The XLab Frascati (XlabF, Prof. S. Dabagov’s Lab) is specialized in theoretical and experimental research on interaction of various charged particles beams and electromagnetic radiation of a different frequency range between themselves and with the substance, also offering the possibility of conducting experiments with controlled analytical techniques on the use of X-rays (Tomography, Diffractometry and Fluorescence).
In parallel, the XlabF is focalised on the production and characterization of particular X-ray optics: the polycapillary lenses. These optics are made up of millions of hollow channels (capillaries) made of glass that offer the effective way for manipulation of X-rays, similarly to what happens with visible light in optical fibers, as in every single channel characterized by well-defined curvature the X radiation is transmitted through the multiple radiation reflection by internal capillary walls. The particular geometry of polycapillary lenses, with a characteristic “barrel” or “semi-barrel” shape, enables the collection of a divergent radiation beam to the optics focus or convert it into a quasiparallel beam. In this sense, the X-Channel Technological Pole (that’s part of XlabF) was established, with the aim of producing poly-and micro-capillaries to create X-ray optics of various shapes and transmission parameters. As a result, the use of polycapillary lenses with conventional X-ray sources enables the production of very brilliant sources of X-rays that, in turn, improve the performance of X-rays – based spectroscopies.
