Darren -

Don't confuse this with Tesla coils. There are many electrical devices that
produce ultra high voltages. However, a Tesla coil is the only electrical
device that produces ultra high voltages at ultra high powers. This is best
accomplished with dampened sine waves. We still do not know how to optimize
the parameters.

I haven't looked on the web yet, but I thought I would mention something I
saw with my eyes a couple of days ago.

At the Australian National University, Research School of Physical
Sciences and Engineering, there are some glass cases with old creations
that aren't needed anymore. One of the cabinets has a superconducting
conical rod with the smaller end fitted to a toroidal shape but with the
hole axis at right angle to the rod unlike tesla coils where the hole axis
is in line with the coil.

The superconductor is fed it's 1/4 wavelength at the base and it is
claimed that less than 10 W of power is needed to produce over a megavolt
of RF at the toroidal bit. When a charged particle enters the toroid's
hole at the right time it is accelerated to the middle and then repelled
away when the voltage is reversed (needs to enter at the right phase).

Several of these resonators formed a large particle accelerator and they
were probably used in many other particle accelerators too.

If you want to check out their website I can't guarantee that it's there
since I haven't got the time to look, but try www.anu.edu.au and look for
RSPhys.
