Abstract
We report the first gyrotron-backward-wave-oscillator experiments whic h utilize a high-current (1-4 kA) high-voltage (300-500 keV) annular e lectron beam. The experiment was designed to operate in the TE(01) bac kward wave mode, Radio frequency extracted power was 0.1-4 MW, with pu lselengths of 80-500 ns. Experimental results suggest the possibility of competition with the TE(21) backward wave mode. Frequency spectrum measurements have shown a wide content of frequencies during the volta ge pulse, an undesirable result for use in narrow-hand devices.
