Accurate Direct Beam Position Now in Image Header

For the MX endstation we’ve characterized the dependence of the direct beam on detector distance and 2-theta. We collected 4 sweeps of the detector from 120mm to 1600mm combined with 2-theta offsets from 0º up to 12º. These are the gnuplot 3D plots of the data. This set of 3D plots uses gnuplots pm3d settings…

Fast SAXS profile computation with Debye formula

FoXS, a new webapp which uses the Debye formula for calculating theoretical scattering profiles, has been made available on the ModBase website. Give it a try to see how it compares to CRYSOL. FoXS is a method for computing a theoretical scattering profile of a structure and fitting of experimental profile. FoXS can be used…
