为了开展托卡马克装置边缘相关物理问题的研究及汤姆逊散射对电子温度、电子密度更为精确的测量,初步建立了具有高时空分辨的近红外轫致辐射测量系统,并测量了其在不同加热条件下的近红外轫致辐射信号。通过与可见光波段及X射线的轫致辐射信号进行对比分析,验证了系统的可行性。该诊断观测了HL-2A极向截面的整个空间,15道观测弦以极向截面的中平面为轴对称分布,通过Abel反演得到了近红外轫致辐射信号的空间分布趋势。
In order to carry out the research on the physics related to the edge of Tokamak device and the more precise measurement of electron temperature and electron density by Thomson scattering, a near-infrared bremsstrahlung measurement system with high spatio-temporal resolution was initially established and measured in different Near infrared radiation under heating conditions. The feasibility of the system is verified by comparing with the bremsstrahlung signal of visible light and X-ray. The diagnosis observes the entire space of the polar cross section of HL-2A. The 15 observation chords are axisymmetrically distributed in the mid-plane of the polar section. The spatial distribution of near-infrared bremsstrahlung signals is obtained by Abel inversion.
