A Biological X-ray Microscopy Resource Center is planned to be built at the Advanced Light Source (ALS) in Berkeley. The first instrument will be the High Resolution Zone Plate Microscope (XM-1) installed at the bending magnet beam line 6.12. It will be operational in August 1994. The optical setup of this x-ray microscope is analog to a conventional visible light microscope using critical illumination (Fig. 1). Fresnel zone plates are used for both condenser and high resolution objective. The condenser zone plate illuminates the sample, and at the same time, in combination with a pinhole, acts as a monochromator providing quasi monochromatic illumination. The high resolution objective zone plate is used to create an enlarged image of the sample on a back-illuminated CCD detector. Exposure times for images with 1000 by 1000 pixels are expected to be a few seconds. In order to permit examination of the sample before and after the x-ray imaging, the design of our instrument includes two visiblelight microscopes.

AbstractTo diagnose the implosion of a laser-driven-fusion target such as the symmetry, the hydrodynamic instability at the interface, a high-resolution, large field-of-view kilo-electron-volt X-ray imaging is required. A Kirkpatrick-Baez (K-B) microscope is commonly used, but its field of view is limited to a few hundred microns as the resolution decreases rapidly with the increase of the field of view. A higher resolution could be realized by using a Fresnel zone plate (FZP) for imaging. Presented in this work is a numerical study on the imaging properties of an FZP at Ti-Kα wavelength of 0.275 nm, and a comparison to a K-B imager. It is found that the FZP can realize not only a resolution better than 1 µm, but also a field-of-view larger than 20 mm when the FZP is illuminated by X-rays of spectral bandwidth less than 1.75%. These results indicate the feasibility of applying the FZP in high-resolution, large field-of-view X-ray imaging.

The effect of scintillator particle size on high-resolution X-ray imaging was studied using zinc tungstate (ZnWO4) particles. The ZnWO4 particles were fabricated through a solid-state reaction between zinc oxide and tungsten oxide at various temperatures, producing particles with average sizes of 176.4 nm, 626.7 nm, and 2.127 μm; the zinc oxide and tungsten oxide were created using anodization. The spatial resolutions of high-resolution X-ray images, obtained from utilizing the fabricated particles, were determined: particles with the average size of 176.4 nm produced the highest spatial resolution. The results demonstrate that high spatial resolution can be obtained from ZnWO4 nanoparticle scintillators that minimize optical diffusion by having a particle size that is smaller than the emission wavelength.
