Abstract

An analog computer which solves Abel’s integral equation is described and its application to the side-on spectroscopic study of high-current arcs is illustrated. By its use radially resolved spectra of cylindrically symmetric inhomogeneous sources are obtained with the same speed and simplicity as are spectra of homogeneous sources. Comparison of NI transition probability measurements using this computer with those using conventional numerical radial resolution techniques indicates that the computer errors are negligible.
