Simulations of coherent scattering experiments at storage ring synchrotron radiation sources in the hard x-ray range
Detailed simulations of experiments carried out at modern light sources are directly related to the most efficient and productive use of these facilities for research in multiple branches of science and technology. The “Synchrotron Radiation Workshop” computer code with its Python interface, and Sirepo web-browser-based graphical user interface, currently supports physical optics simulations of coherent X-ray scattering and imaging experiments on user-defined virtual samples. We present examples of simulations of coherent scattering experiments that are typically performed at the Coherent Hard X-ray beamline at Brookhaven National Laboratory’s (BNL) National Synchrotron Light Source II. We also present several comparisons of the simulations with the results of actual coherent X-ray scattering experiments with nano-fabricated test samples produced at BNL’s Center for Functional Nanomaterials.
A long-lived relativistic electron storage ring embedded in Earth's Outer Van Allen belt
Since their discovery over 50 years ago, the Earth’s Van Allen radiation belts are thought to consist of two distinct zones of trapped, highly energetic charged particles. The outer zone is comprised predominantly of mega-electron volt (MeV) electrons that wax and wane in intensity on time scales ranging from hours to days depending primarily on external forcing by the solar wind. Thus, the spatially separated inner zone is comprised of commingled high-energy electrons and very energetic positive ions (mostly protons), the latter being stable in intensity levels over years to decades. In situ energy-specific and temporally resolved spacecraft observations reveal an isolated third ring, or torus, of high-energy (E > 2 MeV) electrons that formed on 2 September 2012 and persisted largely unchanged in the geocentric radial range of 3.0 to ~3.5 Earth radii for over four weeks before being disrupted (and virtually annihilated) by a powerful interplanetary shock wave passage.
Tagging system for almost-real photons at VEPP-3 storage ring
At BINP the construction of the tagging system for almost-real photons (TS) is in progress. The energy of tagging photons can be up to 1.5 GeV. The projected energy resolution of TS is better then 1%. For at least a half of photons the linear polarization can be determined. The tagging system will extend the possibilities for photoreaction studying at VEPP-3 significantly. TS would allow to perform a complete kinematics reconstruction, thus permitting a reliable rejection of the background processes; to extend the measurements to higher photon energy; to enabling Σ-asymmetry measurements and double polarization experiments.
Solving protein structure from sparse serial microcrystal diffraction data at a storage ring synchrotron source
This dataset consists of 79,992 diffraction patterns stored in cbf format. A step-by-step tutorial on the reconstruction of the Bragg intensities using the EMC algorithm (Loh & Elser 2009) is described [here](https://github.com/tl578/EMC-for-SMX/wiki). We thank the authors of Martin-Garcia et al. (2017) for their gracious access to the data. Reduced data files: For those who would like to try an EMC reconstruction immediately, the data reduction step can be skipped by downloading the reduced data files provided by us. See [here](https://github.com/tl578/EMC-for-SMX/wiki/Data-reduction#skipping-data-reduction) for more details.
