I would like to create an experiment where I would hold ionized air molecules. Most likely negative O2-1 ions. I am looking for the most appropriate enclosure so that the ions do lose as little of charge to the surroundings as possible. I couldn't find any suggestions... Any help would be greatly appreciated.

The ions will neutralize with anything they touch so you would need to hold the ions in place in contact with only other negative objects

$\begingroup$ Do you think that if I connect a conductive chamber walls to a negative voltage terminal with high voltage it might work? I know that the coulomb's law would effectively prevent them from touching the walls in this case but would negative voltage equate to a negative charge? $\endgroup$ Commented Apr 24, 2019 at 7:02

$\begingroup$ Do you think that I could store negative ions in a chamber that would be effectively a Van der Graff generator? $\endgroup$ Commented Apr 24, 2019 at 7:38

$\begingroup$ You would not want negative voltage in the sense of alternating current, you would want negative charge. In the sense that a battery has a positive and negative terminal. $\endgroup$ Commented Apr 29, 2019 at 22:30

$\begingroup$ Yes a van der graff generator would keep ionized air as long as it's on as it would constantly be discharging itself. A better solution would a capaciter wich stores ions for a long time with very little dissapation, even years of holding energy with low dissapation. $\endgroup$ Commented Apr 29, 2019 at 22:35
