Hello Greg.

if i`m not mistaken, about 92% of the start energy is transfered from
primary to secondary, approximately at 4 periods of Fres, and system
operates in mode 6:7 or 7:8 - is it true? what is the Q (unloaded) of
primary & secondary ?

here each stationary electrode has its own insulator, but here:

http://www.lod.org/Projects/electrum/NewZealand/pages/nzrotarygap.html

are they all mounted at the same insulating rod? is bottom left
electrode the last in the chain and connected to the primary?
look here:

http://www.lod.org/Projects/electrum/NewZealand/pages/nzxmsnline.html

is the top left electrode the first in the chain &  connected to the
cap? and two last electrodes at the photo are  connected with the bus
(from the side)? are there only 3 buses - one at the left & 2 at the
right? and why i can`t see neither buses nor electrodes here:

http://www.lod.org/Projects/electrum/NewZealand/pages/nzgapinst.html

are they covered by something from the side?

"with 8 gap in series, the effective opening speed of the gap system
is Mach 3.2, and the total mechanical dwell time is comparable to a
single beat envelope at 38khz, with k=0.22"

ok - imagine that after 1 period of Fres electrodes will go out from
"engagement", and after another three periods they will move at approx
3-x their thickness - then summary gap length will be 6" - it should
be enough for arc disconnection, but in reality this distance would be
smaller. it`s at 350bps, and at 100 - less 2" - will be enough?
i.e. this gap is quenching by itself and it`s not neccessary to connect
other in series with it?  did you try to make something similar, but
in smaller scale - ex. at 10kw? coz the disc`s diameter is too large
for me - 71cm %-)

what was the effective operating impedance of this gap (approximately)?
