| Outline of Final Research Achievements |
We have fabricated an emitter array by a microfabrication process, measured the voltage-current characteristics of ion beams, and conducted a numerical analysis of the ion beam trajectory using a particle model for an electrospray thruster, which is one of the candidate microthrusters that can be mounded on micro satellites. As a result, we have found that there is a stable region of applied voltages for ion beam extraction and this region is suitable for efficient thruster operation.
