No, Absolutely not! Remember current in a wire or gas or any conducting media is only a function of the number of current carriers passing a given point in a second. Current is charge in motion only! To get the charges in motion from 1 charge to 200 trillion charges, potential is required. I a gas, the number of ions in motion determine the current. The potential they fall through determines the kinetic energy of the individual particles. Current is just a measure of how many of those particles we can force to fall through the potential.

You can't have any current without charges being in motion somewhere and thus a potential gradient must exist. In the case of a thousand amp arc in gas if the potential drop is only 13 volts, that is all the ions have is 13ev of energy. This is about what happens in a huge mercury ignitron when welding 1" thick steel plates. RH

Amperian forces are significant only at extreme currents of 100 amps or more. Major amperian pondermotive forces are rarely encountered under 1000 amps. The lamps in question are just a few amps.

Without detailed data, plasma filament focusing and tunneling are long shots for making a simple arc lamp into a potent neutron source, and probably clutching at straws.
