Abstract :
The numerical method Transmission Line Modelling has been used to determine the microwave characteristics of travelling wave tube helix slow wave structures. The capability to determine the /spl omega/-/spl beta/ diagram, and the Pierce interaction impedances have been demonstrated. The method has been used to determine the optimum tape to gap width for one structure, and to design a low dispersion structure.<>
