Pacific Fusion’s High Gain Fusion Pulser

We describe Pacific Fusion’s Demonstration System (DS), a high-gain [1] and high-yield fusion capability. DS drives deuterium-tritium filled cylindrical targets to ignition and high target gain (GT~10), with the goal of demonstrating facility gain GF >= 1. The pulser is equipped with an extensive diagnostic suite, building upon decades of research in inertial confinement fusion. We discuss considerations for Hertz-class repetitive pulsed applications, and the unique pulse shaping capabilities that distinguish Pacific Fusion’s Demonstration System as a versatile high-gain fusion system. We will present the overall system architecture, the pulser design that delivers the required 60+ megampere, 100 nanosecond pulses to a high gain target, and the operations and safety considerations for the facility.
