Full-field transmission x-ray microscopy at SSRL

A full-field hard-x-ray microscope at SSRL with 15 micron field of view and 40 nm resolution, as well as 3D tomographic capabilities, has successfully imaged samples of biological, environmental and astronomical origin. Spectroscopic imaging of a particle of comet dust from the NASA Stardust mission showed significantly more absorption contrast above the Fe K-edge, and tomography revealed the t...

Polarization-modulated magnetic soft-x-ray transmission microscopy

An adjustable aperture element has been integrated into the full-field soft-x-ray microscope at the Advanced Light Source to select either the right or left elliptically polarized x rays emitted at an inclined angle from a bending magnet. Magnetic contrast recorded at the Fe L3 edge in a 59-nm-thin Gd25Fe75 layer can be modulated and scales with the degree of circular polarization in agreement ...

High numerical aperture tabletop soft x-ray diffraction microscopy with 70-nm resolution.

Light microscopy has greatly advanced our understanding of nature. The achievable resolution, however, is limited by optical wavelengths to approximately 200 nm. By using imaging and labeling technologies, resolutions beyond the diffraction limit can be achieved for specialized specimens with techniques such as near-field scanning optical microscopy, stimulated emission depletion microscopy, an...

Direct time resolved observation of molecular dynamics induced by soft-x-ray photoionization

We report the first direct observation of ultrafast dynamics in molecules induced by ionizing radiation. We use high harmonic upconversion process to generate soft-x-ray pulses of few femtoseconds duration, which photoionize N2 molecule. This leads to the formation of highly excited N2 ions via inner-shell ionization and electron shakeup processes. We time resolve the unexplored fragmentation d...
