Resumo
In this paper a dc design procedure of a X-band
traveling-wave tube is described. This procedure consists in
determine the geometry of the electron gun, the periodic
permanent magnetic and the electron collector. It was found that
an electron gun with a 0.26 μPerv, 9.1 kV, 225 mA and 0.6 mm
beam radius without electrostatic beam control was suitable for
this design. The PPM, constructed with samarium-cobalt
magnetics shown a good agreement with theoretical design.
Finally a three stage depressed collector, to recover part of nonused
electron energy and improve the overall electronic efficiency
of TWT, is presented. The simulations were run with Particle-incell
Studio.
