The authors describe a photon counting Extreme Ultraviolet (EUV) detector system used in a rocket borne spectroscopic instrument for remote sensing of upper atmospheric composition and temperature. The detector uses a KBr coated microchannel plate (MCP) Z stack in combination with a wedge and strip image readout system. Three separate detector fields of view are used to sense the Earth dayglow spectrum (980A to 1040A, and 1300A to 1360A) and the solar EUV spectrum (250A to 1400A). They demonstrate high gain (2x10/sup 7/) and tight pulse height distribution (35% FWHM), and spatial resolution of --35..mu..m FWHM which is the highest resolution for a wedge and strip anode MCP detector flown to date. The background, image linearity and flat field performance are discussed. Raw spectra from the rocket flight are also presented.
