Emission spectrometry for discharge plasma diagnosis

Spatially-resolved observation of the excitation temperature in a glow discharge plasma for atomic emission spectrometry.

A two-dimensionally imaging spectrometer system was employed to obtain the spatial distribution of the excitation temperature in a glow discharge plasma for emission analysis. A Grimm-style glow discharge excitation source, whose hollow anode had an inner diameter of 8 mm, was observed over the whole emission area. The mapping of the excitation temperature was conducted by using a two-line meth...

Spatially-resolved observation of glow discharge plasma for atomic emission spectrometry.

An imaging spectrograph equipped with a CCD detector was employed to measure two-dimensional emission images from a glow discharge plasma in atomic emission spectrometry. The emission images at Zn I 334.50 nm for a zinc sample and at Cu I 324.75 nm for a copper sample could be obtained. Their emission intensities were not uniform in the radial direction of the plasma region but became weaker at...
