Radio-frequency biasing of ion acceleration grids - IOPscience
WEBDec 24, 2018 · As long as the applied RF frequency is sufficiently high, reasonable grid dimensions can be found to allow for efficient ion extraction from the plasma source with no direct impingement of the accel grid, and with inherent plasma source current compensation and ion beam space charge compensation.
Radio-frequency biasing of ion acceleration grids with different ...
WEBMar 9, 2022 · When a radio-frequency (RF) voltage is applied across the grid system instead of a direct-current voltage, the simultaneous extraction of ions and electrons is achieved, thereby a neutralizer is not required.
Schematic of a gridded ion source using RF biasing of the …
WEBElectrons neutralizing the ion beam from a gridded ion source are typically provided by an external cathode. This cathode emits a continuous current that ensures quasi-neutrality of the plume,...
Gridded ion sources: Is there RF leakage to grids?
WEBDec 1, 2021 · Let's take a look at a simplified image below showing typical 3-grid RF ion source construction. On the practical side - I would assume that some of RF excitation energy will be picked up by grid(s...
WEBradio-frequency (RF) voltage is applied across the grids, and a capacitor is added to the external circuit, both electrons and ions can be extracted from the thruster and a neutralizer is no longer needed.
Ion flux–energy distributions across grounded grids in an RF …
WEBAug 10, 2022 · We present an experimental investigation of the ion flux–energy distribution functions (IFEDFs) obtained across grounded grids in an asymmetric capacitively coupled RF source using a helium discharge.
Gridded RF Ion Sources - Veeco

RF Gridded Ion Thruster Design for Laboratory Experiments
WEBJan 18, 2024 · This work presents a basic overview of RF ion thruster concepts, ICP operating principles, antenna matching, and thruster design for new users. A lab model RF gridded ion thruster...
WEBAbstract: A gridded electric thruster that operates with only one RF power source providing propellant ionization, ion acceleration and beam neutralization is described here. Acceleration of both ions and electrons is achieved by a single set of extraction grids and the system is therefore neutralizer-free.
