Model WE-CBHS-1MJ
1 MJ Pulsed Capacitor Bank Module
Proven Pulsed Power Architecture for Plasma Fusion Research
Our 1 MJ Pulsed Capacitor Bank delivers megajoule-scale energy storage and high-current discharge capability refined through decades of fusion plasma research. Storing 1 megajoule across 22 paralleled 826 μF / 11 kV capacitors arranged in a low-inductance parallel architecture, the bank generates 220 kA peak discharge currents through a Type D Ignitron —sufficient to drive plasma guns, Ohmic heating coils, and high-current fusion diagnostics requiring microsecond-scale energy delivery. Per-module 24V charge relays enable selective energy staging from single-module commissioning tests through full-bank plasma experiments, critical for phased research programs where experimental protocols evolve from proof-of-concept demonstrations to high performance fusion shots.
