Management of metadata and automation for mail-in measurements with the APS 11-BM high-throughput, high-resolution synchrotron powder diffractometer

A high-resolution and high-throughput synchrotron powder diffractometer has been automated for use with samples that are mailed in by Advanced Photon Source users. Implementation of a relational database with web interfaces for both outside users and beamline staff, which is integrated into the facility-wide proposal and safety system, allows all aspects of beamline management to be integrated. This system permits users to request kits for mounting samples, to provide sample safety information, to obtain their collected data and to provide usage information upon project completion in a quick and simple manner. Beamline staff use a separate interface to note receipt of samples, schedule and collect diffraction data, post-process and quality-check data, and dispose of samples. The design of the software and database are discussed in detail.
