Abstract
The key point of gyrotron design is the analysis of the radio frequency (RF) behavior in gyrotron resonators. This article proposes a comprehensive, user-friendly and effective gyrotron design toolbox (GYROCOMPU) based on the MATLAB platform. GYROCOMPU associates a relatively complete set of codes for gyrotron analysis and integrates them together into a graphical user interface (GUI). The solving algorithm of the cold cavity equations and self-consistent equations is improved. The solving method improvement in these calculation algorithms renders the analysis more efficient and accurate. Three typical examples of gyrotrons working in the 140-GHz TE03 mode, 42-GHz TE03 mode, and 140-GHz TE10,4+ mode are analyzed. All main codes, including the cold cavity calculation, starting current calculation, self-consistent calculation, and mode competition calculation, are compared with the classical code package (COAXIAL) or with results from the literature. The simulation results show that GYROCOMPU can accurately and effectively complete the analysis of gyrotrons.
