My father was chief engineer at PacCar for 40 years and designed a lot of guns and vehicles. But he was just another of zillions of guys paraded past the Star Wars build up railgun demonstration. Then in 1994 I was at an amateur lab [warehouse in Seattle now a fancy REI store] with artists and engineers trying to think of something crazy to do. Someone bought some star wars surplus capacitors from a rail gun. I have been designing power supplies and battery chargers for a long time, and these are special capacitors. They are low effective series resistance, low effective series inductance, and high Voltage. In other words, these are more like ideal capacitors than capacitors you can buy, for reasonable prices. So they charged them up with a Neon light transformer and diode stack, and connected with an air powered long solenoid switch and fired a rail gun. Then they did the same thing, but to fire a steam gun. Then they put a coil around a tin can and shrunk it. Then they put a coil around a coin and shrunk it. Everyone there wanted a shrunk coin. ![[Linked Image]](http://i757.photobucket.com/albums/xx220/ClarkM/Quartersoneshrunk.jpg) It sounds like dynamite and sends pieces of wire like bullets, so don't try this at home, kids.

There was an article in Guns and Ammo or Shooting Times in the mid to late '60's that showed the damage little nylon discs about the size of an aspirin tablet would do on metal at ultra hi velocities (electronic rail gun IIRC). The craters looked a lot like the one someone posted earlier. Seems like they were a couple of inches deep and the same across.

High energy photons can excede the speed of light and disappear on impact.

The high 2200 cyclical rate of the ARC is worth bonus points allowing the relatively slow 5k MV extra damage points.

Electrodes. Good luck trying to use tugsten as a filler rod.
