    Hi all.
    I need your help with the project of mine, in which I wist to experiment with High voltage, low current DC impulse spark discharging over a spark gap. I will be using a very high voltage in my circuit (3-4 kV, maybe more) and need help with a switching circuit. I plan on using vacuum triode as a main circuit switch to control a frequency of discharges. The main idea is to apply a large enough negative voltage on a triode grid to stop current flow. Also I am planing to use LTC1799 microchip for impulse frequency generation. It will be used to apply that negative voltage from before.
    Now for my questions:
    1) What approximate triode will work for me?
    2) How can I do that LTC1799 will provide a large enough stoping force for main current flow?

    I appreciate your thoughts on this.
    With regards,
