Gridded ion thruster - Wikipedia
WebA new structure of lanthanum hexaboride (LaB 6 ) hollow cathode insert, which has a cylindrical core, is studied in this paper. The cylindrical core is inserted into and connected at the back of the traditional hollow cylinder part. Two inserts with core and one traditional insert are tested. The new structure can largely reduce the cathode temperature, the gas … Web13 dec. 2024 · The ion thruster expels the ions for a few seconds or minutes (depending on the mission) but after this event the satellite returns to a potential 0, this means that … jonathan fader phd
EP3892853A1 - Neutralizer for an ion thruster of a spacecraft
WebAs the ENPULSION NANO expels an ion current of up to 4 mA, the module needs a method to prevent spacecraft charging. This is achieved by the use of two cold-redundant electron sources acting as neutralizers. Once electrons have left the neutralizer, they will be pulled towards the positive potential of the ion plume. Web17 nov. 2024 · An iodine plasma is created by electron impact ionization using a radio-frequency (RF) inductive antenna, and positive plasma ions are extracted and accelerated by the grids to high speeds (about... WebThe aim of this project was to develop, manufacture, and test a neutraliser for XSEPT, the gridded ion thruster project under development by the University of Southampton. Secondary objectives were to use additive manufacturing to produce components where possible, and to test various designs of the neutraliser components. how to initiate physical intimacy
