Abstract

A focusing optics that can provide a sub‐micrometre high‐flux probe for soft X‐ray micrometre‐scale angle‐resolved photoemission spectroscopy (ARPES) is proposed. A monolithic Wolter‐type mirror with a large acceptance, achromatism and small comatic aberration was designed and evaluated. A focused beam size of 0.4 µm (vertical) × 4 µm (horizontal), a high throughput of 59% and a high tolerance of 1.6 mrad to the pitching error were realized at a photon energy of 1000 eV. A Wolter‐type mirror can be practically employed as a stable sub‐micrometre focusing mirror with high throughput in ARPES applications. [ABSTRACT FROM AUTHOR]

Abstract

We developed a soft X-ray microscopic imaging system, CARROT, that combines ptychography and fluorescence X-ray microscopy using a total-reflection Wolter mirror illumination system. The system offers advantages such as achromaticity and long working distances, enabling seamless application to a wide wavelength range. We demonstrated high-resolution imaging of cellular structures and sub-micrometer-scale changes induced by drug administration in mammalian cells. We further showcased the capability to seamlessly switch from ptychography measurements to X-ray fluorescence measurements at different wavelengths to map elemental distributions within cells. Our findings suggest that this system can be used for investigating the correlation between intracellular structures and elemental distribution, as well as for multimodal measurements of visible light fluorescence, Raman scattering, and soft X-rays to provide valuable insights into understanding intracellular dynamics. • New imaging system combines soft X-ray ptychography & fluorescence microscopy. • High-resolution images of drug-treated mammalian cells reveal sub-micrometer changes. • Investigation of the correlation between intracellular structures and elemental distribution.

Abstract

An axisymmetric multi-mirror system for neutron and X-ray microscopes is proposed to increase their numerical aperture and collection efficiency. A Wolter type-I mirror is used as the basis of the multi-mirror system at grazing incidence. The addition of an even number of hyperboloid mirrors to the Wolter type-I mirror can satisfy both an equal optical path length and Abbe's sine condition. The numerical aperture increases in proportion to the number of mirrors. The optical parameters of the system with four tandem mirrors are calculated for neutrons and X-rays with a wavelength of 0.4 nm by assuming that the average grazing angle of incidence is 5.4 mrad and the magnification is 10. The inner diameters of the mirrors are limited to <10 mm considering the total length of the optical system. Tolerance of off-axis distance was calculated using a ray-tracing computer simulation. Ray tracing shows that a blur size <14 nm will be possible at an off-axis displacement of 10 μm. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: A high-resolution soft X-ray emission spectrometer has been developed for site-specific electronic structure analysis of functional materials in the photon energy range of 50–600eV on the in-vacuum undulator beamline BL3U of the UVSOR facility. In order to realize the high detection efficiency without sacrificing the energy resolution to the signal intensity, the present X-ray emission spectrometer adopts an optical design, which was originally adopted in the field of astrophysics such as Chandra X-ray observatory. This new-type X-ray emission spectrometer consists of a Wolter type I mirror, a freestanding transmission grating, and a charge coupled device (CCD) detector, allowing the focusing with 20 times larger acceptance angle (1.5×10−3 sr) than commercially available compact spectrometers with reflection-type gratings such as VG-SCIENTA XES350. The X-ray emission energy resolution of 15–34meV has successfully been achieved in the photon energy of 60–100eV by using a transmission grating with the groove density of 5555lines/mm.

