A
capillary condenser produces focused X-rays for a full-field
illumination of the sample, projected onto the scintillator detector
using a Fresnel zone plate.
The two Zernike phase-contrast nano-CT scans of the cathode required 1200 X-ray radiograph projections per scan, with a 30 second exposure time per projection.
The
two nano-CT datasets were then reconstructed using commercial software
employing parallel-beam filtered back-projection algorithms
(‘Reconstructor Scout-and-Scan’, Carl Zeiss., CA, U.S.A.),producing an
isotropic voxel length of 63.1 nm.
The reconstructed
volumes were then stitched using Avizo Fire software (Avizo, Thermo
Fisher Scientific, Waltham, Massachusetts, U.S.A.) producing one nano-CT
tomogram (EIL-014.tif).
Collected using an 810 Ultra X-ray-CT instrument (Zeiss Xradia 810 Ultra, Carl Zeiss., CA, USA).
Accelerating tube voltage of 35 kVp that employs a rotating chromium anode.
Quasi-monochromatic beam with a characteristic emission peak of 5.4 keV (Cr-Kα).
In order to capture the full electrode thicknesses, two CT scans were conducted of the sample.
The raw radiographs can be made available upon request - please state 'EIL-011.tif' and 'EIL-012.tif'.
