Summary

Friction experiments are reported for relative motion between niobium-titanium/copper windings coated with formvar, ie, for a superconductor with low-transition temperature. A heat flow meter technique is used based on zero net mass flow heat piping in helium II. The friction factors obtained are consistent with results deduced from other techniques. From the data obtained, adiabatic, limiting displacements (at quench) are calculated for high-transition temperature composite conductors. The comparison with low-transition temperature results shows that they will not be a critical parameter for the present winding friction model at high-transition temperature.
