Naturally fractured coal sample

D. Nicolas Espinoza
Intact coal cores: X-ray (100kV and 250µA) with a 0.1mm filter of Cu to reduce beam hardening effect, detector (5fps (frame per second) and average of 10 = exposure time per radiography of #2s), number of radiographies 1440 over 360°. Image: 1634x1634x4115 voxels, 16bit with a resolution (both voxel size and spot size) of 25µm. Device: Ultratom RXSolutions Operator: Nicolas Lenoir Facility Location: Laboratoire Navier
