I am wondering if a canister of pressurized oxygen could be used as a fuel source for an ion thruster.
To show how this could work on a conceptual basis, please reference the following drawing:
I believe if this would work, it would be a more cost effective way of generating thrust since it would not require the hardware to generate magnetic fields nor the use of an electron gun, both of which are needed for a standard ion thruster.
Could pressurized oxygen be used as a fuel source for an ion thruster?
I realize now that neutral oxygen atoms would not work. It would have to be a pressurized canister of ionized oxygen with a negative charge, or if ionized oxygen with a positive charge is used, then the electric field grids' polarity would have to be reversed. I have learned that there are machines that produce either ionized oxygen with a negative charge or with a positive charge, yet whether it can be pressurized within a canister, that I do not know.
