SOLUTION TO THE FOKKER-PLANCK EQUATION FOR HIGH ENERGY IONS
A steady state solution to the Fokker-Planck equation for the distribution in pitch angle and velocity of fast ions slowing down into a multispecies Maxwellian plasma is given. The analysis extends previous results to the velocity regime 1.8 v-i <v<0.8 v-e, where v-i and v-e are the ion and electron thermal velocities, respectively. Consequently the solution models classical slowing down of fusion reaction products, such as alpha- particles. The solution also covers, and corrects, earlier results for the distribution function of slowing down neutral beam ions.
