A high-resolution VUV spectrometer with electronic parallel spectral detector

The development of a VUV spectrometer for photoabsorption studies of stable and transient species is described. The instrument is composed of three elements: a background continuum source which is provided by a laser-induced plasma; a commercially available grazing incidence spectrometer; and a detector coupled to an optical multichannel analyzer. Initial tests of the system consisted of observing the emission spectrum of a Ne hollow cathode source, observing an LPP on an aluminum target; and observing the absorption spectrum of an Al film. The spatial resolution of the device in observations of the spectrum of the Ne(+): 2s22p43s 2p to 2s22p5 2p multiplet is estimated near 40 microns. A schematic diagram of the device is provided.
