Arcs can happen between the grids that can destroy your supply so its well worth looking into this. You have a cool set of equipment there and I look in envy.

It will get cleaned off smooth by plasma ion collisions with the grid. The flare coming out is due to electrons escaping through the largest hole and on very symetrical grids the plume jumps between openings. As vacuum and voltage increase it canges to look like beams through all the hole centres. There is lots of background info on the fusor forums.

I’m assuming these are residue on the grid burning up.

As the plasma pulsated so did the voltage and current reading on the power supply.

Thanks for the suggestion. For the other readers, here is some background on ballast:

Try some resistors in series on the HV line or some inductance. This should make it more stable and be kinder to your power supply. Good work, I follow with interest. Dustin
