Probable identification of the on-disk counterpart of spicules in Hinode Ca II H observations
A. G. de Wijn
I present a study of high-resolution time series of Ca II H images and Fe I 630.15 nm spectra taken with the Solar Optical Telescope on the Hinode spacecraft. There is excellent co…
Design of a Full-Stokes Polarimeter for VLT/X-shooter
Frans Snik, Gerard van Harten, Ramon Navarro +3
X-shooter is one of the most popular instruments at the VLT, offering instantaneous spectroscopy from 300 to 2500 nm. We present the design of a single polarimetric unit at the pol…
Stray light and polarimetry considerations for the COSMO K-Coronagraph
Alfred G. de Wijn, Joan T. Burkepile, Steven Tomczyk +3
The COSMO K-Coronagraph is scheduled to replace the aging Mk4 K-Coronameter at the Mauna Loa Solar Observatory of the National Center for Atmospheric Research in 2013. We present b…
Preliminary design of the Visible Spectro-Polarimeter for the Advanced Technology Solar Telescope
Alfred G. de Wijn, Roberto Casini, Peter G. Nelson +1
The Visible Spectro-Polarimeter (ViSP) is one of the first light instruments for the Advanced Technology Solar Telescope (ATST). It is an echelle spectrograph designed to measure t…
The chromosphere and prominence magnetometer
Alfred G. de Wijn, Christian Bethge, Steven Tomczyk +1
The Chromosphere and Prominence Magnetometer (ChroMag) is conceived with the goal of quantifying the intertwined dynamics and magnetism of the solar chromosphere and in prominences…
