The Tautenburg Solar Laboratory (TauSoL) as Pathfinder for SPRING
摘要
The Tautenburg Solar Laboratory is a new solar observation facility to develop full-disc instrumentation for a new synoptic solar network. In the first phase, a ful-disc spectropolarimeter based on a single tunable etalon placed at the telescope aperture is developed. The development includes a container-based light feed system and optical laboratory, the instrumentation as well as calibration and data reduction pipelines. The ultimate scientific goal is the quasisimultaneous observation of spectral lines for synoptic studies and helioseismic investigations of the Sun.
