Ultraviolet polarimeter to record resonance-line polarization in the solar spectrum around 130-150 nm
Abstract
A Swedish-built UV spectropolarimeter to be launched on a Soviet satellite in the Intercosmos series is described. The scientific objective is to record linear polarization across monochromatic solar images formed in resonance lines in the 130-150-nm wavelength region. This polarization arises by coherent scattering in the chromosphere-corona transition region of the sun. The instrument uses two parallel optical channels with highly different polarizing properties. The polarization analysis is done by reflection at gold-coated mirrors. The UV calibrations of the two flight models are described.
