Fast Small-Angle X-Ray Scattering Tensor Tomography: An Outlook into Future Applications in Life Sciences.

ABSTRACT: Small Angle-X-ray Scattering Tensor Tomography (SAS-TT) is a relatively new but powerful technique for studying the multiscale architecture of hierarchical structures particularly relevant to life science applications. Currently, the technique is very demanding on synchrotron beamtime, which limits its applications, especially for cases requiring a statistically relevant number of samples. This study reports the first SAS-TT measurement at a macromolecular X-ray crystallography beamline, PX-I at the Swiss Light Source (SLS), with an improvement in acquisition time from 96 h/Mvoxel in the pilot experiments to 6 h/Mvoxel with comparable sampling, defining a new standard for fast SAS-TT with a micrometer beam size and allowing to record a full tomogram in 1.2 h. Measurements are performed on
