The same coil you saw at the open house, the 24 inch dia one.   It should 
run up to 16 ft when we get the right driver on it.  We didn't push it very 
much --- wanted to see how the coil would hold up for a possible nearly 
continuous application.

IGBTs were the PowerEx series, 1,000 Volt, 1,200 Amp if I recall right.  I 
can't look at the box due to the fact I'm a long way from the shop right 
now.
