The LANL-NHMFL Megagauss Facility has a well-established history of generating ultrahigh magnetic fields beyond 200 T for a broad range of applications. Using the 2-D Loughborough filamentary modeling, a detailed numerical analysis of the single-turn technique was performed. Single-turn calculations for the standard coil (10 × 10 × 3.2 mm) proved to be extremely accurate up to 40-kV capacitor bank charging, corresponding to a field of 185 T, and also revealed important aspects to be observed during experimentation. For pushing the boundaries toward 500 T, a major effort is under way to perform fast electromagnetic flux compression using a pulsed-power system mainly based on the same capacitor bank. Full details of the design for the new arrangement are given, and based on a well-proven 2-D filamentary modeling, the complex phenomena expected during the flux-compression process are highlighted.Index Terms-Magnetic flux compression, numerical modeling, single-turn coil, ultrahigh magnetic fields.
