Abstract :
The suppression of TE mode oscillations in a PPM-focused S-band sheet beam klystron amplifier using a method of loading distributed losses is presented. This method allows us to make a reasonable attenuation of unwanted modes relative to the operating TM mode and can be used to improve the stability of beam-wave interaction circuit with high aspect ratio.
