There should be no damage but you may see a slit change in color where the beam hits the sample, a temporary change in the color center. I suggest running your generator at 45 kV and 35 mA you will get more intensity. Cheers, Ed On Sun, May 21, 2017 at 12:21 PM, Shay Tirosh

You can run into “interesting” behavior with metastable phases. I once ran a sample that gradually transformed from the “high temperature” structure to the “low temperature” under x-ray illumination. The two phases were red and yellow, so it was very obvious where the x-ray beam had illuminated
