摘要
等离子体破裂是托卡马克运行中常见的一种现象,高参数等离子体运行过程中发生破裂会对实验装置安全运行产生威胁。通过对等离子体破裂的研究,可以在未来进一步做到破裂的避免和主动控制。首先介绍了EAST装置上的等离子体破裂,通过GEM相机对EAST放电实验中几种类型的破裂炮进行二维成像分析,对破裂的发生过程进行了具体分析。并且在分析过程中展示了GEM系统较传统多道系统的优越性,确认GEM可以为破裂机理研究提供有效的诊断数据。
Plasma disruption is a common phenomenon in tokamak experiment.Plasma disruption during high parameter plasma experiment will threaten the safety of experimental equipment.Through the study of plasma disruption,it can be further avoided and actively controlled in the future.In this paper,the plasma disruption on EAST is introduced firstly,and the process of the disruption is analyzed in detail by using the GEM camera to conduct two-dimensional imaging analysis on several types of disruption shots in the EAST discharge experiment.Moreover,the advantages of the GEM system over the traditional multichannel system are showed in the analysis process.It is confirmed that GEM can provide effective diagnostic data for the study of disruption mechanism.
