The RRR Parameter of the ITER Type Bronze-Route Cr-Coated Nb 3 Sn Strands After Different Heat Treatments

Residual Resistance Ratio (RRR) is one of the relevant parameters for hbox Nb 3 hbox Sn strands and cables to be used in windings of high field magnet systems. The increase of the cable stability is provided by attaining of the high RRR-values. However, the RRR values of strands comprising the cable...

Description
Summary:Residual Resistance Ratio (RRR) is one of the relevant parameters for hbox Nb 3 hbox Sn strands and cables to be used in windings of high field magnet systems. The increase of the cable stability is provided by attaining of the high RRR-values. However, the RRR values of strands comprising the cable could deviate significantly from the average ones.
