Why can’t there be some kind of ventilation/purification system that maintains the purity level of the plasma? The Russian GIT-21 device mentioned from the Prague conference report was said to have puffed in fresh plasma between its electrodes before firing – so why can’t FF-1 do that too? Fresh plasma is obviously going to be of higher purity than plasma that’s sitting around absorbing more evaporated electrode material.

I like your idea. Can we expand on it? The vaporized electrode ions are much heavier than the deuterium ions. If the fresh plasma is entering the chamber at the same speed as the plasma sheath in the axial phase, then maybe the heavy ions can be left behind because they can’t accelerate as fast as the deuterium ions. Another benefit is the insulator may be exposed to less stress for a shorter time.
