A Novel Technique for Pulsing a High Magnetic Field

Radar modulator techniques, which make use of pulse-forming networks (PFN), were used to develop a magnet pulser which supplies 500-amp current pulses to a 20-turn tape-wound coil for generating a pulsed, high magnetic field. Uniform fields of more than 5 kilogauss were generated with pulse widths of 6 to 14 ¿sec at repetition rates up to 1200 Hz. New cooling techniques for the load coil and the pulser components are being developed so that higher fields at higher repetition rates can be generated.
