Schematic of the depth-resolved Bragg CDI approach. Before the measurements, the axis of rotation of the instrument (ω) is aligned to intersect with the focused X-ray beam. The sample (in our case, a battery cathode in a coin cell) is searched for particles that have bright and isolated Bragg peaks on the 2D detector. We use the right-hand coordinate system with the z axis along the direction of the X-ray beam and the y axis aligned with the sample rotation axis. |
