Scientific paper

For solar and heliospheric physics, energy release mechanism of solar flares and onset of CMEs are one of the most the most important issues. Solar Magnetic Activity Research Telescope (SMART) in Hida observatory Kyoto University aims to investigate the relation between the solar flares and photospheric vector magnetic field. Full disk high resolution H-alpha images as well as and photospheric vector magnetic field using Fe I 6302 line have been taken regularly since 2005. In order to improve the vector magnetic field measurement accuracy, a tandem Fabry Perot Stokes polarimeter is newly constructed for the SMART. The system consist of a tandem FP with FWHM of ~0.01nm, polarization beam splitter and two CCD cameras taking orthogonally polarized images simultaneously. In this poster we present the system design and laboratory test results, and expected observational capabilities. We also present the flux emergence activities observed with SMART and Hinode satellite.
