摘要：

The critical current degradation of a few Rutherford type of Nb3Sn cables are investigated as function of transverse pressure. Moreover a comparison is made between Nb3Sn strands produced according to the Powder-in-Tube, the Bronze and the Modified Jelly Roll process. The (keystoned) Rutherford cables are charged at 11 T with transverse pressures up to 250 MPa. Large differences in critical current reduction are observed, ranging from 6 to about 60% at 200 MPa depending on the type of Nb3Sn. It appears that the irreversible part is about 40% of the total reduction. Moreover, the "irreversible" part shows relaxation and a partial recovery is possible by thermal cycling.
