The resonant frequency without toroid is 530kHz..

I sorry that I did not express myself clearly enough : I meant to ask 
if you think this would work for a dye-laser's flash-lamp-pulsing..
I'm seeking a cap for this DC-pulsing application and I'm not
sure if that cap would work because it's so "small" - or even
an electrolytic cap.. (?)

I did not even think about using it in a tesla-coil.. 
Except maybe in a DC-powered, pulsed tesla-coil? :)

I don't mean to use one for tesla work..

I fully agree.. In fact, I replied originally to a message that
stated how much worse tesla-coil is for energy transfer than Hertzian
waves and gave them the reference to your writings in the
ftp-site to get the facts.. They started arguing about rf-theory.. :)

I just didn't know the answer for the Faraday's cage question
as I hadn't tried it..

I just can't do else than "believe" before I get my system to
operational condition..
