Summary

THE MEASUREMENTS SHOW THAT A HEAT FLOW RATE OF 0.6 W CM-2 AT 4.2 K IN THE NB3SN COMPOSITE CONDUCTOR GUARANTEES A STABLE OPERATION EVEN AT LOCAL HEAT INPUTS OF ABOUT 0.5 J ONTO THE SURFACE OF THE CONDUCTOR. IN SUPERFLUID HELIUM, RECOVERY UP TO THE TAKE-OFF VALUES OF CURRENT IN MAGNETIC FIELDS BETWEEN 8 T AND 13 T WAS FOUND. A THEORETICAL ANALYSIS WAS PERFORMED TO EXPLAIN THE EXPERIMENTAL RESULTS WITH RESPECT TO THE COOLING CHANNEL GEOMETRY, MAGNETIC FIELDS, AND THE LOCAL ENERGY INPUTS TO INITIATE A NORMAL CONDUCTING REGION.
