Helium research in support of superconducting power transmission
Abstract
The preparation of computer codes and numerical computation of SPTL cool down were completed and the results are given. These calculations confirm original intuitive judgement that cool down times for the counterflow arrangement can be long, twenty days or more. Two sections of cable underwent extensive thermal cycling, and the results of these tests are given. The complex structure of the cable leads to unusual (although reproducible) load vs time curves.
