EFFECT OF NUCLEAR ELASTIC-SCATTERING ON FUSION REACTIVITY OF SELF-SUSTAINING D-HE-3 PLASMAS

On the basis of coupled kinetic/power-balance calculations, we examine the degree of recoil tail creation due to nuclear elastic scattering and its effect on the fusion reactivity of self-sustaining D-He-3 plas mas. It is shown that at a typical operating state (e.g. T-i(bulk) = 1 00keV), the d-d [d-t] reaction rate parameter increases by 10-20% [dec reases by less than or equal to 10%] from the values for Maxwellian di stributions, while the d-He-3 reaction remains almost unchanged.
