Gigawatt power generation on KALI system using relativistic backward wave oscillator

Relativistic backward wave oscillators (RBWO) are widely used high power microwave (HPM) devices due to their ease of operation and simple geometry. This paper presents the RBWO power generation experiments carried out on KALI 30 GW pulse power system. We have used 600 kV, 7 kA electron beam to generate 0.8 GW HPM power with 3.28 GHz frequency. A magnetic field coil is designed for retaining this electron beam into its path. The output mode was TM
₀₁
mode. It was confirmed by putting a neon lamp array in the far field radiation area of the RBWO antenna.
