Advances in ElectroMagnetic flux-compression research

The ElectroMagnetic Flux Compression (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. In the Institute of Fluid Physics (IFP), Chinese Academy of Engineering Physics (CAEP), a mediumsized EMFC device has being developed to carry out some extreme physics researches. The device includes a 1 MJ main capacitor bank and a 200 kJ initial field capacitor bank. A 2D numerical model is developed to estimate the performance of the device. In the model, the filamentary method was employed to solve the electromagnetic problem of the EMFC process, while the mechanical part was calculated by the commercial software. The numerical simulation estimated that the peak current of main bank is over 3 MA, and the peak field is about 350 T Φ11mm) and 550 T Φ6mm) respectively.

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].
