Summary: | First simulation results on interaction of a long and thin magnetized plasma column with a 100 keV electron beam are presented. Selected parameters are similar to those in the real GOL-3 experiments. To simulate the realistic problem of continuous beam injection into a plasma, we use a 2D3V particle-in cell code allowing for the open boundary conditions in the beam direction. It is shown that such a thin system appears to be unstable against the quasi-regular longitudinal density modulations and generates the fundamental and second harmonic emissions via the antenna mechanism. The radiation power of such an antenna is found to reach 0.6% of the total beam power. |
