Abstract :
The paper is devoted to the experimental results obtained in 1992-1993 on the T-15 superconducting toroidal field coil with a stored energy of 380 MJ using Nb3Sn. The critical current dependence on the temperature in the range Tin=4.5-12 K was obtained. The current 4.0 kA was achieved, which corresponds to a magnetic field at the axis of 3.6 T and a peak field at the conductor of 6.5 T. The level of the resistive heat load versus transport current was studied-Q res achieves 300 W at 3.6 kA. It was shown that plasma current disruptions with a rate up to 80 MA/s did not affect the coil stability
