Advancement of High-Resolution Gamma-ray Spectrometer

Completed TRL 5 (started at 4, targeting 5)

Description

We are developing a high-resolution gamma-ray spectrometer for the purpose of studying solar flare gamma-ray line emission in the ~0.5-10 MeV range. We are employing a cutting edge CeBr3 scintillator which has high photoelectric effect cross sections in the MeV range read out by silicon photomultipliers. We will use the high-heritage readout electronics built for the BurstCube mission updated for CeBr3 signals. The primary effort will be to update the readout electronics and signal processing to be suitable for the CeBr3 signals.

Benefits

This effort is in support of a future mission concept for which our group is supplying an MeV solar gamma-ray spectrometer. The use of CeBr3 crystals will significantly increase the energy resolution of the detector and provide novel insight into MeV gamma-ray line emission in solar flares. We have also partnered with researchers in astrophysics and planetary science as the development of this technology would be useful for the study of MeV gamma-rays in a variety of astrophysical contexts.

How to get involved

This is early/mid-stage (TRL 5) — 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.
