抄録

The space charge wave instability of the spiral beam-plasma system is studied experimentally, under the application of nonuniform magnetic field. The velocity distribution of the spiral electron beam is varied by the mirror effect, which affects the trapping of beam electrons on the potential of the unstable wave. As the results, it is observed that the saturation length and the saturation level of the wave become extremely large, when beam electrons travel with feeling the decreasing magnetic field intensity, and vice versa. The theoretical consideration based on one-dimensional model is given, which explains the experimental results, consistently.
