      abstract     = {This work presents the design, fabrication, and
                      experimental validation of a refractive diamond axicon for
                      X-ray beam shaping. The diamond axicon was developed to
                      overcome the limitations of polymer-based axicons
                      particularly for application in Transmission X-ray
                      Microscopy (TXM) systems, offering superior mechanical
                      strength, thermal stability, and radiation resistance,
                      making it ideal for synchrotron applications. The axicon was
                      fabricated using femtosecond laser ablation and tested at 11
                      keV under various coherence conditions. Results demonstrated
                      that the axicon efficiently transformed the X-ray beam into
                      a ring-shaped profile with over $80\%$ transmission.
                      Simulations confirmed the experimental findings and
                      highlighted the potential for further improvements. This
                      work paves the way for the use of diamond axicons in
                      next-generation synchrotron facilities, with future efforts
                      focusing on optimizing fabrication and testing the axicon in
                      full TXM systems.},
