Data collection strategies for time-resolved X-ray free-electron laser diffraction, and 2-color methods
We compare three schemes for time-resolved X-ray diffraction from protein nanocrystals using an X-ray free-electron laser. We find expressions for the errors in structure factor measurement using the Monte Carlo pump-probe method of data analysis with a liquid jet, the fixed sample pump-probe (goniometer) method (both diffract-and-destroy, and below the safe damage dose), and a proposed two-col...
متن کاملThe collection of high-resolution electron diffraction data.
A number of atomic-resolution structures of membrane proteins (better than 3Å resolution) have been determined recently by electron crystallography. While this technique was established more than 40 years ago, it is still in its infancy with regard to the two-dimensional (2D) crystallization, data collection, data analysis, and protein structure determination. In terms of data collection, elect...

“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 advantag...
متن کاملThree-dimensional rotation electron diffraction: software RED for automated data collection and data processing
Implementation of a computer program package for automated collection and processing of rotation electron diffraction (RED) data is described. The software package contains two computer programs: RED data collection and RED data processing. The RED data collection program controls the transmission electron microscope and the camera. Electron beam tilts at a fine step (0.05-0.20°) are combined w...
متن کاملElectron Diffraction Electron Diffraction
This guide sheet outlines a method for the analysis of cubic crystal forms, this being useful to you for interpreting the transmission diffraction pattern produced by scattering electrons off a thin film target of polycrystalline aluminium. The apparatus also contains samples with hexagonal structures. These are pyrolytic graphite targets, and are available both as single crystals and in polycr...
