Oral presentation
The development of free electron lasers in the X-ray regime has opened up new frontiers in X-ray imaging. With X-ray pulses of only a few femtoseconds duration and sufficient peak power to produce high-quality diffraction patterns from a single pulse, recent experiments at the Linac Coherent Light Source (LCLS) have demonstrated structural determination from both isolated viruses and streams...

The single photon counting pixel detector Medipix2 is a powerful tool for energy resolved X-ray imaging. It allows discriminating energy of incoming X-rays by setting an energy threshold common to all pixels. As parameters of individual pixels vary, each pixel further contains a 3-bit digital-to-analogue converter (DAC) adjustment. Values of these DACs are traditionally determined by finding...

Oral presentation
Modern laboratory X-ray imaging systems with microfocus source and CCD camera give us the possibility to move some of modern imaging techniques from synchrotrons to laboratories. Spatially coherent X-rays emited from microfocus source traverse a sample with phase shift. Beam deflection induced by the local change of refractive index may be expressed as dark-bright contrast on the edges in...
