Glad to know that efficiency is improved by the natural sorting from fast to slow ions. Peak ion temperautre is 600 keV or soo, average is somewhat lower–maybe 400-500 keV. Distance ot the coil is a free variable within engineering limits. Key problem is getting fast switches to prevent the energy from flowing back out as the pulse exits the coil. the preliminary very rough calcualtions I have done indicate that more than one stage is needed for high efficiency. Look forward to you simualtion results. What are you using?
Oh, also average ion energy is expected to be around 2.8 Mev per nuclear charge so 5.6 Mev for He, but there will also be about 20% unburned 2.8 Mev p and 14 Mev B11.
