We have studied experimentally the beam-plasma two-stream dissipative collisional instability of relativistic electron beams (REB) injected into plasma produced by interaction of REB with neutral nitrogen. The gas pressure ranged from 0.02 to 8 Torr. REB (T = 100 μs, E = 300 keV, 7 = 3–15 A) were injected into gas through a pulsed foilless valve. An external magnetic field was not used. A description of the experimental setup and that of applied diagnostics are presented. In some of the experiments the inner walls of a metallic interaction chamber were covered with microwave-absorbent material. We present the experimental dependence of the critical current of two-stream instability on gas pressure and beam penetration length. We have also measured the distribution of microwave emission along the beam axis. The influence of plasma self-radiation on the instability was observed and is attributed to a feedback. A possible mechanism of the feedback is discussed.
