X-ray Diffraction Data Collection
نویسنده
چکیده
“point” and “area” (originally film) detectors. The first X-ray diffraction experiment by Friedrich and Knipping [1] used film, but within the same year Bragg was using an ionization chamber mounted on a rotating arm [2]. The advantage of Bragg's X-ray detector was that it defined precisely the angle of the diffracted rays and, in general, gave more accurate intensity measurements. The advantage of film was that it readily recorded many reflections on one exposure. However, counter devices were tedious to use, particularly without automatic motorized drives, while film devices gave poor positional and intensity estimates.

A multi-dataset data-collection strategy produces better diffraction data
A multi-dataset (MDS) data-collection strategy is proposed and analyzed for macromolecular crystal diffraction data acquisition. The theoretical analysis indicated that the MDS strategy can reduce the standard deviation (background noise) of diffraction data compared with the commonly used single-dataset strategy for a fixed X-ray dose. In order to validate the hypothesis experimentally, a data...
متن کاملA high-transparency, micro-patternable chip for X-ray diffraction analysis of microcrystals under native growth conditions
Microcrystals present a significant impediment to the determination of macromolecular structures by X-ray diffraction methods. Although microfocus synchrotron beamlines and X-ray free-electron lasers (XFELs) can enable the collection of interpretable diffraction data from microcrystals, there is a need for efficient methods of harvesting small volumes (<2 µl) of microcrystals grown under common...
متن کاملA new approach to synchrotron energy-dispersive X-ray diffraction computed tomography.
A new data collection strategy for performing synchrotron energy-dispersive X-ray diffraction computed tomography has been devised. This method is analogous to angle-dispersive X-ray diffraction whose diffraction signal originates from a line formed by intersection of the incident X-ray beam and the sample. Energy resolution is preserved by using a collimator which defines a small sampling voxe...
متن کاملA Medipix quantum area detector allows rotation electron diffraction data collection from submicrometre three-dimensional protein crystals
When protein crystals are submicrometre-sized, X-ray radiation damage precludes conventional diffraction data collection. For crystals that are of the order of 100 nm in size, at best only single-shot diffraction patterns can be collected and rotation data collection has not been possible, irrespective of the diffraction technique used. Here, it is shown that at a very low electron dose (at mos...
متن کاملCombining X-ray crystallography and single-crystal spectroscopy to probe enzyme mechanisms.
The combination of X-ray crystallography and rapid cryo-trapping methods has enabled the visualization of catalytic intermediates in a variety of enzyme systems. However, the resolution of the X-ray experiment is not always sufficient to precisely place the structure on the reaction pathway. In addition, many trapped intermediates are X-ray-sensitive and can decay during diffraction data collec...
متن کاملThe finer things in X-ray diffraction data collection.
X-ray diffraction images from two-dimensional position-sensitive detectors can be characterized as thick or thin, depending on whether the rotation-angle increment per image is greater than or less than the crystal mosaicity, respectively. The expectations and consequences of the processing of thick and thin images in terms of spatial overlap, saturated pixels, X-ray background and I/sigma(I) a...
