ALFVEN-WAVE INSTABILITY [1 record]

Record 1 2015-01-19

English

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

The electromagnetic micro-instability generated when the energy of the particles is larger in the direction along the magnetic field than in the plane perpendicular to the field[.]

OBS

[This instability is] due to the centrifugal force which acts on the plasma flowing along a curved field line causing the whole field pattern to oscillate back and forth.

OBS

Alfvén-wave instability; fire-hose instability: terms standardized by ISO in 1997.

French

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

Micro-instabilité électromagnétique qui prend naissance lorsque l'énergie longitudinale des particules est supérieure à leur énergie transversale[.]

OBS

Cette instabilité est due à la force centrifuge agissant sur le plasma en mouvement le long d'une ligne de force courbée et entraîne une oscillation transversale de toutes les lignes de force magnétiques.

OBS

instabilité d'onde d'Alfvén; instabilité à saccades; instabilité «lance d'incendie» : termes normalisés par l'ISO en 1997.
