| 摘 要： | In this paper,the method of calculating cut-off frequencies of TE modes in elliptical waveguideis given.From the calculations,it is demonstrated that the gyrotron utilizing a cavity with ellipticalcross-section of moderate eccentricity has the following characteristics:(a)a large volume cavitycan be used;(b)the density of modes which can oscillate is low;(c)it is allowable to use an electronbeam with a large diameter;(d)it is possible to use a cavity mode with low azimuthal number. |
