Thanks for explaining. Good luck with removing all this gamma radiation from the system before it vaporizes the chamber but not fast enough as to cool the plasma and stop the reaction. I doubt that this sweet spot exists. Thermonuclear bombs exist only because plasma is surrounded by a thick layer of uranium which absorbs and re-emits gamma radiation thus not letting the plasma to cool. And this layer doesn't have to exist for too long. Less than a millisecond is fine to make a big enough bang.
