ON THE CRYOGENIC ASPECTS OF PROJECT SHERWOOD. Fifth Progress Report, January 1, 1961 to March 31, 1961

Technical Report ·
OSTI ID:4840119
The superconductivity of a Nb/sub 2/Sn wire was studied in pulsed magnetic fields of 185 kilogauss, and the critical field was found to be approximately 188 kilogauss at 1.6 deg K. Electrical resistivity measurements are reported for high-purity Al. The status of refrigeration cycle analysis is described. The turbo-expander, for use in a He refrigeration system, was tested and its gas-lubricated bearings found stable at operation up to 7 kw refrigeration. (D.L.C.)
