设计了适用于靶电子温度T(E)=50 eV-10keV的大螺旋装置汤姆逊散射系统。在10keV以上，实验误差迅速恶化。为了在10keV以上的温度范围内获得可靠的T(E)数据，我们计划通过以下两种方法扩展可测量的T(E)范围。首先，我们在多色仪中多安装了一个波长通道来观察较短的波长区域。下一步，应用前向散射配置是另一种选择。我们估计了使用这两种方法时的数据质量。这两种方法都有望改善T(E)≥10keV下的T(E)数据质量。
The large helical device Thomson scattering system was designed for the target electron temperature (T(e)) range, T(e) = 50 eV-10 keV. Above 10 keV, the experimental error becomes rapidly worse. In order to obtain reliable T(e) data in the temperature range above 10 keV, we are planning to extend the measurable T(e) range by following two methods. First we have installed one more wavelength channel that observes shorter wavelength region in polychromators. Next applying forward scattering configuration is another candidate. We estimate the data quality when the two methods are used. Both of the two methods are expected to improve T(e) data quality at T(e) ≥ 10 keV.
