Expected measurement in Ø 170 mm 4 Experimental setup properties Max. Current1.8 kA Temperature4.2 K – 77 K Sample length240 mm Sample width4-12 mm Max. Field lg19 T Field orientation Up to 14 T under 8° Ø115 Critical current over long length : problem of max. current ? Magnetization measurements under high field / small angles Using hall sensor and pick up coil Behavior of tapes under non-homogeneous field : effect of width ?

Experimental setup in Ø 370 mm : test of racetracks 5 Experimental setup properties Max. Current3 kA Temperature4.2 K racetrack length< 240 mm Max. Field10 T Field orientation Up to 10° Expected measurement Test of cable configurations : twisted stack – face-to-face ? Current distribution Field drift due to magnetization Effect of angle on magnetization
