High voltage will make sparks, but that's not the same thing as an electron beam.

You might have to do something like what's described in this paper:
http://www.sciencemadness.org/talk/files.php?pid=76343&a...

But you'd have to scale it up to get the voltage that you want, which would probably involve replacing the spiral generator with an appropriately designed and driven air core transformer, and increasing the size of the device to prevent HV breakdown across insulator surfaces.

I'm wondering, are you just looking to make big sparks, or do you need an electron beam?

We just need a high voltage in order to get a short burst of an electron beam. (I think that is a valid answer to that question :P)

I'll look into that! And we have electron emitters and a tube, we're just using the voltage difference to actually accelerate them ;)

Spark created positrons.

According to the following linked paper, relativistic electron beams have also been detected during storms; so maybe it's not the "sparks", per se, that are making positrons, but bremsstrahlung from the high energy electrons?
