Can voltage in a system be higher then excitation voltage

Can voltage in High Frequency system be higher then excitation voltage?
Specifically,
For excitation I discharge capacitor initially charged to 1000V.
The system is a resonator, with several modes, with some gas in it, ; capacitor connected through length of transmission line, and there is a switch.
Closing the switch creates a pulse.
Can voltage anywhere in such system be higher then initial voltage in the capacitor?

Absolutely - particularly in a high-Q (low loss) resonant circuit: http://books.google.com.au/books?id=...cation&f=false

Thank you, you are correct. Voltage in the middle of series resonant circuit can be infinitely high in theory ... I forgot about it.
