12-ID-B is built and optimized for SAXS applications.
Beamline Overview
The Sector 12 insertion device beamline was upgraded in FY 2012 to a canted undulator arrangement. The beamline uses a large horizontal-offset monochromator, horizontal and vertical focusing mirrors, and a series of slits to deliver photons higher than 1E12 in the size of beam about 200 (H) x 40(V) um^2. The beam size can be slitted down to the size of about 10x10 um^2 if needed.
SAXS Chamber
Built to house the Pilatus 2M, this vacuum chamber provides automatic computer controlled q-range changes by varying the detector distance to experimental sample. An array of motorized beamstops protects the detector from the direct x-ray beam. A smaller Pilatus 300K detector protrudes into the lower front section for simultaneous WAXS data collection.
Sample Environments
A comprehensive suite of sample environments has been developed to accommodate user needs and encourage high-throughput operation for both on-site and remote operations. For more information, see Sample Environments and Remote Setup.

Remote operation utilizes a robotic arm to position user samples.
One of the beamline's most recent developments is the installation of a robotic arm near the sample area to assist with remote access experiments. Users are able to position sample plates into the beam and switch between sample plates using the Remote Operations GUI.
