Got myself some capacitors for $10 apiece.

The specs are 22 kV, 1 uF, discharge capacitor. See
http://igor.chudov.com/tmp/cap.jpg

The seller was wrong in describing them as 22 VOLT capacitors.
They are 22 KILO volt capacitors. (the seller is Fermilab).
They are similar to this one:

but have twice more capacitance.

Anyway, here is my question. I have a 9 kV DC power supply. (a
Franceformer). How can I safely test these caps before selling
them. At 22 kV, they can store about as much energy as a .22 bullet,
according to my calculations.

It would be less at 9 kV, but still, obviously, very deadly.

So. What is a safe way to charge them, verify that they hold the
charge, and then DIScharge them at 9 kV.

Ignoramus, I strongly protest your post. Here is an interesting
conversation that you started, with 32 posts so far, according
to the Google usenet archive, of which you have made 14, or 44%
of the posts. Yet you marked all your posts "do not archive" -
which means they will be removed from Google Groups in 6 days,
thereby severely damaging the stored thread. With this kind of
callous action on your part, one wonders why others should even
take part in the already-broken, soon-to-be-bogus conversation.
What the h____ are you doing here?
