Determining Radiation Hardness of Novel Visible-Blind Photodetectors for UV Astrophysics Applications

Completed TRL 2 (started at 2, targeting 2)

Description

GSFC and industry partners are currently pursuing the development of UV-sensitive, visible-blind SiC and AlGaN detectors, which are ideal for UV astrophysics applications, especially broadband near-UV imaging (200-300 nm, e.g., Swift/UVOT, ULTRASAT, UVEX). We will determine whether these UV detectors are sufficiently radiation-hard for space-based applications by carrying out deep irradiation gamma-ray and proton testing.

Benefits

The radiation test results would strongly motivate additional development of these exciting technologies for space-based astrophysics applications.

How to get involved

This is early/mid-stage (TRL 2) — 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.
