A Polarised Pellet Ignitor: Driver Energy and Gain for Spin-Aligned Fusion Fuel
Year: 2026
Type: article
Abstract: This paper presents a complete design study of a fusion pellet ignitor using spin-polarised deuterium-tritium fuel, computed throughout from stated assumptions. At a polarised fraction of one half, the ignition energy falls to 9.60 kJ, the yield at fixed compression rises to 225.0 kJ, and the gain reaches 23.44, against a gain of 15.00 for unpolarised fuel. At full polarisation the ignition energy is 8.00 kJ and the gain is 33.75. Every figure is a computed result of the stated model and nothing was built or tested: the study is SIMULATED, NOT MEASURED, and its limits are stated as plainly as its performance.
