Abstract

We are currently developing an instrument free from optical components to measure the full-disk solar spectrum in the extreme-ultraviolet (EUV) regime covering wavelengths from 75 to 400Å. The instrument consists of a windowless noble gas ionization cell followed by a toroidal electrostatic analyzer to spatially disperse photoelectrons as a function of their energies. A microchannel plate based position sensitive detector is used to detect individual electrons, indirectly returning the solar EUV spectrum. The instrument was launched aboard a NASA Black Brant sounding rocket on October 27, 1992. Power to this instrument was lost early in the flight, however, and a reflight is planned for October 1993. Calibration results for the He II 304-Å line are presented.
