If interference is the problem you could try using a common mode
filter whose centre point is connected to the metal of the box at the
point where the leads emerge. How are you circumventing the problem
of a shorted turn? It may turn out also that capacitive coupling of
the interference to the secondary coil which may act as a simple
radiator could kill the idea.
Ultimately the problem may stem from stepped ionization in the gap
which might be impossible to get rid of. By that I mean that the
quantized nature of the current carrying ions could turn out to be a
