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 ??Perv, 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.
