WebHigh-Efficiency Helix TWT’s and Small MDC’s PETER RAMINS, SHELLY PEET, AND DALE A. FORCE, MEMBER, IEEE Abstract-The usefulness of the concept of spent beam refocusing in optimizing the performance of low- and medium-power helix TWT’s equipped with small multistage depressed collectors (MDC’s) is ex- amined. WebTo obtain design objectives mentioned in the second step, it is necessary to have optimum helix slow wave structure (SWS) design parameters such as helix pitch, radius and pitch angle. Therefore, ... The length of the interaction structure of the designed TWT is nearly 110 mm and all design objectives are nearly achieved as it is expected.
