In principle, you can have a cold plasma that produces neutrons very well in a pinch. Pinch devices exploit the instabilities to produce non-thermal ions, ions that don’t conform to a thermal distribution. It is of these ions that efficiently produce neutrons. Small PF devices which have temperatures of less than 1 keV can produce neutrons well beyond the expectations of thermal calculations. LPP hypothesizes that their configuration to place a lower limit on the ion energies. If the LPP approach works, energies below 200 keV would not be relevant to the problem. It’s not clear how far the lower limit can be pushed up but the higher the better for p+11B.

you mean that the graph you posted above shows not ion energy, but thermodynamic temperature of thermalized plasma? OK

yes, I see
engineering is much worse than clean pure physics 🙂

Thank you for your explanations!
