Paper Abstract

A high resolution spectrograph has been developed to study thermospheric, ionospheric and auroral airglow processes in the extreme-and far-ultraviolet. The instrument, called the High Resolution Airglow/Aurora Spectrograph (HIRAAS), has been designed to measure the entire airglow spectrum from 500 R to 1550 X at 0.5 X resolution. This spectral resolution is adequate to resolve the fine structure of several atomic and ionic lines and provide partial resolution of the rotational structure of molecular nitrogen bands. The spectrograph employs dual gratings in a modified Rowland circle mount and uses a microchannel plate intensified electrographic detector. The use of electrography provides a large data format, high resolution and high sensitivity. The HIRAAS instrument was designed for sounding rocket flights and has been selected as part of the shuttle deployed Spartan-282 mission. Future plans for HIRAAS include the replacement of the electrographic detector with an electron bombarded charge coupled device (EBCCD) to allow flight on a long-duration satellite mission.
