新一代聚变装置等离子体压力创纪录

Core Insights - Zap Energy announced a significant achievement in its latest fusion energy technology, the "Fusion Z-Pinch Experiment 3" (FuZE-3), reaching an electron pressure of 830 MPa, corresponding to a total plasma pressure of approximately 1.6 GPa, setting a new record for shear flow-stabilized Z-pinch devices [1] Group 1: Technical Achievements - The achievement of high pressure is crucial for controlled nuclear fusion, as higher pressure leads to more frequent fusion reactions, moving closer to the goal of energy output exceeding input [1] - The team utilized "optical Thomson scattering" technology to measure the plasma electron pressure, which is approximately double the total pressure due to contributions from both electrons and ions [1] - The high-pressure state achieved can be maintained for about 1 microsecond [1] Group 2: Experimental Data - In the recent FuZE-3 experiments, repeated discharge measurements showed electron density ranging from 3×10^24 m^-3 to 5×10^24 m^-3, with electron temperatures exceeding 1 keV (approximately 11.67 million degrees Celsius) [1] - The design goal of the FuZE-3 is to reach new heights in the "triple product" (density × temperature × confinement time), which is a critical indicator of fusion performance [1]
