Abstract :
A focusing magnetic system based on NdFeB permanent magnets creating a field of quasi-solenoidal configuration with a strength of 14.5 kOe in a uniform-field region has been developed. The system has been tested as a unit of a nanosecond, 70 - GHz relativistic BWO with megawatt output power and PRF of 100 Hz. The limitations related to the formation of a shunting radial electron beam in a vacuum diode and to the collimation of the electrons by the anode unit are discussed.
