Beamline 7.3.3 is a SAXS/WAXS/GISAXS/GIWAXS beamline, covering a wide q range (0.004 - 3 Å−1) and length scale (2 - 1500 angstrom).
We are part of the "Scattering" Program under the "Photon Science/Operations" group at ALS.
- The scattering program consists of hard x-ray scattering (7.3.3), resonant soft x-ray scattering (11.0.1.2), COSMIC XPCS scattering branch (7.0.1), and tender x-ray scattering (5.3.1) which is under development. please find more details here
