E-beam transportation features in GOL-3 facility

Results on transportation of the high-current relativistic electron beam (1 MeV, 40 kA, 8 μS) through the 17-m-long channel with magnetic field on GOL-3 facility are presented. The beam is formed in the ribbon diode of the U-2 generator and then it is injected into the l2-meter plasma column of the multimirror trap GOL-3. Dynamics of the beam and plasma currents, which results in formation of radial structure of helical magnetic field, is described. Radial profile of rotational transformation was directly measured. This data allow us to identify mechanism of stabilization of the beam - plasma system.
