The
current research activities utilize specific features
of full-field soft X-ray transmission microscopy
- elemental specificity of x-ray absorption
-
high
lateral resolution (currently down to 15nm)
provided by Fresnel zone plates as optical elements
-
large field of view of 15-20µm for a single
image, which can be tiled up to even larger images
-
recording images in varying external environments
(magnetic fields, temperatures)
-
sub-ns temporal resolution utilizing the pulsed
time structure of the storage ring in a stroboscopic
pump-probe scheme
- magnetic phase contrats
imaging
Therefore XM-1 is used to image at high spatial
and temporal resolution
microscopic structures with applications to magnetism,
materials and environmental
science and biology.
