Fokker–Planck Simulation of Fast-Ion Kinetics in Z-Pinch Implosion Taking into Account Electromagnetic Acceleration

Kinetic approach to simulation of ion velocity (and energy) distribution function in the process of Z-pinch neck implosion, along with the energy spectrum of ions leaving the neck, are analyzed. A combination of acceleration in a magnetic field growing with time, Coulomb collisions, and losses determine the formation of ion spectrum within the framework of the kinetic Fokker–Planck equation.
