WebThe ion thruster 1 comprises one or more (in the example of Fig. 1: two) electron sources, also known in the art as "neutralizers", 4 to the sides of the ion emitter 2 for avoiding an... 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.
