Web1 dec. 2024 · In order to characterize the operation and performance of the newly designed ion thruster, it was installed together with the PPU in a vacuum test chamber at IOM. The Xe gas was provided by a conventional mass flow controller in this test campaign. The total volumetric flow for ion thruster and neutralizer ranged between 1.29 sccm and 1.58 sccm. 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.
