查询词典 gamma ray

X-ray ,which is excited from the X ray tube, has one wavelength scope, that is energy scope. According to the elements to be analyzed, X ray is choused by filter, and reach the sample. Atoms in the sample will absorb the X ray energy and the decay to emit the special x ray. The X ray will be collected by the collimator into the detector active area, and transferred into electron signal, the signal also will be processed in to energy spectrum and related concentration data by pulse processor with software.

从X光管通过激发Excitation发射出来一定波长范围也就是说一定能量范围的X射线，结合所需要分析的目标元素，使用滤光轮选择对应的能量范围的X射线，照射到样品上，样品中含有的元素原子电子受到激发会发射出其特征的X射线，同样通过Collimator准直器收集一定孔径的X射线进入到检测器Detector，检测器将感应到的X射线转换为电信号，电信号经过脉冲处理器Pulse Processor结合软件进一步将电信号转换成为能谱图以及相关浓度信息。
