From your answer, the elementary plasmoids both get bigger and the ions in it collectively gain an azimuthal velocity component. I guess elementary plasmoids form in a characteristic size and at a characteristic pitch in the reference case, ie without angular momentum injection. So given the right amount of stir, the thoroid could merge into a single huge plasmoid ? But, the faster the merging, the better .. because this leaves a maximum amount of time for the creation of fusion reactions before collapse ? However, too much stir would cause elementary plasmoids to fly thru each other or destroy each other upon collision?

What about the 3rd dimension – along the axis ? The thoroid sheath is thin, what determines the thickness ? Could the rate of voltage buildup at the starting line influence the thickness of the slab that ignites into plasma filaments that start running ? I understand that the rundown velocity depends on the geometry, plasma particle’s mass and pressure. What about repeating the helicoidal trick at the end of the runway so to speak ? Tapering to a smaller electrode separation would modulate the local rundown velocities so as to compress the thickness of the slab – and tapering wider would strech the domain in the time window capable of plasmoid formation ?
