Experimental Study of a 6 kW W-band PCM Focused Sheet Beam EIO

The study and experimental studies of a 6 kW W-band PCM focused high power sheet beam extended interaction oscillator are firstly reported. The initial hot test results show a 6 kW maximum output peak power with a 47.2 kV and 2.1 A beam. An average power of 1.2 kW is obtained with a 20% working duty. The stable operation shows a much higher potential average power capability. A new designed PCM magnet is applied in the beam focusing. It presents a 99% static beam transmission and 94.4% beam transmission with saturated RF interaction. The overall dimensions and weight of the SBEIO are 400×100×60 mm and 7 kg.
