Objective
The goals of the project are theoretical and experimental investigations of magnetic energy accumulation, current sheet formation, magnetic reconnection phenomena and particle acceleration as they occur in high-conductive plasmas in three- and two-dimensional magnetic fields of different topology.
Field-reversed theta-pinch configurations, two-dimensional fields with zero-lines and X-type lines are of the highest interest. Major problems under study are the magnetic energy accumulation by the current sheet formation, the energy release through the reconnection phenomena, the ways of energy transformation, the correlation between thermal processes and the impulsive stage of magnetic reconnection, and the emission properties of plasmas compressed into current sheets.
In the framework of the project the following work will be done: experimental investigations of the magnetic reconnection in high-density discharges in theta-pinch geometry; installation of magnetic probes to study the magnetic topology; investigation of spectral line profiles; experimental investigations of magnetic energy accumulation, current sheet information, magnetic reconnection phenomena in 2D and 3D magnetic fields of different topology; development of experimental techniques for the analysis of electric current distribution and spectral line shapes; theoretical study of the magnetic energy accumulation in the course of the MHD-wave propagation in the magnetic fields with the X-type points; theoretical study of particle acceleration near X-type points; computer simulation of the MHD-wave propagation and the current sheet formation at the magnetic fields with X-point; computer simulation of the current sheet formation and magnetic reconnection phenomena at 2D and 3D magnetic configurations; theoretical investigations of non-linear dynamics of perturbations bringing energy to an x-point and its separatives, study of fast reconnection, relevance of finite electron mass effects; theoretical investigations of the acceleration of test particles due to the electric fields generated by reconnection processes; theoretical simulation of current sheets and reconnection in 2D and 3D configurations; analytical and numerical studies of fast reconnection and the accumulation of wave energy in X-points; numerical calculations of equilibrium sequences to investigate the non-linear evolution.
