Scientific Programs and Required Beamline Performance at LiX

samples are also often weak x-ray scatterers, due to the low electron density contrast. X-ray measurements on these samples therefore require high x-ray intensity as well as low x-ray divergence. Taking advantage of the NSLS-II source brightness, the LIX beamline will provide capabilities for transmission and grazing incidence x-ray scattering with tunable beam size and divergence, to support scientific research in three specific areas: 1) structural dynamics of biological molecules in solution on a time scale of tens of microseconds to sub-seconds, 2) structure characterization of planar lipid membranes and the associated membrane proteins, and 3) x-ray scattering-based scanning probe mapping at micron resolution of organic and inorganic matrices in biological tissues.
