High‐flux, moderate‐bandwidth, high‐energy X‐rays from lapped Si(111) crystals in a double‐crystal monochromator

Journal of Synchrotron Radiation, EarlyView.
Lapped Si(111) crystals in a double‐crystal monochromator provide high‐flux, spectrally pure, and moderate‐bandwidth X‐ray beams at 100 keV, offering a robust and cost‐effective alternative to perfect‐crystal and multilayer optics.Lapping the surfaces of Si(111) crystals in a double‐crystal monochromator significantly increases the intensity of high ...

Wavefront Sensor and Method of Reconstructing Distorted Wavefronts

, 2016
A wavefront sensor includes a mask and a sensor utilized to capture a diffraction pattern generated by light incident to the mask. A reference image is captured in response to a plane wavefront incident on the mask, and another measurement image is ...

Diffractive wavefront correction for Fe L‐edge spectroscopy on the meV scale

Journal of Synchrotron Radiation, EarlyView.
We propose an aberration‐corrected, wavelength‐dispersive instrument for soft X‐ray spectroscopy at an energy‐resolving power of (5–6) × 104, designed for, for example, resonant inelastic X‐ray scattering at synchrotron beamlines or X‐ray free‐electron lasers.We propose a wavelength‐dispersive instrument for high‐resolution soft X‐ray spectroscopy at ...

Patient‐reported outcomes and visual function after four refractive strategies in cataract surgery: A randomized controlled trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate patient‐reported outcome measures (PROMs) and visual function across four groups of public cataract patients: emmetropia, mini‐monovision, monovision with partial‐range of field (RoF) narrow intraocular lenses (IOLs) and patients implanted with partial‐RoF extended IOLs.
