  18. • Current maximum field of view 18 cm of diameter, should be increased to 25 cm (voxel size of 30 microns) before the end of the year on ID17. • Energy up to 180 keV in monochromatic on ID17 (suitable for rocks up to 25-30 cm • Energy up to 300 keV in polychromatic on ID19 (X-rays can go through about 40-45 cm of rock), but field of view limited to 10cm • Energy up to 200 keV in polychromatic on BM05, maximum field of view of 18 cm • In all the cases, propagation phase contrast is still usable due to high coherence of the beam and long propagation distances (up to 13 meters on ID19). • Industrial applications on metallic objects: maximum 8 cm of steel
