Coherent X-ray imaging and dynamics

This week’s journal club item is a Science magazine review article by Gaffney and Chapman on imaging of atomic structure and dynamics using coherent x-ray beams, ultrafast x-ray beams and the combination of the two. Even though most of the coherent x-ray imaging part of the review is understandably focused on single-molecule imaging, the paper provides a very nice overview of the extremely bright future, and also of some key challenges.

This quote is quite remarkable, in providing a nice comparison of future vs. present/past sources: “At the LCLS, the integrated x-ray production in 10 s of lasing will exceed the total x-ray photon production at the SPPS during its 3-year lifetime.”

It’s also interesting to note that the review is published in Science, a relative newcomer to coherent x-ray field heavily dominated by Nature and more recently also by Nature Physics.
