Research on Ridge loaded Ring plane Travelling Wave Tube

Ridge loaded ring plane travelling wave tube is one kind of high power microwave tube,which can operate in relative broader frequency range.The ridge loaded ring plane slow wave sturcture and its modification are studied in this paper.The exprimental results are in good agreement with the theoretical results.The bandwidth of the modification of ridge loaded ring plane slow wave structure is broader than that of its prototype.The two dimensional large signal equation group with PPM focus is given,and the nonlinear phenomena of circuit beam interaction are also discussed,some useful conclusions are drawn.The results obtained in this paper can provide the basis for the design of this kind of travelling wave tube.
