First 100 T non-destructive magnet outer coil set

The controlled power outer coil set of the first 100 T non-destructive (100 T ND) magnet Is described. This magnet will be installed as part of the us er facility research equipment at the National High Magnetic Field laborato ry (NHMFL) Pulsed Field Facility at Los Alamos National Laboratory. The 100 T ND controlled power outer coil set consists of seven nested, mechanicall y independent externally reinforced coils. These coils, in combination, wil l produce a 47 T platform field in a 225mm diameter bore. Using inertial en ergy storage a synchronous motor/generator provides sc power to a set of se ven sc-de converters rated at 64 MW/80 MVA each. These converters energize three independent coil circuits to create 170 MJ of field energy in the out er coil set at the platform field of 47 T. Each coil consists of a multi-la yer winding of high strength conductor supported by an external high streng th stainless steel shell. Coils with the highest magnetic loads will utiliz e a reinforcing shell fabricated from highly cold worked 301 stainless stee l strip. The autofrettage conditioning method will be used to pre-stress th e coils and thereby limit conductor and reinforcement strains to the elasti c range. The purpose of pre-stressing the coils is to attain a design life of 10,000 full field pulses. The operation and conditioning of the coil set will be described along with special features of its design, magnetic and structural analyses and construction.
