Abstract
Two different methods of calculating the small-signal gain of a traveling-wave tube (TWT) based on J.R. Pierce´s standard theory (1950) and the theory of finite beam thickness of K. Ura and M. Terada (1962) are described. Three broadband TWTs were built and tested. The experimental results are compared with the theoretical values calculated by the two methods. The method based on the theory of Ura and Terada shows better agreement with the experimental results. A method for approximating the gain in the terminated loss region is also described
