  • Abstract
    An extremely high power, second harmonic TE21 gyrotron traveling wave amplifier (gyro-TWT) utilizing a MIG beam will be described. Based on a marginal stability procedure [1], a second harmonic gyro-TWT using a 100 kV, 25 A MIG beam with α = 1 and Δvz/vz = 5% has been designed, where the total interaction tube is comprised of three sections separated by absorbing severs. The length of each section is shorter than the length at which the device will spontaneously oscillate, which is determined through a combination of analytical theory and multimode PIC code simulation. The number of sections is chosen to yield the desired gain. An output power of 500 kW, efficiency of 21% and bandwidth of 7% have been obtained through self-consistent nonlinear simulations for the designed amplifier.
