Description

X-ray ptychographic tomography is now routinely used at synchrotron facilities around the world, producing nanoscale resolutions in 3D. However, the acquisition times still lag significantly behind other imaging methods. As many synchrotrons upgrade to diffraction limited rings, the community is being presented with a dramatic increase in the coherent flux available. There have many developments in recent years, from multibeam illuminations to fly scanning trajectories. However, translating the increase in flux into increased scientific throughput remains a challenge. The latest advances in high-speed ptychography at I13-1: Coherence of the Diamond Light Source have combined a novel acquisition scheme with the SELUN detector from DECTRIS, which is capable of 120kHz in continuum mode, to achieve ptychography collection rates of over 100 kHz. This is providing sub-second projections and sub-hour 3D ptychographic tomography. We present the latest technical developments as well as their applications in the fields of battery materials and brain imaging.
