Wave Driven Rotation in Supersonically R

Supersonic rotation in mirrors may be produced by radio-frequency waves that cause coupled diffusion in ion kinetic and potential energy, leading to a population inversion along the diffusion path which produces rotation. This study investigates the feasibility of using radio-frequency waves to create rotation in magnetic mirror traps without relying on traditional electrode methods. The waves may exploit a natural kinetic energy source or generate the necessary rotation energy independently. The findings suggest that implementing this mechanism could enhance axial confinement and magnetohydrodynamic stability in fusion applications, as well as improve plasma centrifuges for isotope separation, offering higher separation efficiencies than gas centrifuges due to larger rotation speeds. Significant design challenges have included overcoming limitations of electrode-based systems, particularly the Alfven critical ionization velocity, which has hindered the effectiveness of rotation in various applications. This paper highlights the potential of using volumetric wave-driven rotation to address these limitations and improve the efficacy and application of magnetic mirror traps in advanced nuclear fusion and isotope separation technologies.
