Testing the data framework for an AI algorithm in preparation for high data rate X-ray facilities
Hongwei Chen, Sathya R. Chitturi, Rajan Plumley +22
The advent of next-generation X-ray free electron lasers will be capable of delivering X-rays at a repetition rate approaching 1 MHz continuously. This will require the development…
Nanoscale heterogeneous dynamics probed by nanosecond x-ray speckle visibility spectroscopy
Yanwen Sun, Gabriella Carini, Matthieu Chollet +15
We report observations of nanosecond nanometer scale heterogeneous dynamics in a free flowing colloidal jet revealed by ultrafast x-ray speckle visibility spectroscopy. The nanosec…
Subterahertz collective dynamics of polar vortices
