Summary

Story summary

U.S. Department of Energy's Thomas Jefferson National Accelerator Facility is testing spin-polarized nuclear fuel in the DIII-D tokamak, the largest in North America, to boost fusion efficiency.
The project aims to determine whether spin polarization endures extreme conditions in fusion devices.
Researchers expect aligning spins to boost fusion probabilities by 50% and energy output by 80% while using less fuel, with final experiments planned by 2030.
