In this paper, several types of resonant cavities with large transverse cross-section used in gyrotron are briefly reviewed. The method of caleulating the cutoff frequeneies of TE mode of elliptical waveguides with moderate eccentricities is given. From the cal-culated data of cutoff frequencies, it is shown that the gyrotron with elliptical cavity has the following characteristics: (1) a large volume cavity can be used; (2) the dcn-sity of modes which can oscillate is rare; (3) it is allowable to use an electron beam with a large diameter; (4) it is possible to use a cavity mode with low azimuthal number.
