The supersonic implosion approach was shown to be unworkable for at least two reasons (the shock wave hitting the pusher/gas boundary broke into a forest of jets due to the Richtmeyer-Meshkov instability, and the currents in the surface of that pusher [ignoring the instability] would have been so high the push surface would have been vaporized, contaminating the plasma.)

So they changed to a subsonic approach, and also moved to a spherical tokamak arrangement. This means the target now has a solid conductor running down the central axis, and this conductor would be exposed to utterly hellish levels of neutrons (orders of magnitude worse than conventional fusion reactors) as well as forces from 100T magnetic fields. I have no confidence this could be made to work, even for a single shot. Also, in subsonic implosion, there is pressure equilibrium in the pusher, so the outside of the chamber feels the same extreme pressure as the inside. 100T gives a pressure several times that of the bottom of the Marianas Trench.
