Space radiation shielding enabling human travel into deep space

In a call for innovative concepts, NASA rated space radiation mitigation as the “highest priority technology for human spaceflight.” 1 In response, AML developed and prototypically demonstrated ultra-light and expandable superconducting coils as a portable means to deploy extremely large magnets for radiation shielding and energy storage.

Once again, AML has defied the impossible. As noted in published NASA reports, “However, the concept of expandable, superconducting magnets seems to violate all experience with existing superconducting magnets used for research and medical applications. Such (existing) magnets require support structures to avoid even microscopic movements of the superconductor, which are known to initiate quenching of the superconductor (i.e., transitions from the superconducting to the normal conducting state). Since Lorentz forces acting on the conductors in high-field magnets lead to a large”magnetic pressure” similar to forces acting in conventional pressure vessels, support structures of utmost stability are required for these magnets.” 2

AML’s Expandable Coils™ have significantly changed the paradigm of high-field magnets, with configurations that are launchable and deployable using magnetic pressure to expand large diameter coils.
