SPECTROSCOPIC MEASUREMENT OF THE MAGNETIC-FIELD IN A HIGH-DENSITY PLASMA

It is demonstrated that a magnetic field determination is possible by spectroscopic measurements for a dense plasma at an electron density of 1018 cm-3 produced in a z-pinch discharge. For this purpose, polarization effects on the Hα-line are analysed. The emission line itself cannot be used for the investigation because, at these high densities, its half-width is of the order of 100 Å. It is found, however, that the field strength can be deduced from the absorption line properties. © 1979.
