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 کاملDestruction-and-diffraction by X-ray free-electron laser.
It is common knowledge that macromolecular crystals are damaged by the X-rays they are exposed to during conventional data collection. One of the claims made about the crystallographic data collection now being collected using X-ray free-electron lasers (XFEL) is that they are unaffected by radiation damage. XFEL data sets are assembled by merging data obtained from a very large number of cryst...
متن کاملX-ray Diffraction Data Collection
“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 کاملData processing software suite SITENNO for coherent X-ray diffraction imaging using the X-ray free-electron laser SACLA
Coherent X-ray diffraction imaging is a promising technique for visualizing the structures of non-crystalline particles with dimensions of micrometers to sub-micrometers. Recently, X-ray free-electron laser sources have enabled efficient experiments in the `diffraction before destruction' scheme. Diffraction experiments have been conducted at SPring-8 Angstrom Compact free-electron LAser (SACLA...
متن کاملTime Compression of X-ray Free-electron Laser Pulses under Conditions of Bragg Diffraction
In the last years several laboratories actively work on construction of X-ray free electron lasers (XFEL) with wavelength of radiation of the order λ ~ 0.1 nm. Theoretical calculations show, that self-induced amplification of spontaneous radiation on the exit of an XFEL undulator forms a pulse composed of many ultra-short peaks with duration from a fraction up to tens femtosecond. A further tai...
