Abstract

Helium-boil-off calorimetry was used to measure AC loss in uncored Nb 3Sn Rutherford cables in the perpendicular and parallel orientations of the applied field. The five cables selected for study had widths of 8, 13, and 16 mm and strand counts of 20, 30, and 36, respectively. Under various surface conditions describable as "as-cabled", "solvent- rinsed", or " HCl-rinsed", they were reaction heat treated (RHT) then vacuum impregnated with resin in preparation for measurement. Calorimetric measurements of AC loss, and hence interstrand contact resistances (ICR) were made at 4.2 K in background fields of 0 T and 1 T, and sinusoidal fields of amplitude 400 mT and frequencies of 5 to about 90 mHz. The ICRs of the various uncored cables are compared. A comparison is also made to the ICR of a previously measured cored Nb 3Sn cable.
