Jc(T,B) and E(T) Dependencies for NbTi Strands Used in ITER PF Insert Coil

In the framework of the characterization of NbTi strands manufactured by Bochvar Institute for the ITER insert coil the representative database of J c (B,T) and E(T) was obtained. Measurements of J c (B,T) were carried out on the samples taken from several batches of the strand at magnetic fields ranging from 5 to 9 T and temperature range from 4.2 to 7 K. All the strands were produced using the identical heat treatment route. The E(T) characteristics were recorded to simulate the current sharing temperature (T cs ) test for ITER PF coil. The T cs compiles 6.1 K-6.3 K at magnetic field of 6 T.
