摘要：

In the work presented here dynamics of spiky microwave emission of a beam-heated plasma near the double plasma frequency in similar to 100 GHz band was studied. The plasma is heated by 80 keV, similar to 2MW, sub-ms electron beam that is injected into the multiple-mirror trap GOL-3. The beam-heated plasma diameter is of the order of the emitted wavelength. Modulation of individual emission spikes in the microwave radiation is found. The radiation dynamics observed can be attributed to a small number of compact emitting zones that are periodically distorted. (C) 2013 AIP Publishing LLC.
