I. Introduction
The ElectroMagnetic Flux Compression (EMFC) is a kind of efficient megagauss field producing device, which is able to generate over 700 T ultra-high magnetic fields in larger volume at present. The EMFC has important applications in solid-state physics (ultrahigh magnetic field physics, high pressure science), and is also likely to find applications in fusion and high-energy density researches [1] [2].
