Abstract

To measure the Z(eff) with electron temperature (T(e)) and electron density (n(e)) profiles at the same time and the same position in the KSTAR tokamak, we design a new polychromator for Thomson scattering system that has additional function. The additional function is measuring bremsstrahlung intensity to calculate Z(eff) independent of Thomson signals. For this new polychromator, we design and fabricate a collimation lens set, and interference filter that has center wavelength of 523 nm and 2 nm FWHM. Finally, we change the lenses, detector diodes, and add the bremsstrahlung filter on the KSTAR edge Thomson scattering polychromator. Then this new polychromator was tested by Tungsten light and monochromator.

摘要

为了在韩国超导托卡马克先进研究装置（KSTAR）托卡马克中同时且在同一位置测量有效电荷数（Z(eff)）与电子温度（T(e)）及电子密度（n(e)）分布，我们为汤姆逊散射系统设计了一种具有附加功能的新型多色仪。该附加功能是测量轫致辐射强度以独立于汤姆逊信号来计算Z(eff)。对于这种新型多色仪，我们设计并制造了一组准直透镜以及中心波长为523纳米且半高宽为2纳米的干涉滤光片。最后，我们更换了透镜、探测器二极管，并在KSTAR边缘汤姆逊散射多色仪上添加了轫致辐射滤光片。然后用钨灯和单色仪对这种新型多色仪进行了测试。
