New status of the infrared beamlines at SSRF

Abstract

There are two infrared beamlines at the Shanghai synchrotron radiation facility (SSRF)—BL01B and BL06B. BL01B was the first infrared beamline of the National Facility for Protein Science in Shanghai at SSRF, which is dedicated to synchrotron infrared microspectroscopy. It utilizes bending magnet radiation and edge radiation as light sources. Diffraction-limited spatial resolution is reached in the infrared microspectroscopy experiment. BL01B has been in operation for approximately five years since it opened in January 2015. In the past few years, many meaningful results have been published by user groups from various disciplines, such as biomacromolecule materials and pharmaceutical, environmental, and biomedical sciences. In addition, a new infrared beamline station BL06B is under construction, which is optimized for the mid-infrared and far-infrared band. BL06B is equipped with a vacuum-type Fourier transform infrared spectrometer, infrared microscope, custom long-working-distance infrared microscope, infrared scanning near-field optical microscope, and mid-infrared Mueller ellipsometer. The purpose is to serve experiments with high vacuum requirements and spatial resolution experiments, as well as those that are in situ and time-sensitive, such as high-pressure and atomic force microscopy infrared experiments. The station can be used for research in biomaterials, pharmacy, geophysics, nanotechnology, and semiconductor materials.
