Article "Summarized proposal of a progressive thermalization fusion reactor able to produce nuclear fusions with a mechanical gain superior or equal to 18" Rev. B

Abstract: the main advantage of this fusion reactor is that the plasma after having been brought up near to the optimum conditions for D/T fusion (around 68 keV), is then maintained in this state, low energy non-thermal ions (=15 keV) being injected as replacement ions. So the energetic cost is low and the mechanical gain (Q) is elevated (=18), the working being continuous. Moreover, the main plasma control by the particles injectors (I and U) is relatively simple. This reactor has been partly checked on a simulator.

Article "Progressive thermalization fusion reactor able to produce nuclear fusions at higher mechanical gain" (published in the journal "Energy and Power Engineering":
https://doi.org/10.4236/epe.2022.141003)

Abstract: in the standard fusion reactors, mainly tokamaks, the mechanical gain obtained is below 1. In the other hand, there are colliding beam fusion reactors, for which, the not neutral plasma and the space charge limits the number of fusions to a very small number. Consequently, the mechanical gain is extremely low.

The proposed reactor is also a colliding beam fusion reactor, configured in Stellarator, using directed beams. D+/T+ ions are injected in opposition, with electrons, at high speeds, so as to form a neutral beam. All these particles turn in a magnetic loop in form of figure of “0” (“racetrack”). The plasma is initially non-thermal but, as expected, rapidly becomes thermal, so all states between non-thermal and thermal exists in this reactor. The main advantage of this reactor is that this plasma after having been brought up near to the optimum conditions for fusion (around 68 keV), is then maintained in this state, thanks to low energy non-thermal ions (<=15 keV). So the energetic cost is low and the mechanical gain (Q) is high (>>1). The goal of this article is to study a different type of fusion reactor, its advantages (no net plasma current inside this reactor, so no disruptive instabilities and consequently a continuous working, a relatively simple way to control the reactor thanks to the particles injectors), and its drawbacks, using a simulator tool. The finding results are valuable for possible future fusion reactors able to generate massive energy in a cleaner and safer way than fission reactors.
