Hi Mike

I'm challaging the traditional concept of getting as close to the secondary 
without having racing arcs.

I have done extensive simulations using distributed coupling that shows that 
one can increase the clearance between secondary and primary and then be 
able to raise the primary wrt the secondary before getting racing arcs and 
achieve a greater overall coupling without racing arcs then when the primary 
is close to the secondary.  The traditional concept requires the primary to 
be lowered wrt the primary to avoid racing arcs and the overall coupling 
suffers.   The idea is to achieve a more uniform coupling distribution then 
what is traditionally done.  Please see the following writeups when 
hot-streamer is up again:

You will need to go to the GerryReynolds directory first to see the real 
document names.  I cant access it right now because hot-streamer is down, 
but there are three parts and the names given are based on memory.
