中国“人造太阳”找到突破密度极限新方法

Core Viewpoint - The "artificial sun" known as the Experimental Advanced Superconducting Tokamak (EAST) has achieved significant results in plasma physics experiments, confirming the existence of a density free zone in tokamak operations [1] Group 1: Experimental Achievements - The EAST device utilizes magnetic confinement to achieve controlled nuclear fusion, functioning as a circular apparatus that locks high-temperature plasma [1] - The research team developed a theoretical model called the Plasma-Wall Self-Organization (PWSO) model, highlighting the critical role of boundary radiation in triggering density limits [1] - The experimental results align closely with the predictions made by the PWSO theory, marking the first confirmation of the existence of a density free zone in tokamak operations [1]
