Hi,
I know air can be made ionized and glow at low atmospehres like in vacuum tubes at high voltages. But is it possible to somehow make a glow discharge(not corona discharge out of leaking sharp edges) at atmospheric pressures?. Except of Ionization radiation- I haven't heared or read of this,? If it is possible what would do it? very HV van de graafs only produce gigantic spark discharges so simple hv direct current can never do it I guess. HV HF transformers also produce mostly spark discharges but a very tiny glow I suspect(?). Could in theory, HV at sufficient high frequency in the radio range at sufficient energy produce a glow discharge or what would happen??
Thanks
