TuMaG: un magnetógrafo para Sunrise III

After the scientific success of the two first flights of the Sunrise stratospheric balloon mission, the international consortium led by MPS (Göttingen, Germany) decided to re-issue the mission for a third time. For Sunrise III, a new gondola and navigation system will be provided by APL (Johns Hopkins University, MD) and the re-furbished telescope by MPS. The latter also provides the instrumental platform and the light distribution system while KIS (Freiburg, Germany) is responsible for the correlation wavefront sensor in charge of stabilizing the image in real time.

Three new instruments are being developed which will be fed by the telescope. SUSI (Sunrise Ultraviolet Spectropolarimeter and Imager) is an UV, slit spectropolarimeter covering the spectral-line-rich region up to 300 nm. It is being developed by MPS with contributions of NAOJ (Tokyo, Japan). SCIP (Sunrise Chromospheric Infrared spectra-Polarimeter) is an infrared slit spectropolarimeter able to observe in two spectral regions around 768.5 and 851.5 nm. The instrument is being developed by NAOJ and S3CP (the Spanish Space Solar Physics Consortium led by IAA-CSIC). Finally, TuMag (Tunable Magnetograph) is a new magnetograph and tachograph, able to image the polarization properties of two out of three spectral lines in the visible: Fe I @ 525.02 and 525.06 nm; and Mg Ib2 @ 517.3 nm. Inheriting technologies from the former IMaX instrument, TuMag is the first line-tunable aerospace magnetograph. It’s being developed by S3PC. In this talk, I’ll give some hints of the scientific and technical capabilities of the instrument.
