摘要

通过改变与陶瓷有相似成份的GBW07306水系沉积物标准样品的前后位置和角度

研究了陶瓷样品外束质子荧光（External beam proton induced X-ray emission

外束PIXE）分析中样品位置对测量结果的影响。并以此为依据分析了陶瓷样品外束PIXE定量分析对样品定位精度的要求。结果表明:在质子能量为2.5MeV、样品距离质子引出窗口12mm和质子束入射方向夹角为30°、Si（Li）探测器在80°且距离样品20mm的实验条件下

沿束流方向位置变化引起的相对误差控制在5%以内时

样品定位精确度应高于±0.14mm;样品与质子束夹角变化引起的相对误差控制在5%以内时

样品角度定位需精确到±1.2°。

Abstract

The influence of sample position on analyzing Ar

Ca and Fe by external beam PIXE was studied by changing the position or direction of a GBW07306 sample. Precision requirements of sample–detector distance and incidence angle of the proton beam was determined. To control the PIXE analysis results with an accuracy of better than 5%

the displacement of sample position should be within ±0.14mm and the angle change within ±1.2° .
