These tubes have a deionization time. If the current stays zero for roughly
the deionization time, then the tube will switch to a nonconducting state.
I would think that the period between zero crossings for a tesla coil LC
oscillation would be faster than the deion time, and the tube would
therefore stay on for the entire oscillation envelope.
But I could be wrong. Depends on the tube. I know the H filled ones are
faster than mercury vapor tubes, but more than that I don't know.
