We can obtain the fusion rate by using cross section, ion density, and speed. The cross section is calculated using particle accelerators.
Heating to 25keV plasma is not the same than throwing ions again a blanket because when heating a plasma, not all the energy is used to accelerate ions again ions but also to make rotations and elastic/non elastic shocks. But when heating the shock rate is increased.
My doubt is at the same ion energy level (as example 25keV) what is really the heating efficiency with respect using linear accelerators.
I am interested in the similar study by using particle accelerators. 25keV ions can be obtained easily by DC-acceleration and the efficiency is high, but the motion is directional. Superimposing of 12.5 keV rf modulation on 25keV-DC, Ei = 12.5 ~ 37.5 keV, is possible to make similar motion to thermal random motion used in nuclear fusion reactors. But the efficiency becomes down to several %, and the value becomes lower especially for large-current/power ions. D-D, D-T collisions can be induced by using two or more accelerators, but the efficiency is very low due to only one reaction at one beam-beam collision, in comparison with multi events to induce reaction for random motion in nuclear fusion reactors.
Superposing RF heats up the plasma lowering the efficiency. It is clear that heating plasma is a very bad idea due radiation losses and instabilities.
Electric thrusters used to accelerate satellites works about 25keV also, unfortunately I need to increase it at least 10 times with high density, perhaps I should use a multistage system. I am building five new plasma thrusters to be used in the next Pulsotron-2 test campaign
The future Pulsotron-3 does the same (p+B11 or p+Li6) but using plasma acceleration.
M. Droba, you have a very interesting approach due you should heat to hundreds keV, the problem is that you will have more inelastic/elastic shocks than fusion ones, so you will have a lot of losses. What is the magnetic field level?
That is the right way.
I am working now at room temperature too to check probes.
The interesting thing is how many T is needed to reach ignition after shocks with the 300keV ions
