Laboratory-size X-ray Microscope using Wolter Mirror Optics and an Electron-impact X-ray Source for Multi-energy Observation

X-ray microanalysis attachment for electron microscope.

An X-ray polarimeter for hard X-ray optics

Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays. We calculated the sensitivity with Neon and Argon based mixtures at high pressure with thick absorption gap: placing the MPGC at focus of a next generation multi-layer ...

Image quality improvement in a hard X-ray projection microscope using total reflection mirror optics.

A new figure correction method has been applied in order to fabricate an elliptical mirror to realize a one-dimensionally diverging X-ray beam having high image quality. Mutual relations between figure errors and intensity uniformities of diverging X-ray beams have also been investigated using a wave-optical simulator and indicate that figure errors in relatively short spatial wavelength ranges...

An x-ray photoemission electron microscope using an electron mirror aberration corrector for the study of complex materials

A new ultrahigh-resolution photoemission electron microscope called PEEM3 is being developed at the advanced light source (ALS). An electron mirror combined with a sophisticated magnetic beam separator is used to provide simultaneous correction of spherical and chromatic aberrations. Installed on an elliptically polarized undulator beamline, PEEM3 will be operated with very high spatial resolut...

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...
