However, accurately mapping the measured wavefront slope to a curved X-ray mirror surface when the modulator is downstream of the mirror has posed a challenge. To address this problem, an iterative method has been developed in this study. The results demonstrate a significant improvement compared ...

These in-situ and at-wavelength metrology methods can be used not only to optimize the performance of X-ray optics, but also to correct and minimize the collective distortions of upstream beamline optics, including monochromators, and transmission windows. An overview of at-wavelength metrology ...

X-rays are electromagnetic radiation that passes through solid objects. Learn the uses, dangers, results, side effects, and results of an x-ray scan.
Light is an electromagnetic wave with wavelengths between 0.1 nm and 100 μm. Visible light corresponds to wavelength in the range of 400–700 nm, vacuum ultraviolet light is in the range 0.1 μm to 10 nm; at the other end of the wavelength scale between 100 and 1000 μm is the microw...
Wavelength Dispersive X-ray Fluorescence (WDXRF) is one of two general types of X-ray Fluorescence instrumentation used for elemental analysis applications. In WDXRF spectrometers, all of the elements in the sample are excited simultaneously. The different energies of the characteristic radiation emitted...
formation of the signal is an indication that PS II was able to perform the charge separation reaction despite being exposed to the dithionite/benzyl viologen reduction protocol. The size of the EPR spectrum from Pheo− can be compared to the size (non-reduced) that amounts of to 1thread...
The first indication that SAD/MAD phasing might be feasible at an X-ray FEL was the detection of an anomalous signal for sulfur in a lysozyme data set collected by SFX16. Other preliminary successes with de novo structure determination at X-ray FELs have since been reported, including ...
摘要：PURPOSE:To give the modulation of a constant period to a spectral wavelength and to perform the experiments of X-ray diffraction, scattering, absorption by a phase sensitive detecting method with high accuracy, by adding a minute rotation vibrating apparatus to an X-ray spectral crystal. ...