Abstract

An ultra-precision ELID grinding of large stamping dies of Wolter mirror for X-ray telescope was presented in this paper. The large stamping dies (S55C) with confocal paraboloid and hyperboloid was ground by ELID arc-enveloped grinding. In this ELID grinding system, cast iron fiber bonded (CIFB) diamond wheels were controlled by 3-dimentional ways to scan the work-piece and generate required surfaces. Its grinding characteristics such as attainable form accuracy, surface roughness were investigated. Furthermore, some measures to improve form accuracy were discussed and verified such as truing, compensating, and on-machine measuring. [ABSTRACT FROM AUTHOR]

Abstract

High resolution imagery of the solar X-ray corona provides a crucial key to understand dynamics and heating processes of plasma particles there. However, X-ray imagery of the Sun with sub-arcsecond resolution has yet to be conducted due to severe technical difficulty in fabricating precision Wolter mirrors. For future X-ray observations of the Sun's corona, we are attempting to realize precision Wolter mirrors with sub-arcsecond resolution by adopting advanced surface polish and metrology methods based on nano-technology to sector mirrors which consist of a portion of an entire annulus. Following fabrication of the first engineering mirror and subsequent evaluation on the X-ray focusing performance in 2013, the second engineering mirror was made with improvements in both precision polish and metrology introduced. Measurement of focusing performance on the second mirror at SPring-8 synchrotron facility with 8 keV X-rays has demonstrated that the FWHM size of the PSF core reached down to 0.2" while its HPD (Half Power Diameter) size remained at ~3" due to the presence of small-angle scatter just outside of the core. Also, there was notable difference in the focal length between sagittal and meridional focusing which could have been caused by an error in the sag in the meridional direction of

An achromatic and high-resolution hard X-ray microscope was developed, in which advanced Kirkpatrick-Baez mirror optics with four total-reflection mirrors was employed as an objective. A fine test pattern with a 100 nm feature size could successfully be resolved. Full-field imaging, in combination with X-ray absorption near edge structure (XANES) spectroscopy, was used to characterize tungsten particles. XANES spectra were obtained over the entire observation area, showing good agreement with the XANES spectrum of pure tungsten.

Compact advanced Kirkpatrick–Baez optics are used to construct a microscope that is easy to align and robust against vibrations and thermal drifts. The entire length of the imaging mirror system is 286 mm, which is 34% shorter than the previous model. A spatial resolution test is performed in which magnified bright-field images of a pattern are taken with an X-ray camera at an energy of 10 keV at the BL29XUL beamline of SPring-8. A line-and-space pattern having a 50- nm width could be resolved, although the image contrast is low.

S. Matsuyama, N. Kidani, H. Mimura, J. Kim, Y. Sano, K. Tamasaku, Y. Kohmura, M. Yabashi, T. Ishikawa, and K. Yamauchi "Development of a one-dimensional Wolter mirror for achromatic full-field x-ray microscopy", Proc. SPIE 8139, Advances in X-Ray/EUV Optics and Components VI, 813905 (28 September 2011); https://doi.org/10.1117/12.892987., SPIE Optical Engineering + Applications, 2011, San Diego, California, United States, We investigated a one-dimensional Wolter mirror (which consists of an elliptical mirror and a hyperbolic mirror) with the aim of developing an achromatic full-field X-ray microscope with a resolution of better than 50 nm. X-ray mirrors were ultraprecisely fabricated by elastic emission machining to give a figure accuracy of 2 nm (peak-to-valley). A one-dimensional Wolter mirror that had been precisely constructed was evaluated in terms of the point-spread function at the center of the field of view (FOV) and the FOV at an X-ray energy of 11.5 keV at BL29XUL of SPring-8. It was found to have a minimum resolution of 43 nm and a FOV equivalent to 12.1 μm. These results are highly consistent with calculation results. © 2011 SPIE.

The figure accuracies of the elliptical and hyperbolic mirrors required to obtain diffraction-limited resolution were investigated using a wave-optical simulator, and then elliptical and hyperbolic mirrors were precisely fabricated, following the criterion of the figure accuracies. Experiments to form a demagnified image of a one-dimensional slit installed 45 m upstream were conducted using the imaging system at an X-ray energy of 11.5 keV at BL29XUL of SPring-8. The system could form a demagnified image with the best resolution of 78 nm. In addition, the field of view to obtain a resolution better than 200 nm was 4.2 micron. © 2010 SPIE.
