| 摘 要： | 为在SUNIST球形托卡马克上进行MHD不稳定性控制研究，建立了一套外加n=1径向磁场系统。此径向磁场系统的电源能确保在1ms内达到电流峰值并维持3ms以上的电流平台，并且有快速关断功能。测试表明，此套径向磁场系统可以稳定可靠地提供在真空室中心产生以n=1模式为主的径向磁场，为开展控制MHD不稳定性研究奠定了基础。

| Abstract: | An external n=1 magnetic field system is set up on the spherical tokamak SUNIST, in order to research the MHD instability control. The power supply of this system could steadily and reliably generate a specified discharge, which could reach the highest value in 1ms and keep a 3ms current platform, meanwhile the current could shut down instantly. Experimental results demonstrate that this system could create a majority of n=1 mode magnetic field at the centre of vacuum chamber, which is an essential foundation for the researches of controlling MHD instability. |
