RE: Small number of turns in primary

<<Who is Finkelstein? Is there a paper by Finkelstein we can study?
Finkelstein is the 10th reference in Jay's paper:
D. Finkelstein, P. Goldberg and J. Shuchatowitz, Rev. Sci. INstrum. 37,
<That coupling coefficient of 0.6 is really high! I don't think that all the
energy was put into the secondary as that would require k = 1. Please give
us more details of Jay's construction.
<I would like to attempt this on a smaller scale. That static gap sounds
efficient, but I could not duplicate it on my own. Also litz wire is really
expensive. I would hope one could get along without that special gap and the
litz wire. It seems that the idea of such a coil would be in some special
geometry of the primary and secondary. Please send details.
Jay just likes to overdo things to make them "Right". There should not be a
problem in using normal wire. Jay is upgrading his gap now to a SSGS.
Before I can give more information I need to talk to Jay. I have some
I need to ask him to learn exactly what he did do. Will update soon.
