Abstract
The Helmholtz-Zentrum Hereon, Germany, is operating the user experiments for microtomography at the beamlines P05 and P07 using synchrotron radiation produced in the storage ring PETRA III at DESY, Hamburg, Germany. Attenuation-contrast and phase-contrast techniques were established to provide an imaging tool for applications in biology, medical science and materials science. Within the recent years we built an imaging pipeline to optimize the deliverd radiation dose onto the sample with respect to the applied imaging technique. This became possible by the modernisation of the experiment control and the integration of different imaging detectors. In combination with an new concept for a high-speed X-ray shutter the applied radiation dose can be adjusted from high, for optimization of the statistic within the tomogram, to low, for avoiding any radiation based artefact. Within this talk the recent hardware and software developments integrated to the microtomography imaging system at the beamlinew P05/PETRA III and P07/PETRA III will be presented. Furthermore, the optimization of dose will be demonstrated on selected samples.
