Solar XUV grazing incidence spectrograph on Skylab.
Skylab S020 obtained solar extreme ultraviolet and soft X-ray spectra using a novel spectrograph. Despite mission challenges and reduced sensitivity from contamination, valuable spectral data was acquired.
Area of Science:
- Solar physics
- Astronomy
- Spectroscopy
Background:
- Previous solar spectrum data in the 10-200 Angstrom range was limited.
- Skylab missions provided opportunities for extended solar observation.
Purpose of the Study:
- To obtain more complete solar extreme ultraviolet (XUV) and soft X-ray spectra.
- To analyze the solar spectrum between 10-200 Angstroms using long exposure times.
Main Methods:
- Utilized a grazing incidence spectrograph with photographic recording.
- Employed a novel split-ruled grating (1200- and 2400-1/mm) for enhanced spectral coverage and analysis.
- Leveraged long exposure times afforded by the Skylab mission.
Main Results:
- Acquired useful solar spectra in the targeted extreme ultraviolet and soft X-ray range.
- Experienced significant reduction in instrument sensitivity.
- Identified contamination from the spacecraft cooling system as a probable cause for sensitivity loss.
Conclusions:
- The Skylab S020 experiment successfully gathered valuable solar spectral data.
- Instrumental challenges, particularly contamination, impacted data quality and sensitivity.
- Despite limitations, the study contributed to understanding the sun's XUV and soft X-ray spectrum.
