为了提高X射线荧光（XRF）扫描分析的性能，对俄罗斯新西伯利亚布克尔核物理研究所VEPP-3储存环上的XRF光束线进行了改进。利用扫描同步辐射X射线荧光（SR-XRF）分析技术研究了捷列茨基湖沉积物柱样中碱金属和微量元素的分布特征。元素浓度的变化与气候参数相关。扫描分析的空间分辨率为1 mm，对应于0.1年的时间分辨率。重建了1200年以前的年气温和降水量时间序列。
The X-ray Fluorescence (XRF) beamline at the VEPP-3 (Budker Institute of Nuclear Physics, Novosibirsk, Russia) storage ring was modified for the performance of scanning analysis. Scanning Synchrotron Radiation X-ray Fluorescence (SR-XRF) analysis was used for studying of the base and trace elements distributions in cores of bottom sediments from Teletskoe Lake. The variations in elements concentration are correlated with climate parameters. A spatial resolution of the scanning analysis is 1mm which corresponds to ∼1 years of time resolution. The time series for annual temperature and precipitation until 1200 AD were reconstructed.
