DESIGN OF AN ADIABATIC DEMAGNETIZATION CRYOSTAT FOR ULTRASONIC ATTENUATION STUDIES.

Abstract

A cryostat for low temperature research was designed with minimal changes to an existing He3 refrigerator. The new design provides for isothermal magnetization and subsequent adiabatic demagnetization of a paramagnetic salt to reach temperatures as low as 0.06 K. The cryostat is to be used for ultrasonic attenuation studies of superconducting metals with low transition temperatures. The low temperature is necessary to obtain accurate comparison with the BCS theory, which predicts a constant zero degree superconducting energy gap for all superconductors of 3.50 kT. (Author)
