| Description |
This paper presents a preliminary design tool for oriced hollow cathodes. Two physical models compose the tool: aplasma model and a thermal model. A time-independent, volume-averaged model has been developed to determineplasma properties in the emitter and orice regions. A Lumped Element Thermal Model has been also developed tocompute temperature distributions and the respective gradients within the main cathode's element. The study, conductedto validate the results of the models, shows that there is a good agreement with values and trends found in the availableliterature. The tool is able to estimate performances of new devices by the calculation of cathode working conditions fordierent geometries given device operating condition and insert material.
