We present the results of investigations of microwave radiation from a strong-current relativistic beam of microsecond duration, 3 kA current, 230 keV energy, and 1.2χ 10-6 sec duration. It is shown that microwave radiation of several megawatt power is observed when an annular beam of these parameters is injected into a spatially-periodic magnetic field.
