    The number of breakouts was not caused by the size of the toroid as
when we
ran the system with a smaller, duct toroid breakout did not occure, the
multiple
breakouts were due to sharp points on the solder joints of the array. We
decided
on a larger toroid for performance considerations, the maximum arc lenght was
increased around 10-20% by using a larger toroid, we feel that we have
about the
optimum size now as larger toroids still cause a fall off in performance.
 As
for the caps, as far as I am aware they are standard barium titanate types. I
agree that the losses do seem a bit high, but I cannot think of anywhere
else they
may be comming from as we have checked virtually everything else.
