FAST SMES FOR GENERATION OF HIGH-POWER PULSES

A technique for generation of high power pulses based on a fast SMES h as been developed and a model of a power modulator for linear accelera tors was built. The basic function of the modulator that generates 2 m s long, approximately 1 MW power pulses at a repetition rate of 10 Hz is described in this paper, A modular construction of the SMES that co nsists of up to six coils has been chosen to meet the demands of sever al applications in high energy physics and energy distribution, The ra te of change of magnetic field achieved during ramping of the magnet w as more than 60 T/s without a quench, The magnet was designed with res pect to the high AC losses during repetitive ramping of the SMES. The suitability of mined matrix superconductors instead of more expensive net frequency wires for this kind of AC stress was investigated, The a pplied mixed matrix Cu/CuNi/NbTi wire and the construction of a single coil is described.
