Summary

Story summary

SLAC National Accelerator Laboratory researchers developed a groundbreaking imaging technique using giant X-ray lasers to study high-density plasma instabilities in fusion reactors.
The method captures filament-shaped instabilities at 500 femtoseconds intervals and yields the most detailed description to date.
The study, published in Nature Communications, finds these instabilities generate a magnetic field of 1,000 teslas, comparable to fields in exploding stars.
Further research is needed to explore other plasma instabilities.
