Abstract :
Ion-focusing of electron beams in high-power linear-beam microwave tubes is considered, and a qualitative discussion of the defocusing mechanism of an externally applied RF power is presented. The primary mechanism of beam breakup is the space-charge force of bunched electrons which limits the use of ion-focusing in high-power tubes.
