Outline of Final Research Achievements

The high-precision UV spectropolarimeter for the sounding rocket experiment, Chromospheric Lyman-Alpha SpectroPolarimeter (CLASP), was developed. Then, CLASP was launched by the NASA sounding rocket on September 3, 2015, and succeeded to observe the solar Lyman-alpha polarization for the first time. The ground-based and on-flight polarization calibrations clearly show that the instrument achieved the required polarization precision, 0.1%.
CLASP discovered that the hydrogen Lyman-alpha line is indeed linearly polarized and its polarization has many properties predicted by the theoretical models. However, the polarization in the Lyman-alpha line-center does not show a clear center-to-limb variation, in marked contrast with the theoretical model calculations. This suggests that the plasma structures of the upper chromosphere and transition region are more complex than we expected. CLASP also discovered some indications for the operation of the Hanle effect in the solar transition region.
