PROJECT TITLE :

Theoretical and Experimental Research on a Novel Small Tunable PCM System in Staggered Double Vane TWT

ABSTRACT:

In this paper, a novel little tunable periodic cusped magnet (NSTPCM) system is proposed for the aim of realizing low voltage, big current sheet electron beam propagation during a long distance in engineering, which is composed of a series of position-fastened magnet blocks in alignment and freely sliding staggered pole pieces. This reasonably NSTPCM not solely generates higher magnetic field within the axial direction however conjointly realizes more convenient adjustment of magnetic field in the transverse direction. This NSTPCM system has been successfully applied in an exceedingly Ka-band sheet electron beam staggered double vane traveling wave tube. The tested sheet beam transmission potency is % in a 112.seven-mm-length slow-wave structure underneath the condition of beam voltage twenty four.3 kV and beam current zero.8 A. Moreover, the measured output power is W in the vary from 33 to 37.5 GHz, and the maximum output power is 128 W at 34 GHz. This paper provides the muse for the development of sheet electron beam vacuum devices.
