Geometrical Effects on the XRF Spectrometer Data Validity Using Hypothetical 20 keV Photon Source

Abstract

The factors associated with source – sample – detector geometry and radiation absorption by 2 cm in diameter circular carbon samples on the x-ray fluorescence spectrometer data validity is studied. Radiation coming out from various parts of the sample may not share in equal manner to the detector signal if the geometry is not calculated correctly. This case may also arise if a sample is not homogeneous, so if correct geometry is designed the decision on sample homogeneity can be made. Carbon samples of 30 mg/cm2 are supposed and suitable distance from 20 keV hypothetical photon source and detector were found in a search to solve the geometry problem.
