Observation of D+D Fusion in Electromagnetically Self-Contained, Long-Lifetime Plasmoids

Authors: Dominik Kuryga, Paulina Nadia Weremczuk

We report the generation of self-contained, long-lived plasmoids in a low pressure coaxial diode of novel concept, driven by a ~5ns up to 1MV pulse, generating neutron bursts consistent with D+D fusion in discharges in deuterium. Neutrons were detected using a silver activation based detector. A correlation was observed between lifetime and neutron yield. Average neutron yields reached approximately 5—7x10u2075 neutrons per shot, with peak values up to 1,4x10u2076 neutrons/shot. Microwave emission measurements were done showing long decaying radiation. The demonstrated detectable nuclear fusion in this novel device opens new perspectives for compact neutron sources and alternative fusion concepts based on self-confined plasmoids.
