Hi Kelly,

	Reducing the pressure inside the coil form will increase the chances for
arcing.  Just like in low pressure neon and other lights.  If you could go
down to 10^8 torr or something then it would work but that would be out of
the practical reach for just about all of us.  Putting SF6 or pressurizing
the core or at least being sure it is really dry in there may be a better
path.  However, it really is just easier to make the secondary large (long)
enough to eliminate the problem in the first place.

Cheers,

	Terry
