ESRF_ID01 InstrumentThis model of ID01 is designed specifically to conduct virtual scanning nano-diffraction imaging experiments such as the one demonstrated Chahine et al., J. Appl. Cryst 47, 762-769. The model includes beam-defining slits, a double Si111-monochromator, a Fresnel Zone Plate, a polycrystalline sample designed specifically for this type of virtual experiments, and a detector set up mimicking the set up at the actual beam-line. The nanodiffraction experiment is performed by locating a suitable peak in the diffraction of the crystal (using the variables NominalEnergy, Delta, and Eta) and then scan across the sample (using the variables Pix and ySamplePosition). By plotting e.g. total detector intensity as a function of position, one can map out impurities in the sample by their scattering properties.
