I was going to post about some work I had done way-back-when (to me), but after reading it, decided it skated a little too close to the NDA.
What I can say is that it was a pulse-discharge system, and the 'this is the highest test setting you can use without destroying your measuring equipment' was 33K joules of energy.
A .45ACP round is about 500-ish joules. A 1/2 oz bullet moving at 900 FPS.
A 20mm anti-tank round is about 50K joules. A 4oz bullet moving at around 3,000 FPS.
I understand the full-power system was a *very* substantial multiple of joules of the highest test setting. I did get to see video of the system tested at full power. It was 'holy cow I just crapped my pants from *watching* the test on *video!* scary.
I'm glad I was in another state.
Imagine 750MCM cables 5' long.
Now imagine the force required to bend them several inches. When each end is thoroughly secured. Those 5' pieces of cable ended up nearly 6' long when removed from the test jig.
There were multiple 750MCM cables in the test rig on the discharge side.
Get across the capacitor bank of the system at full power, and there would be nothing left of you but a bad smell.

Hi Everyone,
Its probably not all that helpful, but if you really want to understand how an electromagnetic rail gun works - and build one, a degree in applied physics coupled with sundry other qualifications will be useful. I have such a degree, which is why I would echo the recommendations made above, to be mighty careful. One of these guns made large would be capable of delivering a substantial payload into orbit around the Earth. Regards John

No prints but interesting railgun.
