X-CT volume of a mineral inclusion within diamond Col-N-18 (10x objective)

Micron-scale X-CT of a mineral inclusion within a diamond. Comprised of breyite (CaSiO3) and perovskite (CaTiO3). Measurements were conducted at the I13 beamline of Diamond Light Source. 1800 projections were collected over a 180 degree rotation on a pco.edge 5.5 sCMOS Camera using a 10x objective lens (0.3 second exposures; 0.33 μm voxels).Diamond Col-N-18, from the Collier-4 kimberlite pipe, Brazil.

本数据集为金刚石内部矿物包裹体的微米级X射线计算机断层扫描（X-CT）数据。该包裹体由灰硅钙石（breyite，化学式CaSiO₃）与钙钛矿（perovskite，化学式CaTiO₃）组成。实验测试于钻石光源（Diamond Light Source）的I13光束线站开展。扫描过程中，采用10倍物镜镜头搭配pco.edge 5.5 sCMOS相机，在180度旋转范围内采集了1800幅投影图像，单幅曝光时长为0.3秒，扫描体素尺寸为0.33微米。该金刚石样品采自巴西Collier-4金伯利岩管，编号为Diamond Col-N-18。
