A device for generation and accumulation of plasma with relativistic electron temperature by means of the gyromagnetic autoresonance

Results of an experimental study of a relativistic plasma generated by means of the gyromagnetic autoresonance in the plasma synchrotron accumulator called GYRAC-D are presented. The use of a new heating scheme in the regime of a train of pulses with the further accumulation of the generated plasma in a mirror magnetic configuration and improvement of vacuum conditions owing to a system of external injection make it possible to obtain a plasma with the following parameters: Te≊200 keV, ne≊1× 109 cm-3, and lifetime approximately 1 s. No major obstacles to further increase the density are observed.
