Observation of bio-fibres with a hard x-ray microscope

Hard X-Ray Microscope With Submicrometer Spatial Resolution

A high-resolution hard x-ray microscope is described. This system is capable of detecting line features as small as 0.6 µm in width, and resolving line pairs 1.2-µm wide and 1.2-µm apart. Three types of two-dimensional image detectors are discussed and compared for use with hard x rays in high resolution. Principles of x-ray image magnification are discussed based on x-ray optics and diffractio...

Development of a hard x-ray imaging microscope

A hard x-ray imaging microscope based on a phase zone plate has been developed and tested. The zone plate, with a 5 cm focal length and a 0.2 pm smallest linewidth, was used to image 8 keV x rays from the samples. The imaging microscope can be used to obtain nearly diffraction-limited resolution over the entire imaging field, and its resolution is almost independent of source size and source mo...

Observation of biological specimens using soft X-ray microscope

Biological specimens were observed using a soft X-ray microscope constructed at the Ritsumeikan synchrotron radiation center BL12. The spatial resolution of the microscope using an X-ray wavelength of 2.4nm was estimated to be 75nm from the edge response. Three kinds of diatoms were observed and ultrastructures of approximately 100nm could be clearly resolved. Two kinds of bacteria and red bloo...

Contrast with a 3D X-ray Microscope

A Hard X-ray KB-FZP Microscope for Tomography with Sub-100-nm Resolution

An instrument for high-resolution imaging and tomography has been built at the APS beamline 34 ID-C, Argonne National Laboratory. In-line phase contrast tomography can be performed with micrometer resolution. For imaging and tomography with resolution better than 100nm a hard X-ray microscope has been integrated to the instrument. It works with a Kirkpatrick-Baez (KB) mirror as condenser and a ...
