“…The simulation demonstrates stable transportation of the 3×0.06 A beam at 25-mm distance in the 0.1 mm×2.4 mm tunnel. These parameters are sufficient to provide high-gain, high-power operation of the 0.2-THz TWT with staggered grating SWS [20].…”

“…Distance of 0.2 mm between the cathodes in y-direction has been selected to get 0.8-mm distance between the beamlet axes. This provides effective interaction with the higher-order TE 03 -like mode of the overmoded staggered grating SWS with 2.4-mm beam tunnel width [19], [20].…”

“…In this figure, the total cathode current c I , the collector current col I , and the body current b I are plotted versus the control grid voltage g V . The anode voltage is set to 21.4 kV toprovide synchronism with the forward wave in the staggered grating slow-wave structure designed in[19],[20]. When the grid voltage is below 1000 V, there is a significant beam interception at the anode.…”

“…Due to the size co-transition effect, the transverse dimension of the SWS decreases with increasing frequency, and then the use of large compression ratios for multiple sheet electron beam injections can effectively increase the output power. Several designs of multiple-tunnel TWTs operating in millimeter-wave bands have been proposed [ 15 , 16 ].…”

A staggered vane-shaped slot-line slow-wave structure (SV-SL SWS) for application in W-band traveling wave tubes (TWTs) is proposed in this article. In contrast to the conventional slot-line SWSs with dielectric substrates, the proposed SWS consists only of a thin metal sheet inscribed with periodic grooves and two half-metal enclosures, which means it can be easily manufactured and assembled and has the potential for mass production. This SWS not only solves the problem of the dielectric loading effect but also improves the heat dissipation capability of such structures. Meanwhile, the SWS design presented here covers a −15 dB S11 frequency range from 87.5 to 95 GHz. The 3-D simulation for a TWT based on the suggested SWS is also investigated. Under dual-electron injection conditions with a total voltage of 17.2 kV and a total current of 0.3 A, the maximum output power at 90 GHz is 200 W, with a 3 dB bandwidth up to 4 GHz. With a good potential for fabrication using microfabrication techniques, this structure can be a good candidate for millimeter-wave TWT applications.
