COHERENCE 2010

8 Jun 2010, 08:00 → 11 Jun 2010, 17:00 Europe/Berlin

Hotel Hohe Düne, Rostock-Warnemünde, Germany

International Workshop
on Phase Retrieval and Coherent Scattering

The conference, fifth in a series, will be devoted to coherent x-ray physics. Four topics in particular will be considered:

- imaging with coherent x-rays and electrons,
- structure and dynamics via photon correlation,
- opportunities with new sources,
- theoretical and computational methods.

The meeting will take place June 8-11, 2010 at the Hotel Hohe Düne located in Rostock-Warnemünde, Germany.

Please note: Attendees must apply separately for accommodation at the Hotel Hohe Düne and for meeting registration. On-line registration is linked to the conference webpage.

Poster Session Information

The poster session will be held on in Foyer. The poster size is DIN A0 format (0,90 m x 1,20 m (width and height).

1 Coherent Diffractive Imaging of Two and Three-Dimensional Membrane Protein Crystals using XFELs

The potential for imaging biomolecules using fourth generation XFEL sources is now being explored with the commisioning of beamline experiments having begun at the LCLS (Stanford). These experiments will employ the use of coherent X-ray diffractive imaging techniques by collecting snapshot diffraction patterns in a time regime that avoids nuclear damage in biomolecules. The opportunity to perform imaging of single biomolecules (such as membrane proteins) is present. Some membrane proteins form single two-dimensional crystals and submicron single three-dimensional crystals. Diffraction data collected from periodic samples (such as these small membrane protein crystals) will provide both an amplified intensity measurement and additional a priori constraints(the periodicity of the sample) that will benefit image reconstruction. We have simulated the diffractions produced using XFEL radiation for two-dimensional and three-dimensional submicron crystals of the membrane proteins lysozyme, potassium channels and bacteriorhodopsin for upcoming experiments. We seek to perform appropriate phase-retrieval on this data that will lead to high resolution solutions to membrane-protein structures.

Speakers: Prof. Keith Nugent (CXS University of Melbourne), Ms Rebecca Ryan (CXS University of Melbourne)
