Summary

Electron temperature and density were measured in the rotating magnetic field pinch by means of laser light scattering. The results are compared with previous measurements and with numerical calculations based on a three-fluid magnetohydrodynamic model. The comparison between theory and experiment shows that the interior surface of the discharge tube acts as a plasma source producing approximately 0.6*1015 electron-ion pairs per cm2 per μs.

Zusammenfassung

Elektronentemperatur und Elektronendichte wurden im ”Rotating magnetic field pinch”—Experiment mit Hilfe von Laser-Licht Streuung gemessen. Die Resultate werden mit früheren Messungen und mit numerischen Berechnungen verglichen. Für die numerischen Berechnungen wurde ein magnetohydrodynamisches Dreiflüssigkeitsmodell verwendet. Der Vergleich zwischen Theorie und Experiment zeigt, dass die Wände des Entladungsrohres eine Plasmaquelle darstellen, die etwa 0.6*1015 Elektronen und ebensoviele Ionen pro cm2 pro μs erzeugt.
