RE: [TCML] DC tesla coil

["S&JY" <youngs@xxxxxxxxx>]

I was aware that UV could trigger a gap, so I took care to shield the gaps
from each other.  Uncontrolled transients no doubt are the culprit. It would
work OK at quite low power, but when power was increased, the filter caps
would discharge through both gaps into the primary with scary "bangs"
resulting in the power supply current meter needle pegging violently -- not
a good thing.  The RSG definitely was much easier on the power supply.

could the gaps "see" each other? i.e. did the UV from one gap illuminate 
the other (and trigger it)..

Or could there have been some sort of transient coupling?
