高达300 T（3 MG）的超高磁场已经通过电磁通量压缩产生，仅使用来自快速电容器组的63 kJ来内爆铝衬垫，来自慢速电容器组的14.7 kJ需要提供初始磁场。在没有初始磁场的情况下，产生并测量了时间变化率超过3 × 108 T s-1的磁通密度脉冲，为一系列动态Transformer应用开辟了道路。这项工作的结果表明，当使用快速多MA银行，磁通量压缩可以被视为替代单匝线圈技术，将移动磁场的边界远远超过300 T，而不需要显着的额外投资。
Ultrahigh magnetic fields up to 300 T (3 MG) have been generated by electromagnetic flux compression using only 63 kJ from a fast capacitor bank to implode aluminium liners, with 14.7 kJ from a slow capacitor bank needed to provide an initial magnetic field. With no initial field present, pulses of magnetic flux density having a time rate-of-change exceeding 3 × 108 T s−1 have been produced and measured, opening the way for a range of dynamic transformer applications. The outcome of the work suggests that, when using fast multi-MA banks, flux compression can be viewed as an alternative to the single-turn coil technique that will move the boundary of the magnetic fields well beyond 300 T without the need for significant additional investments.
