测量从真空紫外线(VUV)到软X射线的光谱是诊断聚变等离子体磁约束等离子体中杂质行为的重要手段。最近，为了同时观测150-1050A波长范围内等离子体辐射的空间和时间分辨率的平场掠入射真空紫外光谱仪，在高能加速研究组织的光子工厂的光束线11C和光束线12A上进行了绝对定标实验。测量了真空紫外光谱仪在P偏振光和S偏振光条件下的绝对灵敏度。
Measurement of spectra in the wavelength range from vacuum ultraviolet (VUV) to soft x ray is an important means to diagnose impurity behavior in magnetically confined plasmas used in fusion plasmas. Recently, a space- and time-resolving flat-field grazing-incidence VUV spectrograph was constructed for the simultaneous observation of spatial, temporal, and spectral distributions of plasma radiation in the wavelength range of 150–1050 A. Absolute calibration experiments were performed at beamline 11C and beamline 12A in the Photon Factory at the High Energy Acceleration Research Organization. The absolute sensitivity of the VUV spectrograph was measured under both P and S polarized light conditions.
