Abstract : A multichannel photon counting VUV monochromator is described whose design features high sensitivity, rugged construction within about a 2/3 cu ft volume, and low crosstalk. Discussed also are the details of a careful calibration, as well as the results of a very preliminary analysis of data collected on a rocket flight into an aurora in March of 1981. It is concluded that the basic design of the instrument is valid. In addition, arguments are advanced to support the view that, in spite of the unfortunate use of a high-scattering grating, valid auroral emission rate data may have been collected in the 1325 A, 1356 A and 1384 A channels.
