Abstract
The electric field in a plasma-filled X-band backward wave oscillator (BWO) was measured by the Stark-effect method. Field strengths were as high as 110 kV/cm when the BWO power level was approximately 75 MW. O bserved electric fields lasted throughout the approximately 60 ns high power microwave pulse. After this pulse, fields 30 to 40 kV/cm persis ted until beam shutoff, presumably arising from beam-plasma turbulence and low power level electromagnetic radiation.
