Paper Abstract

The Naval Research Laboratory's Middle Atmosphere High Resolution Spectrograph (MAHRS) is included in the experiment complement for the Air Force Space Test Program's Spartan-282 shuttle payload. The major science objectives of the MAHRS experiment are to determine the abundances of nitric oxide (NO) and the hydroxyl radical (OH) between the altitudes of 50 and 150 km, and to measure the diurnal and global variation of these species. The MAHRS instrument is a Czerny-Turner spectrograph fed by a spherical telescope. It's primary measurement objectives are the OH (A E-4" - X2H) 3090 A band and the NO gamma band at 2150 A. The spectral coverage is 1980 to 3091 A at 0.1 A spectral resolution and the field of view is 0.01° X 1.15°. The focal length is 750 mm and the optical speed is f/7.5. The instrument was designed to produce a flat image at the surface of a 15 mm high X 25 mm wide microchannel plate intensified 2-d array detector with a cesium telluride photocathode and 0.025 mm spatial resolution. In this configuration, for every setting of the grating drive, a passband of about 35 A is imaged on the detector. Recovery of the highest spectral resolution is accomplished by image processing the data.
