Description
The COronal Spectrographic Imager in the EUV (COSIE) was submitted for selection in 2016 under the NASA Announcement of Opportunity NNH12ZDA006O-HPEXMO. The proposal was very highly rated and received Technology Development funds as a Category III selection, in order to address four technical areas. This report documents the successful achievement of the a development efforts in these areas.
1. The analysis tools to be used for recovering unfolded spectral intensities from overlapped slitless spectra produced in one of the two COSIE channels;
2. Demonstration of the ability to produce the high line density blazed reflection grating proposed for the COSIE spectrographic channel;
3. Risk mitigation by further refinement of the system used to point at and track the Sun over the ISS daylight orbits, including the fine-pointing system internal to the instrument. In this report, we present the results of the work done under that funding.
4. Develop the mechanism that switches the instrument channels from COSIE-C to COSIE-S.
