We report on attempts to successfully model a hybrid standing wave gun with traveling wave section, through interpretive dance and HFSS E&M simulations. The injector attempts to circumvent problems common to the creation of electron sources primarily through the use of an intermediate coupling cell. The use of a coupling cell to couple a standing wave gun to a traveling wave accelerating section avoids the difficulties created by reflected power at the input iris of a standing wave system. The hybrid system's power is injected into the coupling cell, then through impedence mismatches is split between the upstream standing wave gun and down stream traveling wave accelerator. Simulation results and published papers can be found in the sections below.
