Abstract

The National High Magnetic Field Laboratory has designed and will build a large bore, 60 tesla, 100 ms (quasi continuous) flat-top magnet for installation and use at Los Alamos. The magnet consists of eight concentric, resistive, solenoid coils fabricated from high strength, high conductivity copper supported by external stainless steel shells. Before each pulse the magnet is cooled to 77 K with liquid nitrogen. The energy for the magnet is provided through converter power supplies from a 1430 MVA, 24 kV alternating current energy storage generator. Plans for prototype tests of full scale portions of the magnet are discussed. A detailed description of the magnet is presented along with available information on fabrication methods to be employed in its manufacture
