Numerical Model of Nonstationary Plasma in Axially Symmetrical Open Trap MIDAS-1D2V

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.

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
