Hi Richard,

As you know, I've been discussing Pulse Discharge capacitors with a couple of
manufacturers.  This is in order to get a quantity discount and the best design
possible.

One question arises that I don't have an answer for.  What is the Q of a high Q
primary.  The heart of the question is really this;  When the primary is charged
by one pulse, how long does it take it to ring down?  What is its time constant?
Inquiring capacitor design engineers want to know.  I realize that this will
differ with the construction of each circuit.  I guess what I'm asking is what
is the Q of yours?  Gauging by your video, your would be typical of a high Q
primary, maybe even better than most.  The reason that this is asked of course
is that the better the Q, the higher the resonate rise.  Therefore a higher
voltage rated capacitor is required for a higher Q primary.

Any feedback you can provide would be greatly appreciated.
