Yes,Malcolm is right .It was the extra coil of Hull's
magnifier.BTW,I think I had an e-mail correspondence
with Richard where he mentioned that piece.
A voltage of extra coil was estimated by him to be
quite low (~150 KV by my memory) for 10' arcs but BPS
rate was enormous,top electrode as well,thus the power
pushed into the system considerable.
However,as one increases BPS rate and lowers at the
same time bang size, keeping so power always the
same ,at one point arc lenghts will start dramaticaly
to decrease..
One may imagine that final result is CW mode with
rather short arcs but with very fat and bright
structure on the other hand.
It is imposible ,becouse of gas dynamics, to make coil
with top electrode large like house with 50 KV peak
voltage which is capable to throw 10' arcs in standard
atmospheric conditions.
