Single-shot Flash Imaging Using a Compact Soft X-Ray Microscope
Abstract: The visualization of nanoscale dynamics in real-
space can significantly contribute to the
understanding of nanoscale processes and to
accelerate the development of new nanodevices.
Bright flashes of soft x-ray (SXR) light make it
possible to freeze nanoscale motion by acquiring
single-shot images with nanometer spatial
resolution. Compact SXR lasers operating in the
gain-saturated regime have opened the opportunity
to probe the dynamics of nanoscale phenomena
through single-shot full-field image acquisitions
on a table-top. This thesis discusses the use of a
compact SXR microscope operating at wavelength of
46.9 nm in the visualization of a magnetic
nanoprobe perturbed motion by stray magnetic
fields. This demonstrations comprises the first
recording in real-space of movies of nanoscale
dynamic interactions.
