Modulator cavity of multi-cavitys Gyroklystron transforms the TE411 mode in out cavity to TE011, mode in inner resonant cavity through 4 slots, TE011, mode is used to modulate the transverse velocity of gyroelectron beam. In this paper, an analysis of cold cavity is presented, HFSS code is used to simulate couple of structure variety accurately and revise approximate analysis. It shows ratio of inner cavity's energy storage to that of outer cavity's is 41.65, When angle between coupling slots' midline & waveguide axis is 45°. Length of slots affects Q factor greatly while resonance frequency is insensitive to it, moreover, Q factor relate with length of slots more sensitive than width of them. Energy storage in coaxial cavity has been calculated. Based on a large number of calculations and simulations, the optimal modulator cavity meeting the design requirement is attained.
