Abstract

An apparatus is described which can acquire, in less than a second, a spectrally-resolved, spatial profile of the light emitted from a parallel plate, rf glow discharge. This is achieved by imaging the discharge emission onto the entrance slit of a monochromator with its spatial integrity preserved. Then a spatially-resolved image is detected by an optical multichannel detector which is oriented parallel to the entrance slit. Spatial profiles from nonreactive gas discharges demonstrate that the symmetry of an rf discharge can be dramatically affected by the nature of the gas.
