Abstract :
If the optimum performance of a folded waveguide travelling wave tube (FWTWT) is to be achieved, then choosing the correct dimensions for the electron beam tunnel is critical. In this abstract, we consider some of the factors that affect this choice, and suggest an optimum tunnel diameter.
