迈向能量增益的重要一步 新一代聚变装置等离子体压力创纪录

Group 1 - Zap Energy announced its latest "Fusion Z-Pinch Experiment 3" (FuZE-3) achieved an electron pressure of up to 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] - The pressure is a key indicator reflecting the temperature and density of plasma, with higher pressure leading 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] Group 2 - In the recent FuZE-3 experiment, 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) [2] - FuZE-3 aims to achieve new heights in the "triple product" (density × temperature × confinement time), which is a crucial indicator of fusion performance [2]
