Electron density distribution in magnetized hydrogen arc plasmas with the ion temperature deviating from the electron temperature

Abstract

The radial distribution of the electron densityne(r) (ne=approx. 1016cm−3) in hydrogen arc plasmas in a strong axial magnetic field is determined by measuring the rotation of the polarization plane of linearly polarized light (Faraday effect). As expected, it is found that the electron density decreases towards the discharge axis, i.e. with increasing temperature, but again rises near the axis. This increase is due to a thermomagnetic effect, the Nernst effect, in cases where the ion temperature is much lower than the electron temperature.
