Abstract

The radial profile of the neutron production rate in spherical inertial electrostatic confinement fusion devices (IECF) is investigated. The electrostatic potential is determined by solving the Poisson equation, and by using the potential; the fuel ion energy distribution function is determined at each radial point. From the energy distribution function, the fusion reaction rate is evaluated. Dependence of beam-beam and beam-background reaction rate on some important parameters as the spreads in the normalized angular ion energies, working pressure, and grid transparency are investigated.
