Temperature Control

Abstract

Over the entire range of temperatures which are accessible to Mössbauer studies, it is possible to regulate temperature to better than 1 part in 104. The use of thermocouples for electronic measurement and control is useful above 10°K. In the region from 0.03 to 20°K, germanium and carbon resistance thermometry is convenient and reliable. Over limited temperature ranges, very precise regulation is available through control of the vapor pressure above a cryogen. The resistance-bridge and temperature-control unit for the 0.03°K dilution refrigerator in operation at Los Alamos is discussed. Co57 Mössbauer thermometry below 1.0°K is also discussed.
