The scientific Instruments on the SUNRISE observatory
Three new science instruments on board
The seeing-free and stable observing conditions in the stratosphere will be exploited by three new scientific instruments. With measurements over a wavelength range from 300 nm to 850 nm we aim to achieve an unprecedented combination of spatial resolution and the accuracy of determining the height stratification of all relevant physical parameters int he solar atmosphere, like temperatures, magnetic field vector or velocities. The three instruments are described here.
Sunrise Ultra-violet Spectropolarimeter and Imager (MPS)
The Sunrise III UV Spectropolarimeter and Imager (SUSI), a grating based spectropolarimeter, will explore the rich near-UV range between 300 nm and 410 nm which is to a large extent poorly accessible from the ground. A multitude of spectral lines combined observed at highest spatial and spectral resolution combined with the stability of the Sunrise III observatory will offer unique opportunities to study the coupling between the various layers of the solar atmosphere.
Tunable Magnetograph (Spanish Consortium)
TuMag is an imaging spectropolarimeter delivering 2D maps of two different layers in the solar atmosphere, the deep photosphere and the chromosphere, at high temporal cadence (2 maps per minute).
SUNRISE Chromospheric Infrared spectroPolarimeter (NAOJ)
SCIP will allow to measure the chromosphere using the well-known Ca infrared line, and combine the information with lines formed in the deep to upper photosphere.
