X-Ray Imaging Laboratory

The X-ray imaging laboratory is located in the E3 room of the experimental building, which is ideal for this kind of laboratory because of the lack of vibration, control of humidity and temperature, and radioprotection infrastructure. The main asset of this laboratory is a large radioprotection chamber (8600 mm x 6000 mm x 2200 mm) designed and equipped for high-sensitivity X-ray phase-contrast imaging experiments. The work of the team from this laboratory is dedicated to the development of X-ray diagnostics for laser-target interaction, biomedical X-ray imaging applications, industrial applications, fundamental science, and experiments for X-ray optics.

Topics

Phase-contrast imaging with X-ray sources produced by ELI-NP lasers for biomedical and industrial applications
Metrology for laser-based X-ray sources (source size, beam divergence, fluence, spectrum)
