Altin, J. Härtwig, R. Köhler, W. Ludwig, M. Ohler and H. Klein Synopsis: A versatile bendable monochromator double-crystal diffractometer was constructed, to investigate, using synchrotron radiation, single-crystal samples with high strain sensitivity and without any reduced image sizes. It is based on a local adaptation of Bragg angles between monochromator and sample. Online 31 August 2002

J. Synchrotron Rad. (2002). 9, 293-297  [ doi:10.1107/S0909049502010117 ] Time dependence of the polarization of short X-ray pulses after crystal reflection W. Graeff Synopsis: The time dependence of the polarization of short X-ray pulses is simulated by Fourier transforms using the steady-state solutions from dynamical theory. The mixed states in particular show a very pronounced time dependence, as perpendicular and parallel polarization components have a different time response. Online 31 August 2002
