Simulations of the Experimental Spectral Features of Megawatt-Class Gyrotron Fed With an External Signal

We simulate the spectral features of an experimentally implemented gyrotron operating in a 170-GHz band with MW-level output in the frequency-locked regime. Simulations are conducted using the particle-in-cells method within the KARAT software reducing the problem of 3-D simulations of nonsymmetric...

Description
Summary:We simulate the spectral features of an experimentally implemented gyrotron operating in a 170-GHz band with MW-level output in the frequency-locked regime. Simulations are conducted using the particle-in-cells method within the KARAT software reducing the problem of 3-D simulations of nonsymmetric mode operation to the 2.5-D problem. We demonstrate that such an approach allows the spectral features of both frequency-locked and nonlocked gyrotrons to be predicted reliably while using fewer computer resources.
