X-ray imaging is needed to diagnose inertial confinement fusion (ICF) implosions. For example, radiography using an x-ray backlighter target allows the size, symmetry, and density of both the compressed core and surrounding shell to be determined. One means of imaging ICF target x-ray emission is a compact Kirkpatrick-Baez (KB) microscope. Before a KB microscope is used, the KB optic must have ...

X-ray microtomography has been developed for use in various fields such as biology, materials science, petrology, and medical diagnosis. This method’s setup commonly consists of a simple projection geometry with a high-resolution imaging detector and a highly collimated beam, e .g . , a microfocussing X-ray tube or synchrotron radiation source, which can result in a spatial resolution of about ...

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...

in this paper, nano fibers (engelhard corporation titanosilicate number 10 / polyacrylonitrile) ets-10 / pan, as a composite exchanger to absorb heavy metals, were synthesized and optimized. several parameters were affected on this absorption. results show that the optimization sizes of the nano fibers are about 75 nanometers. structures were analyzed by scanning electron microscope (sem) and e...

Using X-ray microscopy and spectromicroscopy, vascular smooth muscle cells (VSMCs) were imaged, prepared without using additional embedding material or staining, but by applying simple, noncryo fixation techniques. The cells were imaged with a compact source transmission X-ray microscope and a scanning transmission X-ray microscope (STXM). With the STXM, spectromicroscopy was performed at the C...

In this paper the choice between bending magnets and insertion devices as sample illuminators for a hard X-ray full-field microscope is investigated. An optimized bending-magnet beamline design is presented. Its imaging speed is very competitive with the performance of similar microscopes installed currently at insertion-device beamlines. The fact that imaging X-ray microscopes can accept a lar...

cadmium oxide (cdo) nanoparticles were prepared by precipitation method using cadmium acetate and ammonia solution. presence of chemical species, were verified by fourier transform infra red (ftir) spectrum. from x-ray diffraction (xrd) spectrum the particle size, d-spacing value and structure of the nanoparticle were analysed. size of the nanoparticles and the elemental composition were detect...

We obtain quantitative phase reconstructions from differential phase contrast images obtained with a scanning transmission x-ray microscope and 2.5 keV x rays. The theoretical basis of the technique is presented along with measurements and their interpretation.
