Stanford Synchrotron Radiation Lightsource

The soft x-ray (150 - 1200 eV) coherent scattering beamline is capable of X-ray Fourier Transform Holography (FTH) and resonant Coherent Diffraction Imaging (CDI) with a flux of 2 x 107 photons s-1um-2 at the shortest transverse coherence of 3 um in a spot size of 25 x 250 um on the sample. The distance between the sample and the in-vacuum backside-illuminated CCD detector can be adjusted from 50 to 400 mm. The detector consists of 1340 x 1300 pixels of 20 um. Nanoscale imaging at cryogenic temperatures (15 - 300 K) and the application of magnetic fields up to 0.1 T are also available. Several novel lensless imaging techniques such as HERALDO and reference guided phase retrieval have been demonstrated at this beamline. With the use of a mobile laser hutch, optical pump x-ray probe experiments with picosecond time resolution are possible. In the future, the implementation of X-ray Photon Correlation Spectroscopy (XPCS) will enable observations of real-time dynamics in the microsecond - second range. For details please contact
