FOCUS ON COHERENCE - Informal Mini-workshop and kickoff meeting organized by ID01

Aim of the meeting

Since about 3 years ID01 is involved in coherent diffraction imaging on nanocrystals and epitaxial nanostructures. We were planning an internal session of talks on CDI to sum up the current progress in this field at ID01 and to take advantage of the presence of our scientific visitors Virginie Chamard and Rogerio Paniago, who helped us a lot.

In view of the comments coming from some SAC members (who criticized that the different approaches in the CDRs to use the coherence of the beam at the ESRF are rather “incoherent”) I propose to install, in the long run, a “platform on CDI” at the ESRF. The present mini-workshop should be regarded as a kickoff meeting for this proposal.

To this end I have invited the group 1 and also ID10, where the major efforts on CDI are located, to attend the meeting and present their work.  The workshop is however, open to everybody interested at the ESRF.  I think it would be a good opportunity to intensify the contact with the “scisoft people“ and to initiate a joint effort for a common base for data analysis on phase retrieval.
