Abstract

A numerical model is constructed for calculating the evolution of the ion distribution function in an axially symmetric open trap. A single force tube with uniform distribution of parameters over the cross section is considered. The phase space is parameterized by the total energy and magnetic moment. The Rosenbluth–Trubnikov potentials are calculated from the distribution functions averaged over angles. A Maxwellian distribution of electrons with the same temperature is assumed throughout the computational domain.
