Above: The UR5e robotic arm inside the ALS SAXS/WAXS beamline hutch (May 2025). Development of high-throughput GIWAXS capabilities is underway as part of the ALS Radius Robotics project. (Left) UR5e mounted invertedly; (Middle) extended UR5e above the sample tray table; (Right) The sample tray table folded up against the hutch wall.

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 "Diffraction and Imaging' program in the Photon Science/Operations" group at ALS. 

- The 'Diffraction and Imaging' program consists of SAXS/WAXS (7.3.3), Tomography (8.3.2), Diffraction Under Non-Ambient Conditions (12.2.2), Small-Molecule Crystallography (12.2.1) and Micro-diffraction (12.3.2). please find more details here

Also, if you need help shipping packages back to your home insitution, it is strongly recommended that you bring return shipping labels and relevant MSDS for any samples/solutions.  Please drop off your prepared boxes off  ALS shipping/receiving in B53 before you leave ALS.  This will greatly speed up the process. Thank you.
