if charges are to be synchronized to within nanoseconds, then really we’re looking at carrying capacity of the wires in terms of high frequencies. to get the sharp-enough rise times needed to even measure a discrepancy, skin effects are therefore significant.
skin penetration depth in Cu @0.1ns is ~.65 micrometre. if you want current to rise from 0 to 2.3 MA in 0.1ns, then this constrains the diameter of your conductors to sizes much larger than i see in photos.
a 13.5 cm diameter copper pipe will rise to full current in 10 ns. is this good enough?
