X-ray fluorescence analysis is a widely used technique in many applications. Recent advances in X-ray optics, in particular, in polycapillary manufacturing, have allowed achieving microscale spatial resolution, even with conventional sources. Nowadays, many apparatus for X-ray microfluorescence are available. But the majority of them are equipped with experimental chambers, which limit their applicability only to small-sized samples. To overcome this limitation, a newinstrument named Rainbow X-Ray (RXR), optimized for large and heavy objects, has been developed at XLab Frascati. Here, we present this unit dedicated to 2D and 3D X-ray microspectroscopy (both mapping and ‘colour‘ tomography), with a resolution between 25 and 75 m, depending from the incident energy in the range 800 eV–25 keV.

Abstract
X-ray fluorescence analysis is a widely used technique in many applications. Recent advances in X-ray optics, in particular, in polycapillary manufacturing, have allowed achieving microscale spatial resolution, even with conventional sources. Nowadays, many apparatus for X-ray microfluorescence are available. But the majority of them are equipped with experimental chambers, which limit their applicability only to small-sized samples. To overcome this limitation, a newinstrument named Rainbow X-Ray (RXR), optimized for large and heavy objects, has been developed at XLab Frascati. Here, we present this unit dedicated to 2D and 3D X-ray microspectroscopy (both mapping and ‘colour‘ tomography), with a resolution between 25 and 75 m, depending from the incident energy in the range 800 eV–25 keV.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
