X-Ray Absorption spectroscopy (XAS) - and in particular Extended X-ray Absorption Fine Structure (EXAFS) - are powerful synchrotron techniques used to characterize materials, which can give information on the present

atomic species, their oxidation state and their electronic configuration. However, performing XAS experiments outside synchrotron facilities has been always extremely challenging due to the much lower brilliance. Thanks to the technology development of the new available compact lab X-ray sources, we aim to overcome this limitation. Within the frame of the NeXT-GAME and PNRR MUSA projects, we have designed in collaboration with Cinel.srl (a top-level company in the field of x-ray and vacuum technology) a new table-top XAS spectrometer to be installed at PoliMi, and to be used jointly with the Chemistry Department for studies on new materials, next generation batteries, catalysis and biochemistry.

The candidate master degree student, followed by the Polimix group staff, will contribute to the commissioning of the instrument and to the first measurements. Part of the work will consist in the writing of the control software. This internship is thought to be highly hands-on and it represents a rare opportunity to gain valuable skills in x-ray optics and vacuum technology. Starting date as soon as possible.
