Scientific paper

The use of the University of Wisconsin 15-cm-diameter pressure-scanned Fabry-Perot spectrometer to detect and characterize faint optical emission lines from the Galaxy and the earth atmosphere is described, and a more powerful multichannel spectrometer is proposed. The fundamental principles and advantages of Fabry-Perot instruments are explained; the need for higher throughput is pointed out; the gains possible with a multichannel spectrometer are determined; and test results demonstrating the feasibility of multichannel spectrometry with either photomultiplier or CCD detectors are summarized. It is estimated that a multichannel spectrometer mounted at the Nasmyth focus of a 3.5-m or 8-m telescope would have a beam diameter of 10 or 4 arcmin, respectively, making it possible to probe ionized gas in the disks and halos of galaxies at emission measures less than about 1/cm to the 6th pc and spectral resolution 10 km/sec.
