【人民日报】中国“人造太阳”找到突破密度极限新方法

Core Insights - The "artificial sun" known as the Experimental Advanced Superconducting Tokamak (EAST) has achieved significant results in physical experiments, confirming the existence of a density free zone in tokamaks [1] Group 1: Experimental Achievements - 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 study analyzed the boundary of radiation instability and revealed the mechanism for triggering density limits, predicting the existence of a density free zone beyond these limits [1] - Experimental results closely matched the predictions made by the PWSO theory, marking the first confirmation of the existence of a density free zone in tokamaks [1]
