Record 2 2018-01-05

English

Subject field(s)
  • Thermonuclear fusion
  • Plasma Physics
DEF

[The thermonuclear] fusion in which a fuel capsule is imploded very quickly, so that the inertia of the converging fuel ions allows fusion to occur before the particles can disperse.

CONT

Inertial confinement fusion triggers fusion reactions by igniting a pellet containing fusion fuel using intense laser or ion beams as drivers.

French

Domaine(s)
  • Fusion thermonucléaire
  • Physique des plasmas
DEF

Fusion thermonucléaire produite par l'implosion d'un microballon de fusion inertielle sous l'effet de faisceaux laser ou d'un rayonnement X.

OBS

La fusion est dite ici «inertielle» parce qu'elle ne se produit que pendant le temps très court, résultant de l'inertie des combustibles, qui précède leur dispersion.

OBS

fusion par confinement inertiel; fusion inertielle : termes et définition publiés au Journal officiel de la République française le 30 septembre 2017.

Record 3 2009-04-24

English

Subject field(s)
  • Thermonuclear fusion
CONT

High-speed injection of pellets, composed of frozen hydrogen isotopes and multimillimeter in size, is commonly used for core fueling of magnetically confined plasmas for controlled thermonuclear fusion research. [...] The process and benefits of plasma fueling by pellet injection have been thoroughly documented in the literature.

French

Domaine(s)
  • Fusion thermonucléaire
CONT

Côté alimentation du plasma, on dispose de trois moyens d'injection de combustible dans la décharge : l'injection de gaz[,] l'injection de neutres [et] l'injection de glaçons, qui consiste à injecter de petites billes de deutérium ou de tritium sous forme de glace. On utilise des systèmes qui ressemblent à des pistolets à air comprimé, capables d'injecter les glaçons de deutérium à plusieurs kilomètres par seconde. Le dispositif est complexe, mais conduit à des efficacités de remplissage du plasma bien meilleures que l'injection de gaz [...]
