For high energy physics appli cations supereon· dueting cables are subjected to large stresses and high magnetic fields during service. It is essential to know how these cables perform in these operating conditions. A loading fixture capable of applying loads of up to 700kN has been developed by NHMFL for LBNL. This fixture permits uniform loading of straight cables over a 122 nun length in a split-pair solenoid in field s up to 12 T at 4.2 K. The first results from this system for Rutherford

However, the cable made from internal· tin s' trand showed a 40 % reduction in " at lIT and 210 MPa while a cable made from modified jelly roll material showed onJy a 15 % reduction in Ie at liT and 185 MP •.
