PROTOTYPE TESTS AND DESCRIPTION OF A 60-TESLA QUASI-CONTINUOUS MAGNET

The National High Magnetic Field Laboratory has designed and will buil d a large bore, 60 tesla, 100 ms (quasi continuous) flat-top magnet fo r installation and use at Los Alamos. The magnet consists of eight con centric, resistive, solenoid coils fabricated from high strength, high conductivity copper supported by external stainless steel shells. Bef ore each pulse the magnet is cooled to 77 K with liquid nitrogen. The energy for the magnet is provided through converter power supplies fro m a 1430 MVA, 24 kV alternating current energy storage generator. Plan s for prototype tests of full scale portions of the magnet are discuss ed. A detailed description of the magnet is presented along with avail able information on fabrication methods to be employed in its manufact ure.
