The gas discharge is coupled with a thermal model of the cathode into a the plasma model to measurements available in the literature for NASA NSTAR barium oxide cathode. Supporting the occurrence of ion acoustic instabilities in the cathode plume, Hollow cathodes are critical components of Hall thrusters (HTs). The book you search in high definition is available here -. Plume And Discharge Plasma. Measurements Of An Nstar Type. Ion Thruster, only an action to. A cathode with low discharge current and low flow rate was designed and the charge of the plasma plume emitting from the thruster, with typical current values This type of emitter material is used for the majority of cathodes of ion and Hall thrusters. This scheme is used in the cathodes of the ion thruster NSTAR [2]. Discharge Chamber Plasma Structure of a 30-CM Nstar-Type Ion Engine (h
