Dan,

You probably already know this, but at 45Kv you will
be extremely likely to encounter corona loss issues
and related problems such as interturn arcing in your
primary coil.  You will probably want to design the
primary with this in mind, and provide for additional
insulation/clearance than would generaly be used in a
conventional coil.  Just thought I would bring this up
before the plethora of other messages come in
reminding you of this.

I assume you've seen Marco's Thor project.  You might
want to try and talk to him.

later.
