Summary: In this paper a new simulator for the design of Traveling Waves Tubes (TWT) electron guns and multistage collectors is presented. The simulator is based on the 3-D FE discretization of the Poisson equation combined with a particle model for the solution of the Vlasov equation in the space charge limited regime.
