本文简略地描述了FY-1装置结构、等离子体基本参数的测量和等离子体位形的调试,初步考察了硬X射线产额与工作气压的关系。实验分析表明,FY-1装置已形成的等离子体环流放电属于逃逸放电。在场成形线圈作被动运行时,通过改变其回路连接方式和外串电感值,可适当调节等离子体平衡位置和位形。MHD平衡计算与实验测量拟合结果表明,等离子体截面可调节为不同截面积和拉长比(k=1.1—1.4)的椭圆。
In this paper, the structure of FY-1, the measurement of plasma basic parameters and the adjustment of plasma configuration are briefly described. The relationship between the output of hard X-ray and working pressure is briefly investigated. Experimental analysis shows that the FY-1 plasma loop current discharge device belongs to the discharge. In the field of forming coil for passive operation, by changing the loop connection and external string inductance, the plasma balance position and configuration can be properly adjusted. MHD Equilibrium Calculation and Experimental Measurement The fitting results show that the plasma cross-section can be adjusted to ellipses with different cross-sectional area and elongation (k = 1.1-1.4).
