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° .
