English

Subject field(s)
  • Energy Transformation
  • Thermonuclear fusion
  • Atomic Physics
DEF

Group of electrostatic macro-instabilities which resemble the universal modes but whose growth rate is connected with collisions rather than with resonant particles. [Definition standardized by ISO.]

OBS

This instability is due to the fact that the potential and density fluctuations are put out of phase by collisions and this generates a growing wave.

OBS

drift-dissipative instability: term standardized by ISO.

DEF

Groupe de macro-instabilités électrostatiques qui ressemblent aux modes universels mais dont le taux de croissance est lié plutôt aux collisions qu'aux particules résonantes. [Définition normalisée par l'ISO.]

OBS

L'instabilité est due au fait que les fluctuations de potentiel et de densité sont déphasées par les collisions, ce qui engendre une onde croissante.

OBS

instabilité dissipative de dérive : terme normalisé par l'ISO.
