Measurement Examples Using Polycapillary Parallel-beam Optics System

From Shimadzu Scientific Instruments, Inc.
 

 

The term "polycapillary" indicates multiple (poly) fine glass tubes (capillaries) that guide X-rays. Xrays generated by a point source are accepted at a high solid angle by the polycapillaries, and emerge as a parallel beam at the opposite end. This optics system utilizes the X-rays generated by the X-ray tube more efficiently than the standard (concentrating) method (the Bragg-Brentano Method), to achieve higher diffraction X-ray intensities. The parallel-beam polycapillary method used by the optics system ensures that the angle of diffraction does not change due to displacements of the sample measurement surface.
