Pulsed Power Systems and Impedance-Matched Marx Generators (IMGs) thefusionreport.substack.com

Michael Heumann’s article explains how pulsed-power systems store energy and release it in brief bursts to drive fusion, then focuses on impedance-matched Marx generators (IMGs) for inertial fusion. It describes Pacific Fusion’s planned demonstration system, which aims to combine IMG modules to deliver over 60 MA and more than 8 MJ to a MagLIF target in a roughly 100-nanosecond pulse, while noting that commercial use depends on improving efficiency, reliability, component lifetime and firing rates.
