Résumé
Abstract

Une puissante méthode d'investigation du transport dans les plasmas consiste à étudier sa réponse dynamique à une excitation extérieure. Cet article décrit les techniques expérimentales et la théorie de base de l'approche dynamique. Ensuite, les résultats essentiels obtenus sur le transport électronique de la chaleur sont décrits et leur interprétation est discutée sur la base des concepts déduits de la théorie du transport électrostatique turbulent. Finalement, de possibles futures extensions de cette méthode sont suggérées.

One powerful way to investigate transport is to study the dynamic plasma response to externally applied small perturbations. This article describes the experimental techniques and basic theory underlying the perturbative approach. It then reviews the most recent results on electron heat transport and discusses their interpretation based on key concepts from electrostatic turbulence theory. Finally it presents some hints for future extensions of the work.
