Abstract

Abstract:

A vacuum ultraviolet VUV spectrometer with spatial and temporal resolutions was presented in this paper. The sensitivity of the spectrometer has been calibrated in situ by using the VUV bremsstrahlung continuum radiation of the HL-2A plasma. The sensitivity coefficients of two gratings were given. The absolute density profile of carbon radiation was thus obtained based on the absolutely radial profile measurement of carbon radiation.

Key words: Tokamak, VUV spectroscopy, Absolutely calibration

摘要：

介绍了HL-2A装置上具有时空分辨的真空紫外光谱测量系统，并首次利用等离子体自身的轫致辐射对该系统测量的光谱强度进行了绝对标定，给出了两套光栅从300~3200Å范围的绝对标定系数，并对等离子体中主要杂质C的辐射分布进行了绝对测量，得到了CⅤ线辐射的绝对强度分布。
