Design and computer simulation of a gyrotwystron

We have designed a 4.5 GHz gyrotwystron consisting of an input cavity, a stagger tuned intermediate cavity and an output waveguide operating in the TE° 11 , mode. Using a non-linear simulation code, we predict operation with a saturated gain of 22 dB, an efficiency of 22.5%, an output power of 60 kW...

Description
Summary:We have designed a 4.5 GHz gyrotwystron consisting of an input cavity, a stagger tuned intermediate cavity and an output waveguide operating in the TE° 11 , mode. Using a non-linear simulation code, we predict operation with a saturated gain of 22 dB, an efficiency of 22.5%, an output power of 60 kW and a bandwidth of ∼2%. The efficiency and gain are similar to those achieved in a three-cavity gyroklystron operating at the same frequency, but the bandwidth is about an order of magnitude larger. Changing the profile of the B field optimizes efficiency and gain but decreases the bandwidth.
