It's in the form of a 44mm ID two-layer coil, with 64 turns.

I was hoping someone here had done "exploding wire" experiments and
could offer guidance.

My risetime looks great, and the flyback diode is damping the ringing
fine, but I am nervous that at 1kA I'm pushing the wire too hard.
Still, it hardly has time to get hot.
