A Compact Explosive-Driven Flux Compression Generator for Reproducibly Generating Multimegagauss Fields

Explosive-driven magnetic flux generator is one of the most efficient techniques for producing ultrahigh magnetic fields in a relatively large volume. To create a more reliable system suitable for extreme magnetic fields applications, a compact explosive-driven magnetic flux compression system with a small amount of explosive for generating multimegagauss fields was developed. In this paper, the design for reproducibly generating megagauss fields, and the experimental results of this generator are presented in detail. The experimental results show that peak fields in the range of 580-710 T can be reliably generated by the generator with about 3-kg Comp-B explosive.
