The systems and methods described herein relate to the use of electrostatic elements to confine and circulate ions in trapped orbits so as to facilitate ion-ion and ion-neutral collisions resulting in nuclear fusion reactions. The systems employ a disc shaped cloud of ions wherein the turning region for the recirculating ions are located in a circular space around the periphery of the disc-shaped ion cloud, thereby maximizing the turning space region to increase the number of ions trapped in the device compared to discrete beam devices, which in turn enables higher fusion yield compared to prior art devices.
