 \n\nVOXES is a high-resolution X-ray spectrometer developed at the INFN La
 boratori Nazionali di Frascati for X-ray spectroscopy measurements in the 
 5 to 50 keV energy range\, with applications to both X-ray fluorescence an
 d absorption studies.\nBased on the Von Hamos geometry\, the setup is desi
 gned to provide a few-eV energy resolution (FWHM)\, depending on the adopt
 ed crystal\, detector\, and measurement conditions.\nOne of the distinctiv
 e features of VOXES is its capability to perform high-resolution measureme
 nts also on extended sources\, enabled by the combined use of crystal disp
 ersion and slit-based source shaping.\nIn this talk\, after introducing th
 e main characteristics of the spectrometer\, I will show how these feature
 s make VOXES a flexible platform for a broad range of applications. The se
 tup includes mosaic and germanium crystals\, strip\, CCD\, and pixel detec
 tors\, and X-ray tubes with Mo and W anodes operating up to 80 kV and curr
 ents of the order of mA. The system is installed in a dedicated shielded b
 unker\, suitable for experimental integration and further developments. Th
 e spectrometer is fully motorized for alignment procedures and complemente
 d by auxiliary diagnostics\, including a pin diode for monitoring\, ensuri
 ng operational flexibility and reproducibility.\nOn this basis\, I will di
 scuss selected application areas that illustrate the scientific and techno
 logical relevance of VOXES for LNF activities. These include measurements 
 on liquid samples for edible-liquid analysis within the MITIQO project\, m
 easurements on perovskite detectors\, imaging with the GEM detector\, and 
 ongoing activities in collaboration with ENEA on battery-related materials
 .\nPossible future developments will also be outlined in connection with E
 uPRAXIA and EuAPS\, where compact high-resolution X-ray spectroscopy may p
 rovide useful support for diagnostics and materials characterization. In t
 his perspective\, VOXES represents an experimental infrastructure with the
  potential to contribute to the strengthening of laboratory capabilities a
 nd to support interdisciplinary activities within LNF and beyond.\n\nhttps
