Focusing of intensive electron beams in helix TWT with PPM focusing system with nonsinusoidal field

Abstract

Experimental results on beam transmission of intensive electron beams in high-voltage TWT with PPM focusing system with nonsinusoidal field at great values of magnetic field parameter α are presented. It is shown, that at 1,01,4, which correspond to the second region of stability, conductance is 82% in statics and 75% in dynamics.
