• Note (General): This paper describes the design and fabrication of an extensible ion thruster stand, the tests to demonstrate its functions, and the test results. The purpose of this thruster stand is to improve the vacuum environment for xenon ion thruster operation while allowing easy access for replacing the thruster in a vacuum. To achieve this, the vacuum facility was furnished with a thruster lock chamber, and a gate valve between the vacuum chamber and the lock chamber. After opening the gate valve, the thruster stand moves the thruster from the lock chamber into the vacuum chamber, where the vacuum is higher than in the lock chamber, and tests can then be conducted on the thruster. The extensible thruster stand, together with the lock chamber and the gate valve, can provide both easy thruster access and a high vacuum around the thruster. To demonstrate the advantages of this improved method, the pressures in the main chamber and in the thruster lock chamber were measured, as the thruster position was changed. Also, the thruster performance was measured, as the chamber pressure was changed by feeding extra xenon. Results of these tests revealed that the pressure around the thruster was lowered to one half to one third by using this thruster stand and that evaluation accuracy was improved during thruster endurance tests. Further this vacuum facility was found to be capable of operating two 25 mN thrusters simultaneously or of operating a larger thruster of 150 mN class.; 資料番号: AA0004213000; レポート番号: NAL TR-1198
