I like the sound of "something strange going on."
Heck, it might be worthwhile to try various mixtures of KCl and NaCl to see if
there is an obvious particular ratio where the sparking is maximized.
Mills uses a pinhole technique for finding UV where he actually drills a sub-mm
hole into the reactor wall with line of sight to the plasma, and mounts and
glues a photocell UV detector chip over the hole - but that is for a vacuum
reactor.
Robin may have experience with this...?

Some of the sparking looks a little too far from the surface of the glass
container to be contaminated by it and there's a lot of sodium spectrum being
displayed. So something strange is going on, I think.
