Description

The resonance on the harmonics of the electron cyclotron frequency in a magnetic field with an extremum was examined. The absorption coefficients of the electromagnetic waves at an electron cyclotron resonance are calculated allowing for the different widening mechanisms for the second harmonic, and the results previously obtained for the first harmonic are analyzed. The absorption of the waves of one resonance in the vicinity of the magnetic field extrema is indicated. The coefficients of absorption does not depend on the widening mechanism and can be expressed in one single analytical relation. The possibility of using the results obtained for the local measurements of plasma density, the distribution function of electrons and the value of the magnetic field in the adiabatic traps, is examined

Abstract (French)

On a examine la resonance sur les harmoniques de la frequence cyclotronique electronique dans un champ magnetique dont la valeur presente un extremum. On effectue le calcul des coefficients d'absorption des ondes electromagnetiques a une resonance cyclotronique electronique en tenant compte des differents mecanismes d'elargissement pour la deuxieme harmonique; on analyse les resultats precedemment obtenus pour la premier harmonique. On indique l'absorption des ondes d'une resonance au voisinage des extrema du champ magnetique. Le coefficient d'absorption ne depend pas du mecanisme d'elargissement et peut etre exprime par une seule relation analytique. On examine la possibilite d'utiliser les resultats obtenus pour les mesures locales de densite du plasma, de la fonction de distribution des electrons et de la valeur du champ magnetique dans des pieges adiabatiques
