The Transport of Heavy Charged Particles in a Cylindrical Nuclear-Pumped Plasma

The transport of heavy particles produced by the ¹⁰B(n,α)Li and ²³⁵U(n,νn)ff nuclear reactions in a two-region cylindrical geometry is analyzed. Total spatially dependent energy current, power density, and transport efficiency are calculated. These results are significantly different from what would be predicted using a two-region slab model—the model generally used for kinetic analysis of nuclear-pumped plasmas. The calculated transport efficiency for a 0.4 mg/cm^{2 10}B coating was 9% and 16% for a 3.3 mg/cm^{2 235}UO₂ coating.
