Abstract :
The Nb3Sn magnet toroidal field coil assembly of Tokamak T-15 has shown its workability up to the rated magnetic field (3.5 T at the axis and 6.6 T at the coils). The dependence of the quench current on winding temperature was obtained. Its extrapolation shows that operation at 4.5 T will be possible at a temperature of 4.5 K. The coil which limits the total current of the coil assembly was identified. Poloidal field changes produced by plasma current disruptions with a field change rate of up to 15 T/s did not disturb the coil assembly operation
