Magnet. Part VI—Power Supply

The power for the Cosmotron magnet is supplied by a 1750‐hp 13 800‐volt induction motor that drives a 21 000‐kva 12‐phase ac generator and a 43‐ton flywheel, rotating at approximately 900 rpm. The generator output is rectified through 24 double‐grid ignitrons which also act as inverters returning most of the magnetic energy of the coil to the rotating set.
