Re: [TCML] LTR/STR and spark length
Yes, I fully agree with you here. What are your thoughts
on the spacing of the stationary vs. flying electrodes in ro-
tary spark gaps (RSGs), synch or asynch? I've always heard
that it's best to space these as close as your design will allow
without the risk of electrode collision, since they can arc before
the electrodes actually "line up"....

A wide gap increases the voltage to arc the gap (do not doubt this), but
it doesn't mean that the larger bang energy will run more efficiently
across the gap. The gaps ability to process that energy with low losses
is what makes it "good" or "not". Opening the gap is usually a start to
destruction in my opinion. However, if the gap runs hot, the arc voltage
is simply lower and they get away with doing it (meaning not killing the
transformer or cap), but since the arc voltage is lower due to a lower
voltage, no bang energy increase (expect maybe at the first few sparks).
If the gap is adequately design to handle the power, then opening the
spark gap would certainly develop a large bang size and increase spark
length (up until the transformer or cap died which could be seconds or
several minutes of run time).
Temperature, bang energy, and geometry are very important in my opinion
with regards to a static gap of any type (and they are interrelated).
