A Torsion-Seeded Plasma Heater: Heating Rate for a Fusion Fuel Stream from Spin Relaxation

This paper presents a complete design study of a plasma heater that deposits energy into the spin degree of freedom of a polarised fuel stream, computed throughout from stated assumptions. At a density of 1.0e+20 per cubic metre the deposited power density is 0.120 MW per cubic metre and the stream heats at 2.50 keV per second, needing a residence time of 0.8011 s to climb the stated interval. The heating rate is 2.50 keV per second at the lowest density scanned as well, since it is density-independent in this model, and the residence time is 0.8011 s at every density, because deposited power and thermal capacity scale together; the power density reaches 1.200 MW per cubic metre at the highest density. 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.
