Nuclear Engineer

Fuse is on a mission to accelerate the world’s transition to fusion energy. Our core product is TITAN: an Impedance Matched Marx Generator (IMG). TITAN is the most efficient and powerful (TW) machine of its kind. Fusers have built and licensed Magical Unicorn and FAETON I, 2 novel pulsed power generators.
