SPECTROSCOPIC STUDY OF A MAGNETICALLY CONFINED NITROGEN PLASMA COLUMN.
Abstract
The plasma spectrophotometer constructed in 1968 was modified by the addition of a photomultiplier cooling device to improve time resolution and increase the accuracy of the computed values of the relative intensities of the nitrogen spectrum in the magnetically confined nitrogen plasma column. The relative intensities determined were used to analyze the variation in local electron temperature of the singly and doubly ionized nitrogen atoms with respect to magnetic field. The local electron temperature was found to vary with increasing magnetic field reaching a peak temperature of 8.1 electron volts at 4200 gauss. Evaluation of the relative number densities of the two ionic species indicated that the local electron temperature of the column was the local electron temperature of the singly ionized nitrogen atom.
