Abstract
We report a novel compact nuclear fusion concept based on a 20 MeV tabletop electron storage ring (ESR), which electrostatically confines and accelerates deuterium and tritium ions to fusion-relevant energies. The ESR generates a relativistic potential well exceeding 700 kV, capable of trapping high-density ion populations. Additional DC acceleration enables ion heating above 50 keV to initiate D-T fusion. Analytical calculations and simulations suggest that a confined ion population of 10^17 within a volume of 1.25 × 10^-5 m^3 can yield fusion power exceeding 2 MW. This ESR-based approach offers a potential pathway toward compact, efficient, and modular fusion power systems.
