Zap Energy's FuZE-3 Sets Record Plasma Pressure in Fusion

Summary

Story summary

Zap Energy's Fusion Z-pinch Experiment 3 (FuZE-3) achieved record plasma pressures of 830 MPa, about 1.6 GPa, the highest in a sheared-flow-stabilized Z pinch.
The results were presented at the American Physical Society’s Division of Plasma Physics meeting.
FuZE-3 uses a third electrode to independently control plasma acceleration and compression, signaling progress toward scientific energy gain (Q>1) and a next-generation FuZE system planned this winter.
