The plasmoid reaction should get to maximum magnetic confinement as fast as possible before the ions begin to move toward the butt end of the plasmoid.
This ion inertia will maximize the triple product. If some way was found to produce counter rotating plasmoids that feed ions at each other along the same connecting line, that might be a way to increase the triple product. Like a magnetic mirror, each plasmoid would reflect ions at the other plasmoid and confine the ions between them. Such plasmoids pairs exist. They are called Falaco Solitons. Such vortexes form on the wingtips of aircraft. Focus fusion would be well served to come up with a way to produce Falaco Solitons. A double faced FF electrode with a hole in the middle to let the connecting channel form should work. Or a pair of facing electrodes having the cathode spikes of each pair member positions 180 degrees opposite from each other centered on a common center line. This Falaco vortex pairs are connected with a thin connecting channel. Quarks are Falaco Solitons. Here is a way you can demonstrate this vortex pairs for yourself. https://www.youtube.com/watch?v=909o_kbCdFg
