用荧光方法研究了WEGA仿星器中磁通面的真空位形。在实验中，对于Bt=87.5mT的环形磁场强度，旋转变换i在1/9和1之间变化。我们已经表明，WEGA的磁线圈系统产生良好的嵌套磁表面，特别是在低的ι值。然而，在实验中观察到的非天然岛屿所造成的场扰动仍在调查中。实验结果进行了比较，从Gourdonand沃纳代码获得的计算。
The vacuum configuration of magnetic flux surfaces in the WEGA stellarator has been studied using the fluorescence method. In the experiments the rotational transform ι was varied between 1/9 and 1 for a toroidal magnetic field strength of Bt=87.5mT. We have shown that the magnetic coil system of the WEGA generates good nested magnetic surfaces especially at low ι values. However, in the experiments non-natural islands have been observed caused by field perturbations which are still under investigation. The experimental results are compared with calculations obtained from the Gourdonand Werner-code.
