同步辐射小角散射实验站探测系统的改进

Improvement of the Small Angle X-ray Scattering Station

同步辐射小角X射线散射 (SAXS)实验站所用的探测器由原来的NaI闪烁计数器改为位置灵敏探测器 ,其位置分辨好于 1 0 0 μm ,有效探测面积为 50mm× 1 0mm ,得到了较以往更高质量的SAXS谱 ,并成功地对液体样品的SAXS谱进行了测试 .

Instead of the NaI scintillation counter used before, a position sensitive detector was used with the position precision 100 μm and the effective working area 50 mm×10 mm. Good SAXS spectrum of liquid samples that can not be measured before was got. The statistical error was decreased and the total time of experiments was shortened.
