The beamline control and data acquisition software at the BL19U2 beamline follows the protocols developed by the SSRF. This software is completely adapted to the experimentalist’s needs with a userfriendly graphical user interface (GUI). This GUI displays several important beamline parameters such as the incident flux and the transmitted flux measured at the pin-diode mounted in the beamstop. Relevant parameters such as exposure time, image file name and sample description can also be set in the GUI and transmitted to the Pilatus 2M operating program, which triggers the data acquisition by opening the experimental shutter.

A fully automated and highthroughput SAXS data analysis pipeline, SAS-cam was developed primarily based on the SASTBX package. Five modules are included in SAS-cam, encompassing the data analysis process from data reduction to model interpretation. The model parameters are extracted from SAXS profiles and stored in an HTML summary file, ready for online visualization using a web browser.
