For a copper anode, if the current is treated as a 1/4 sinusoidal rise to 600kA in 2us the skin depth is ~0.18mm.

my intuitive feeling is, that this rise, (DC pulse from 0 to full current), matches the shape of a 1/2 wave better, since skin depth begins at zero, and increases with time.. and that 1 µs is closer to the actual rise time. this would yield somewhat smaller skin depth (~50% less?)

does that make sense?
