The advanced light source including Free Electron Laser (FEL) and Synchrotron Radiation Facility, active X-ray optics is very important for X-ray transport with high efficiency in beamlines, which has been proved by the decade’s development and application of bimorph mirrors. In this report, we report a new type of X-ray active optics - the deformable mirror based on thermal-heat effect. Simulation results shows that the mirror provides high spatial resolution over traditional bimorph mirror. In addition, the features of simple process and low cost make it possible to reduce high quality requirement on other X-ray optics.

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.

The BEPC(Beijing Electron‐Positron Collider) is upgraded to be BEPCII, a two‐ring Electron‐Positron collider. Due to the construction of the BEPCII and upgrade of the existing front ends and beamlines, all the existing EPSs(Equipment Protection Systems) have to be redesigned and reconstructed at BSRF. All the redesigned EPSs for the upgrading front ends and beamlines are a PLC‐ and SCADA‐based equipment protection and control and monitoring system. The EPSs are used to protect BEPCII two storage rings vacuum against vacuum failures in a beamline, as well as to protect the front‐end and beamline components from being damaged by synchrotron radiation. For the high‐power wiggler beam lines, a fast movable mask is used to protect the blade of a fast‐closing valve from damage when the fast‐closing valve is triggered to close, which does not need to dump the electron beam running in BEPCII outer ring. In addition, all redesigned PLC‐ based EPSs are used to communicate with the same centralized monitoring comput...
