Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)

The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) will observe the Sun in the 6-24 Angstrom wavelength range with 6 arcsec resolution along the 8 armin slit. The data will be used to determine the frequency of heating in the solar corona and the FIP bias in different hot coronal structures. This information can be used to discriminate between coronal heating mechanisms and fractionation mechanisms that cause the FIP effect. MaGIXS is composed of three subsystems : an X-ray telescope, a spectrograph, and a detector. The X-ray telescope optic will produce focused images on a slit; a slit jaw imaging system will be used for pointing and data alignment. The spectrograph consists of a collimating and re-focusing pair of corrective X-ray optics and a blazed grating. The detector is a low-noise, fast-readout camera. The alignment of the system will occur in stages, with the final alignment at the Marshall Space Flight Center Stray Light Facility.

Support NASA's Heliophysics strategic science objectives to understand the Sun and its interactions with Earth and the solar system, including space weather. This will be achieved by developing/demonstrating instrumentation technology necessary to address the following science goals: Explore the physical processes in the space environment from the Sun to the Earth and throughout the solar system; Advance our understanding of the connections that link the Sun, the Earth, planetary space environments, and the outer reaches of our solar system; Develop the knowledge and capability to detect and predict extreme conditions in space to protect life and society and to safeguard human and robotic explorers beyond Earth.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
