Diffraction of x-rays provides microscopic information of crystals such as symmetry, location of atoms within the unit cells etc. However, x-ray frequencies are high with respect to the characteristic energies of valence electrons (which are typically in UV range) and thus x-ray diffraction cannot be used to probe those electrons, which comprehensively determine chemical properties of atoms.
A novel system that enables the measurements of the effect of x-ray into ultraviolet down conversion with conventional, low-cost laboratory x-ray systems.
The Commercial Benefit
This cutting-edge system can be used for the measurements of spectroscopic and structural information on properties of valence electrons in a very broad range of frequencies with a single apparatus and without the requirements for high vacuum in contrast to most of other techniques in the field. The apparatus does not require external UV sources and provide a very broad range of frequencies fro the optical range to the soft x-ray regime.

Dr. Sharon Shwartz
• Dr. Shwartz is a physicist and Senior Lecturer in the Physics Department at Bar-Ilan University.
• Sharon is primarily interested in quantum optics, biphoton generation manipulation, the theory of nonlinear phenomena at x-ray energies as well as quantum optics in the x-ray regime.
• Dr. Shwartz received his PhD from the Technion – Israel Institute of Technology in 2008 under the supervision of Prof. Mordechai Segev. His thesis, “Nonlinear Optics in CZT:V”, researched new effects in a family of cubic nonlinear crystals. This led to the profound discovery that that under certain conditions of light illumination and applied electric fields; a class of material (cubic crystals with a low concentration of foreign atoms at energy level deep in the forbidden gap) becomes highly polar and greatly modifies its properties.
• After receiving his PhD, he spent four years as a postdoctoral fellow in Stanford University, hosted by Prof. Stephen E. Harris. He has been widely published in journals such as Applied Physics Letters, Physical Review Letters, Nature, Optics Letters, and Optics Express.
Develop the method of parametric down conversion into UV for spectroscopy in new materials and for the understanding of phenomena that requires the combination of the structure and spectral response of valence electrons in solid-state physics.
