title: Generation of quasistatic magnetic fields.
abstract: A prototype switching system has been developed which can switch 20 kA at 230 V furnished by low-voltage dc generators at the National Magnet Laboratory. The energy is used to generate quasistatic magnetic fields in liquid-nitrogen-cooled copper coils for times approaching 1 s. The present arrangement is limited to fields up to 40 T. The silicon-controlled rectifier switching system, protective devices, circuit operation, and magnet structures are discussed.
