Design of a Beam Size Monitor Using Fresnel Zone Plates
Measuring electron-beam sizes is very important to estimate horizontal and vertical emittances in lowemittance rings. The beam size monitor using Fresnel zone plates (FZPs) has been designed for the Super-SOR ring (a new name of the VSX ring), which is a thirdgeneration synchrotron light source being planned by the University of Tokyo. The monitor system has a structure of a long-distance x-ray...
متن کاملHigh-resolution differential interference contrast X-ray zone plates: Design and fabrication
Differential interference contrast is a potentially powerful technique for contrast enhancement in soft X-ray microscopy. We describe the design and fabrication of single-element diffractive optical elements suitable as objectives for high-resolution differential interference contrast microscopy in the water-window spectral range. A one-dimensional pattern calculation followed by an extension t...
متن کاملAn Integrated Sequence Construction of Binary Zero-Correlation Zone Sequences
The present paper introduces an integrated construction of binary sequences having a zero-correlation zone. The cross-correlation function and the side-lobe of the auto-correlation function of the proposed sequence set is zero for the phase shifts within the zero-correlation zone. The proposed method enables more flexible design of the binary zerocorrelation zone sequence set with respect to it...
متن کاملHigh-Aspect Ratio Nanofabrication for Hard X-Ray Zone Plates
Hard x-ray nanoimaging enables structural investigations of newmaterials for many applications. For high-resolution experiments, zone plate x-ray optics are commonly chosen. Two methods of zone plate nanofabrication are presented in this thesis. Zone plates are circular diffraction gratings with radially decreasing grating period. Their optical resolution depends on the width of the smallest zo...
متن کاملZone-doubled Fresnel zone plates for high-resolution hard X-ray full-field transmission microscopy
Full-field transmission X-ray microscopy is a unique non-destructive technique for three-dimensional imaging of specimens at the nanometer scale. Here, the use of zone-doubled Fresnel zone plates to achieve a spatial resolution better than 20 nm in the hard X-ray regime (8-10 keV) is reported. By obtaining a tomographic reconstruction of a Ni/YSZ solid-oxide fuel cell, the feasibility of perfor...
