A rocket instrument designed to measure the profile of the 584 A line of helium emitted by the sun, has been constructed. The most original part of this instrument is a resonant absorption cell for use in the extreme ultraviolet. Filled with rare gases such a device allows the spectral analysis of a wide range of line shapes because a very high optical thickness can be reached. The flexibility of the absorption cell method has been demonstrated both by numerical analysis and by laboratory experiment. Although the planned experiment has not been successful yet, it has been proven that absorption cells, can be used for space applications and several have been tested successfully in flight on board rockets.
