The porous emitter thruster has the advantages of simple propellant feeding and multi-site emissions, which miniaturize the thruster size and increase thrust. However, the multi-scale nature, that is, nano- to micrometer-sized menisci on the millimeter-size porous needle tip, makes modeling multi-site emissions difficult, and direct observation is also challenging. This paper proposes a simple model for multi-site emissions, which assumes that the ionic conductivity or ion transport in the porous media determines the ion-emission current. The conductivity was evaluated by comparing the experimental and numerical data based on the model. The results suggest that the ionic conductivity of the porous emitter is suppressed by the ion–pore wall friction stress. Additionally, the model indicates that the emission area expansion on the porous emitter creates the unique curve shape of the current vs voltage characteristics for multi-site emissions.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Featured Article","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"ACKNOWLEDGMENTS\nThis work was partially supported by JSPS KAKENHI under Grant No. JP21H01530, the Canon Foundation, the Advisory Committee for Space Engineering of Japan Aerospace Exploration Agency, Grant-in-Aid for Exploratory Research in the area of human space technology and space exploration, and JST FOREST Program under Grant No. JPMJFR2129.
