MODE SELECTION OF A MODERATE POWER GYROTRON OPERATING AT THE ISM FREQUENCY
ISM频率中等功率回旋管的选模问题

Mode selection of a moderate power gyrotron operating at the ISM frequency and the second harmonic is discussed in detail. By analysis and calculation for electron beam wave coupling, mode competition, voltage depression and limiting current, and ohmic losses, considering the compactness of the configuration, the result obtained is that TE 31 mode is probably a best choice for the technology gyrotron operating at the ISM frequency.
