Abstract

Experiments at the GOL-PET facility have shown that injection of a relativistic electron beam at kiloampere current into a magnetized plasma column with strong radial density gradients is accompanied by generation of THz radiation flux which power estimated at the level of several megawatts. Extraction of this flux along the axis of the beam-plasma system is essentially increased in case when the end of the plasma column is separated by a vacuum gap from the wall of a plasma chamber. Results of measuring the spatial and angular properties of such megawatt flux of THz radiation going out from the plasma to an air of the experimental hall are described in our paper.
