High-Magnetic-Field Generation by Magnetic Flux Compression in Imploding Plasma Liners

The MIG generator was used in a magnetic flux compression experiment to produce a high magnetic field inside a dielectric tube located along the axis of an imploding plasma liner. With a liner current of ~ 1 MA and a tube diameter of 2-5 mm, magnetic fields of up to 60 T with a quasi-steady pulse duration of 100 ns and more were produced. The high magnetic field region is protected from the liner plasma and radiation by the tube wall, and it can be used to study the physical phenomena that occur in high and ultrahigh magnetic fields. The physical processes responsible for the evolution of the magnetic field in a dielectric tube are discussed.
