为了研究JT-60等离子体中的杂质行为，研制了一套能同时测量多种杂质离子光谱及其空间分布的光谱诊断系统。该系统由具有不同视线的可互换单元型摄谱仪组成。四种类型的掠入射摄谱仪被制备为单元型摄谱仪。这些光谱仪分别覆盖0.5-5、0.5-50、2.0-50和50-122 nm的标称波长区域，并且具有带平焦场的全息光栅。图像增强型1024或512通道光电二极管阵列用作所有光谱仪的探测器。四个单元型摄谱仪用于观察主等离子体，两个单元型摄谱仪用于观察转向放电零点附近的等离子体。其中一台光谱仪已经在27.5-120 nm波长范围内使用光子工厂（国家实验室）的同步辐射进行了绝对校准。
In order to study impurity behavior on the JT‐60 plasma, a spectroscopic diagnostic system, which is capable of measuring many spectra of impurity ions and their spatial distributions simultaneously, has been developed. This system consists of interchangeable unit‐type spectrographs which have different lines of sight. Four types of grazing incidence spectrographs are prepared as unit‐type spectrographs. These spectrographs cover the nominal wavelength regions 0.5–5, 0.5–50, 2.0–50, and 50–122 nm, respectively, and have holographic gratings with flat focal fields. Image‐intensified 1024‐ or 512‐channel photodiode arrays are used as detectors for all spectrographs. Four unit‐type spectrographs are used for observing the main plasma, and two unit‐type spectrographs are used for observing the plasma near the null point of the diverted discharge. One of these spectrographs has been calibrated absolutely in the wavelength region 27.5–120 nm using synchrotron radiation from the Photon Factory (National Laborato...
