Hi,
of all the main plasma heating techniques employed by multiple fusion reactor designs, namely
1) ohmic heating
2)RF
3)neutral beam
4)some other method?
Which of them is the most efficient in terms of how much of the input electricity gets converted to direct heat/kinetic energy of the plasma particles percentage wise?
Also if we could somehow (for the sake of the argument magically) achieve a much higher gas and resultant plasma density/pressure and still contain it with EM and B fields could we get to much higher fusion temperatures by simply using ohmic heating?
Imagine a sort of gas discharge tube scenario where we have a container filled with high pressure D-T and we have a low voltage high current source and a high voltage starter , we start an arc or ionization channel through the gas by the HV and then the low voltage high current "burns" for some time and creates large temperatures and pressures, I wonder what would be the maximum particle energy achieved in such a way ?
