Adiabatic, chaotic and quasi-adiabatic charged particle motion in two-dimensional magnetic field reversals.
Abstract
For a number of problems in plasma astrophysics it is necessary to know the laws, which govern the non-adiabatic charged particle dynamics in strongly curved magnetic field reversals. These are, e.g., the kinetic theory of the microscopic and macroscopic stability of current sheets in a collisionless plasma, of microturbulence, causing anomalous resistivity and dissipating currents, the problem of spontaneous reconnection, the formation of non-Maxwellian distribution functions, particle acceleration and the use of particles as a diagnostic tool ("tracers"). To find such laws the authors derived from the differential equations of motion discrete mappings. These mappings allow an investigation of the motion after the break down of the adiabaticity of the magnetic moment.
