatic Demagnetization Refrigerator with a Magnetoresistive Heat Switch
نویسندگان
چکیده
We present the design of a novel, miniature ADR with no moving parts, which could be used to cool detectors for astrophysics research, semiconductor analysis, and mass spectrometry. The miniature ADR relies on the development of a magnetoresistive heat switch. We present measurements of the thermal conductivity of a single-crystal tungsten heat switch at temperatures below 4 K and magnetic fields below 0.9 Tesla.

Construction techniques for adiabatic demagnetization refrigerators using ferric ammonium alum
We describe techniques used to fabricate the cold stage of an adiabatic demagnetization refrigerator that uses the paramagnetic salt ferric ammonium alum. We discuss the design of a leak-tight housing for the salt as well as a technique for growing ferric ammonium alum crystals that results in a housing filled with > 98% refrigerant. These techniques have proven to be reliable in creating robus...
متن کاملHeat switches for ADRs
Heat switches are key elements in the cyclic operation of Adiabatic Demagnetization Refrigerators (ADRs). Several of the types of heat switches that have been used for ADRs are described in this paper. Key elements in selection and design of these switches include not only ON/OFF switching ratio, but also method of actuation, size, weight, and structural soundness. Some of the trade-off are det...
متن کاملThe Continuous Adiabatic Demagnetization Refrigerator (CADR) Innovation Pathway
This pathway describes the development of a Continuous Adiabatic Demagnetization Refrigerator (CADR) within NASA’s Goddard Space Flight Center’s (GSFC, or Goddard) cryogenics and fluids branch. After more than a decade of concerted development efforts, the team is still awaiting a mission opportunity on which to fly the full system. Like the traditional ADR, the CADR will maintain spacecraft in...
متن کاملLarge magnetocaloric effect and adiabatic demagnetization refrigeration with YbPt2Sn
Adiabatic demagnetization is currently gaining strong interest in searching for alternatives to (3)He-based refrigeration techniques for achieving temperatures below 2 K. The main reasons for that are the recent shortage and high price of the rare helium isotope (3)He. Here we report the discovery of a large magnetocaloric effect in the intermetallic compound YbPt2Sn, which allows adiabatic dem...
متن کاملSPICA/SAFARI Sub-Kelvin Cryogenic Chain
SPICA, a Japanese led mission, is part of the JAXA future science program and is planned for launch in 2018. SPICA will perform imaging and spectroscopic observations in the 5 to 210 mm waveband. The SPICA payload features three instruments, one of which, SAFARI, is developed by a European based consortium. SPICA’s distinctive feature is to use an actively cooled telescope down to 4 K. In addit...
