| 摘要 |
Microwave pulses at power levels in excess of 10 megawatts and of short duration and narrow bandwidth are produced by propagating an annular relativistic electron beam carrying currents of 30-40 kA at energies of 200-500 keV through a cylindrical, symmetrical annular, ridged wave guide. The interaction between this beam and a backward wave in the guide leads to the oscillations.
