Abstract:
The plasma discharge characteristics and different discharge modes of BaW hollow cathode are systematically studied via experiment in this paper. During the experiment, the relevant discharge parameters of hollow cathode working in triode configuration were adjusted, and the discharge characteristics, the possible discharge modes and the transition between different discharge modes of BaW hollow cathode were analyzed in detail. The conclusions that the BaW Hollow ca- thode has three distinct discharge modes (plume mode, spot mode and diffuse mode) were acquired at the end. The three modes can be clearly distinguished by the change of discharge current, discharge voltage and their oscillation characteristics. Furthermore, the transition among the three modes can be realized as the discharge parameter changes.
