INVESTIGATION ON THE POSSIBILITY TO MAKE USE OF SLOWLY VARYIMG ELLIPTICAL TRANSITION REGION IN CAVITY OF GYROTRON TO SUPPRESS HIGH ORDER UNWANTED MODES
It is proposed to introduce a specially designed cavity: in the interaction region, the circular cross-section is kept, beyond which a slowly varying elliptical auxiliary transition section is used to suppress the unwanted modes. The cavity is so designed: the fields of unwanted modes can penetrate to the auxiliary section, but that of the operating mode can not. If we then load the auxiliary section, the unwanted modes can be attanuated but the operating mode (cTE0n and sTE1n) maintained.
