Three-dimensional coherent diffractive imaging on non-periodic specimens at the ESRF beamline ID10

Area of Science:

• Materials Science
• Physics
• Imaging Science

Background:

• Advancements in X-ray imaging techniques are crucial for characterizing nanoscale materials.
• Tomographic coherent diffractive imaging (TCDI) offers high-resolution 3D structural information.
• Hard X-rays provide greater penetration depth for imaging denser or thicker samples.

Purpose of the Study:

• To present the progress of TCDI using hard X-rays at the European Synchrotron Radiation Facility (ESRF) ID10 beamline.
• To demonstrate the instrument's performance in achieving high-resolution 3D imaging.
• To showcase the capability of imaging non-crystalline samples in ambient conditions.

Main Methods:

• Utilized hard X-rays at 8 keV photon energy for diffraction measurements.
• Employed TCDI techniques to reconstruct the 3D structure from diffraction data.
• Phased a measured diffraction volume to obtain the sample's electron density distribution.

Main Results:

• Achieved a 3D resolution of 59 nm for imaging a cluster of Fe2P magnetic nanorods.
• Successfully reconstructed the 3D morphology and structure of the magnetic nanorods.
• Demonstrated the feasibility of TCDI for non-crystalline samples in air.

Conclusions:

• The ID10 beamline at ESRF shows significant progress in hard X-ray TCDI.
• High-resolution 3D imaging of magnetic nanostructures is achievable with this technique.
• This method advances the 3D characterization of non-crystalline materials in ambient environments.
