| Abstract: | The paper presents a three-mirror quasi-optical cavity(TMQOC) high power radiation source,which includes a column slow-wave grating and two spherical mirror reflectors.A TMQOC system has been designed on the basis of simulation and theory calculation.With a ring beam passing over the column grating surface,the TMQOC radiation source can output a power of 1.2 MW at W-band,under the condition of guiding magnetic field of 2.2 T,diode voltage of 557 kV,beam current of 1.8 kA with duration of 70 ns. |
