electromagnetic pinch effect demonstrator
I've done some searching in the Technology section already, but (as you know) it's huge, and I didn't see anything that was close enough to what I'm looking for except the electromagnetic coil gun.
I want to replicate a demonstrator I saw, once upon a year, at the Smithsonian Institution. A thin-walled metal tube was dropped into the spaces inside two stacked, separated coils, as if it were an axle for a pair of wheels.
A brief, large current was then run through the coils; the induced currents in the tube produced the "theta pinch" effect, crushing the regions of the tube that were within the coils. (The machine was set up to sell the products for a token price; the impressively crushed tube was dispensed as a souvenir.)
I need advice on the type and capacity of capacitor, thyristor, power supply, etc. to employ. Has anyone here built one, or know someone who has?
