As I said before, Capacitors store charge (Coulombs), not Energy (Joules)...
Of course the charge in the tube does carry energy, so:
Q = C * V
V = E / Q
so E = Q * V = C * V^2...
So assuming your .001 F measurement is correct, and using V=20,000
E = 400,000J Hmmm... that'll keep you warm at night...
