Author(s): T. J. Awe, B. S. Bauer, S. Fuelling, and R. E. Siemon
The first measurement of the threshold for thermal ionization of the surface of thick metal by pulsed magnetic field (B) is reported. Thick aluminum—with depth greater than the magnetic skin layer—was pulsed with ∂B/∂t from 30–80  MG/μs. Novel loads avoided nonthermal plasma (from ele…
