Crystal Shielding for Space Radiation

Completed TRL 2 (started at 1, targeting 2)

Description

Crystals have a periodic lattice structure that incorporates very strong periodic electric fields which are capable of controlling the trajectories of incoming charged particles. Bent crystals can be used to refract or reflect or absorb incident charged particle beams, with typical applications involving single energy (monoenergetic) beams of a fixed charge which are incident on the crystal from a fixed direction (angle). The major hazard to long duration space flight is due to radiation produced from galactic cosmic rays (GCR), which come from all directions, with a wide range of energies and a wide range of charges. The aim of the present work is to write a computer code for an initial design of a crystal shield. Future work will involve refining the code and the design.

Benefits

Space radiation levels are too high to allow for a human Mars mission. Current shielding technologies are unable to solve this problem. A new space radiation crystal shielding technology will be developed with the aim of reducing space radiation to safe levels for a human Mars mission.

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.
