Story summary

Recent experiments reveal that the "beam on effect" has little influence on the critical current of REBCO superconducting magnets when exposed to neutron irradiation in fusion reactors. This breakthrough eases worries for initiatives like MIT's ARC fusion system, enabling progress without added risks. Meanwhile, researchers remain focused on understanding the long-term degradation of REBCO materials.
