摘要

Purpose

With the upgrade of the Beijing Electron Position Collider (BEPC) II to BEPCII-U, the Beijing Synchrotron Radiation Facility (BSRF) has also been upgraded accordingly. This paper aims to introduce the functions of the new experimental station at beamline 1W2B of BSRF for users’ reference.

Methods

An additional carbon filter is installed in front of the first optical element (FOE) to absorb the unwanted low-energy beams and reduce the thermal load. The function of experimental station is changed from protein crystallography to combined measurements of small-angle X-ray scattering (SAXS), X-ray diffraction (XRD), and X-ray absorption fine structure (XAFS). And several liquid sample cells to provide in situ environmental conditions were developed. High-frequency sampling technique, bidirectional scanning strategy, fast electronic system, Mythen detector, miniature diamond film detector, etc. are used to implement the SAXS/XRD/XAFS combined technique, and the technical details of this combined technique have been published elsewhere.

Results

The in situ SAXS/XRD/XAFS combined technique at beamline 1W2B can be used to detect simultaneously the local atomic structure, nanoscale structure, and long-range ordered structure with time resolution in seconds. This paper gives these parameters of beamline, experimental station, and sample environmental cells for user to optimize measurement conditions.
