Popis:	This paper describes the status of the next-generation xenon-ion-engine research at IAT (The Institute of Aerospace Technology). A set of ion extraction grids, which had been pressed improperly in FY2004, was pressed again to obtain the designed shapes after reviewing the pressing process. Another set of ion extraction grids, whose peripheral regions were masked, was manufactured after this. Both results were unsatisfactory and it was finally found that important knowledge had been lost in the pressing process. However, each grid set was tested as a part of an ion thruster. A main cathode continuous operation to confirm the life of an impregnated cathode has begun and is continuing without any symptom of degradation in the cathode. Four neutralizers including two graphite-orifice-plate types were evaluated individually as a part of an ion thruster. One of the graphite-orifice-plate types showed satisfactory characteristics. 資料番号: AA0049500063 レポート番号: JAXA-SP-06-006
