摘要

Background

After nearly 20 years of service, beamline 1W1A at the Beijing Synchrotron Radiation Facility undergoes an upgrade.

Methods

To keep the beam spot to its designed specifi cations and to address the challenges posed by the increasement of the storage ring beam current, a newly designed bending mechanism for the monochromator is installed. The experimental setup includes updated equipment such as a 6-circle diff ractometer, a 2-dimensional array detector, a closed-cycle cryostat system, and a grazing incidence wide-angle X-ray scattering experiment system. Furthermore, the control system and user data management software were enhanced to support these hardware updates.

Results and Conclusion

These updates have provided the beamline with more flexible measurement modes and expanded the dimensionality of experimental data, allowing users to conduct in situ experiments over a wide range of sample temperatures. Benifiting from the upgrades, new experimental methods have become available, resultingin significant improvements in both efficiency and resolution.
