Dependence of Neutron/Proton Production Rate on Discharged Current in Spherical Inertial Electrostatic Confinement Plasmas

Abstract

The correlation between proton production rate and discharged current in D-3He spherical inertial electrostatic confinement (SIEC) plasmas is studied for various ion/electron distribution functions. In high energy (more than ~50 keV) range, the 3He(d,p)4He fusion cross section increases more rapidly than the D(d,n)3He one with increasing relative energy between beam-ion and background gas. It is shown that if electrons have high convergence and energetic component compared with ions, the proton production rate in deuterium-helium-3 gas systems can increase in proportion to more than a power of the discharged current more easily for higher discharged voltage than that in the deuterium-gas systems.
