MLL-Kolloquium: Simone Schleede (TU München/E17 and Institute of Medical Engineering (IMETUM)) : First Experiments with a Laser-Driven Compact Synchrotron X-ray Source

Thursday 12 May 2011, 16:00 → 17:00 Europe/Berlin

The Compact Light Source, a laser driven small-size synchrotron developed by Lyncean Technologies Inc., produces x-rays at the intersection point of counter propagating laser and electron beams in the process of inverse Compton scattering. The small size of the intersection point results in a highly coherent beam with a few milliradian angular divergence and three percent energy bandwidth. The intrinsic monochromaticity and coherence of the produced x-rays is exploited in high-sensitivity differential phase contrast imaging with a grating-based interferometer. Hard x-ray Moire wavefront analysis with the grating-based interferometer can be used for time resolved studies of x-ray source size and source position. This allows to precisely detect small fluctuations in collision timing and intersection point position. The Compact Light Source has the potential to yield images of quality previously only attained at large-scale synchrotron facilities, while being a small-size x-ray source which allows it to be installed in hospitals for medical imaging.
