Abstract
The processes in the magnetized plasma are influenced by
spontaneous generated internal magnetic fields and induced currents. In the
plasma with high density of particles convenient for ICF we can observe very
fast energy transformation in range of ps or ns. In that plasma the high
energy electrons and ions occur. Problem of their acceleration is under
discussion. One possible mechanism is based on the transformation and
dissipation of internal magnetic field. In this case the reconnection of
magnetic lines can play an important role. This problem is studied for
example in solar flares as well. In this paper we present results of the
development of the discharge with distance of electrodes 40 cm, current of
300 A and duration in order of 100 ms. Its behavior is directed by
magnetohydrodynamic phenomenon - pinching, development of helical
instabilities, connection of two channels with opposite orientation of the
electric current, forming of the loops, squirm of the loops and forming and
disintegration of spherical forms of the squirmed loops.
