Webdischarge chamber and neutralizer operating conditions; and (2) adjusting the ion optics voltages over the broad-est possible range of net-to-total voltage for several values of beam current and total voltage. The thruster was operated under manual control for all performance testing. Test data were recorded from Web1 nov. 2024 · An ion thruster consists of two major components: an ion source and a neutralizer cathode that serves as an electron source. Ions from the ion source are accelerated at grids and form the ion beam. The cathode provides electrons at the same rate as the ions are accelerated, to avoid an electrostatic charge imbalance between the … WebIf you avoid the neutralizer altogether, and/or reduce your negative charge by throwing your electron in some other direction which for the purpose of the proposed scenario, let's … ipo facts and figures 2019
