ELECTRON SOURCE WITH HOT CATHODE SIMULATOR
Paper contains electron source with hot cathode simulator description. Simulator is made using LabView environment and it is based on static model of source. It is developed for different types of filaments used in vacuum instruments in order to enable easy and fast numerical calculations which are very useful in thermionic emission current controller designing process. Simulator, among other things, calculates temperature and electron emission current distribution along filament in steady state.
