Abstract : There is a strong need in the tube industry to develop good simulational design tools. An area where this is most evident is multistage depressed collector simulation. This thesis is an attempt to improve this simulation through the development and inclusion of a physically accurate secondary emission model. The model developed in this report includes provisions for various energy primary electrons, as well as various angles of primary impact. The model developed in this manner was then tested by making calculations on an existing traveling-wave tube. Keywords include: Traveling wave tubes, Multiple depressed collectors, Computer modeling, Secondary emission.
