3D diffractive imaging of nanoparticle ensembles using an X-ray laser
Kartik Ayyer, P. Lourdu Xavier, Johan Bielecki +34
We report the 3D structure determination of gold nanoparticles (AuNPs) by X-ray single particle imaging (SPI). Around 10 million diffraction patterns from gold nanoparticles were m…
speckle-tracking: a Software Suite for Ptychographic X-ray Speckle Tracking
Andrew J. Morgan, Kevin T. Murray, Harry M. Quiney +2
In recent years, x-ray speckle tracking techniques have emerged as viable tools for wavefront metrology and sample imaging applications. These methods are based on the measurement…
Ptychographic X-ray Speckle Tracking with Multi Layer Laue Lens Systems
Andrew James Morgan, Kevin T. Murray, Mauro Prasciolu +19
The ever-increasing brightness of synchrotron radiation sources demands improved x-ray optics to utilise their capability for imaging and probing biological cells, nano-devices, an…
Ptychographic X-ray Speckle Tracking
Andrew J. Morgan, Harry M. Quiney, Saša Bajt +1
We present a method for the measurement of the phase gradient of a wavefront by tracking the relative motion of speckles in projection holograms as a sample is scanned across the w…
X-ray diffractive imaging of controlled gas-phase molecules: Toward imaging of dynamics in the molecular frame
Thomas Kierspel, Andrew Morgan, Joss Wiese +25
We report experimental results on the diffractive imaging of three-dimensionally aligned 2,5-diiodothiophene molecules. The molecules were aligned by chirped near-infrared laser pu…
Continuous Diffraction of Molecules and Disordered Molecular Crystals
Henry N. Chapman, Oleksandr M. Yefanov, Kartik Ayyer +6
The diffraction pattern of a single non-periodic compact object, such as a molecule, is continuous and is proportional to the square modulus of the Fourier transform of that object…
