SCEPTRE III - An Intense Source of the Spectra of Highly Ionized Atoms

Abstract

The present investigation draws attention to the potentialities of the high-current toroidal discharge assembly, SCEPTRE, as an intense source of the higher spectra. By way of illustration, several new classified lines of Ne IV, V and VI which have been observed in the range 2200 Å to 2300 Å are reported, thus permitting some revision of, and extension to, the analyses of these spectra. The complete F VI triplet 3s3S-3p3P0 has also been observed for the first time. Two new experimental methods of differentiating between the stages of ionization are given. With SCEPTRE, in contrast to conventional sources of spark spectra, gaseous samples are easily introduced into the deuterium plasma. Thus, such a discharge apparatus will be of value in exciting the spectra of the rare gases.
