Abstract: 4B8 beamline at Beijing Synchrotron Radiation Facility (BSRF) is based on the previous 3B1B beamline with some modification. This beamline will focus on the advancement of vacuum ultraviolet circular dichroism (CD) spectroscopy for studying secondary structure of proteins. Along with beamline moving, some measurements are taken to overcome the exposed problems in 3B1B, such as optical contamination, high stray light level. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]

Abstract: The new 4B8 beamline provides UV-VUV light in the wavelength range from 360 to 120 nm. It uniquely enables two kinds of spectroscopy measurements: synchrotron radiation circular dichroism spectroscopy and VUV excited fluorescence spectroscopy. The former is mainly used in protein secondary structure studies, and the latter in VUV excited luminescent materials research, Remote access to fluorescence measurement has been realised and users can collect data online. Besides steady-state measurements, fluorescence lifetime measurements have been established using the time domain method, while a laser-induced temperature jump is under development for protein folding dynamics using circular dichroism as a probe.
