A compact pulsed power driver with precisely shaped current waveforms for magnetically driven loading experiments.

Magnetically driven loading techniques based on high current pulsed power drivers are very important tools for researching material dynamic behaviors and high-pressure physics. Based on the technologies of a Marx generator energy storage and low impedance coaxial cable energy transmission, a compact high current pulsed power driver CQ-7 was developed and established at the Institute of Fluid Physics, China Academy of Engineering Physics, which can generate precisely shaped current waveforms for magnetically driven loading experiments. CQ-7 is composed of 256 two-stage Marx generators in parallel with low impedance, high voltage coaxial cables for current output.

A 200 kJ electrical gun for hypervelocity launch.

In order to meet the requirements of hypervelocity launch in the context of defending against space debris and deflecting asteroids, an electrical gun with 200 kJ of storage energy was recently built. The electrical gun is composed of 16 gas spark switch-capacitor modules, and pulse current is transmitted by parallel aluminum plates that are insulated by polyester foils. The capacitance, inductance, and resistance of the RLC circuit of the 200 kJ electrical gun are 80 µF, 10.
