Research   Development

XGLab’s main priority is providing the most advanced technology in its field. Research is carried out by the Group of Nuclear Electronics of the Politecnico di Milano, with whom XGLab maintains a very close working relationship.
This opportunity for comparison, combined with the synergies that are constantly being created between the two work teams, has allowed the company to enter into major international collaborations with leading multinational companies.

ELEMENTAL MAPPING APPLICATIONS


XGLab’s Research Team works to develop measurement systems for elemental analysis based on XRF spectroscopy, in particular for elemental mapping applications, the identification of the chemical elements present in a sample and the determination of their spatial distribution. The FELIX (Fast Elemental Imaging with X-ray) spectrometer, for example, was carried out at Politecnico di Milano, funded by INFN (the Italian Institute for Nuclear Physics).

A ring-shaped detector made of a monolithic array of four SDD of the novel “droplet” type is the core of the FELIX spectrometer. The total active area of the four element detector is about 60 mm2 and can be reduced to about 50 mm2 by screening the anode and transistor regions to optimize spectrometer performance. The four detectors surround the central hole; the hole laser-cut in the center of the ring lets the excitation beam reach the sample. A micro-focus X-ray generator coupled to a polycapillary X-ray lens focuses the primary beam on the sample through the hole laser-cut in the center of the detector chip.

The polycapillary lens concentrates a high photon flux on a small spot on the sample, with a diameter of a few tens of micrometers, which guarantees high spatial resolution. The detector-sample geometry allows the collection of a large fraction of the emitted fluorescence. Moreover, the distance between the sample and the detector can be reduced with a corresponding reduction of air absorption on the fluorescence radiation coming from light elements.

These features, together with the high detection rate of the SDDs, shortens the scanning time in elemental mapping since operation at several tens of kcps with no energy resolution degradation is possible. To achieve mapping capability with XRF, usually, the sample is placed on an XY motion stage and its surface is scanned over a matrix of points by moving the sample itself.
