SUSI: TV test of flight components
The first TV test of the SUSI flight components was successfully completed. The grating mechanism, the scan mirror and the filter wheel performed as expected.
SUSI mechanical flight components in the big thermal vacuum chamber at MPS.
In June 2020 some important flight components of the SUSI instrument were tested in the big thermal vacuum chamber at MPS. These components are crucial for the operation of the SUSI instrument: The grating mechanism allows to select any wavelength window between 314 and 410 nm during the flight, the filter wheel selects the matching pre-filter, and the scan mirror allows for obtaining maps of the solar surface by moving the image over the entrance slit of the spectrograph.
All tests were completed successfully.
