Summary: The lattice upgrade of the Shanghai Synchrotron Radiation Facility (SSRF) involved replacing bending magnets, constructing two DMB systems, and installing a superconducting wiggler. The symmetry of the storage ring was destroyed, necessitating modifications to the global optics. The lattice design matched the new elements and achieved sufficient dynamic aperture and energy acceptance through elaborate design and optimization.

Summary: A 3W1 superconducting wiggler (SCW) with a 68 mm pole gap was successfully tested and installed in a BEPC II storage ring in November 2019. The goal of zero liquid helium consumption was achieved, and the cryogenic system exhibited a 12% residual cooling capacity (approximately 0.69 W @4.2 K). The 3W1-SCW was set to operate at 2.49 T and has been in operation for over seven months. Three instances of magnet quenching occurred during normal operation. The evaporated helium gas can be recycled to the helium gas recycling system when the pressure in the helium tank exceeds the parameter value (setpoint pressure value is 1.2 bara). The cryogenic system can be recovered within 4 hours if sufficient liquid helium is available for injection into the cryostat.

Summary: A new X-ray imaging and biomedical application beamline (BL13HB) has been implemented at the Shanghai Radiation Synchrotron Facility (SSRF) to facilitate 2D and 3D static and dynamic X-ray imaging. BL13HB utilizes a super-bending magnet as the X-ray source and is equipped with new equipment to accommodate various experimental methods. The experimental station of the beamline is specifically designed for in situ dynamic experiments and has been open to users since June 2021.

Summary: In this study, an ID orbit feedforward compensation system based on a response matrix using corrector coils was developed, and it was successfully applied to all commissioned IDs in the SSRF storage ring, achieving effective orbit distortion compensation. Optical and coupling feedforward systems were also developed, further optimizing the system performance through the installation of quadrupole and skew quadrupole magnets.

Summary: The influence of X-ray mirror errors on beamline performance increases with the improvement of X-ray beam coherence in advanced light sources. Selecting appropriate merit functions to express light distribution and understanding their relationship to optical error is crucial in beamline design. A high-efficiency wave-optics simulation platform and deterministic analysis model were developed to address this issue. The encircled energy radius was proven to be a good metric for the spatial dispersion of the X-ray beam, matching the Church-Takacs theory. It was also found that limiting the contribution of low-frequency errors is effective for specifying the requirements of X-ray mirrors.

Summary: Historically, thermal radiation was thought to be related to 3D cavities, but in practice, it is known that almost any hot surface radiates according to Planck's law. This universality is due to the smooth electromagnetic mode structure of free space. By studying a strongly patterned mode structure, researchers used quasi-transparent point-like thermal light emitters as probes to observe the effects on thermal radiation.

Summary: In order to meet the stability requirements for the exit beam during energy scanning in multi-wavelength anomalous scattering experiments at Shanghai Synchrotron Radiation Facility (SSRF), strict specifications were placed on the double-crystal parallelism of the double crystal monochromator (DCM). By optimizing the second crystal, improving the flexure hinge structure, and reducing weight for related structural parts, the parallelism in the pitch direction was effectively improved, significantly consolidating the foundation for stability improvement of the DCM exit beam.

Summary: This study discusses the magnetic lattice selection and parameter optimization for a fourth-generation light source. Through comparing different lattice cells, a lattice with low emittance and large dynamic aperture was developed for SKIF. The research found that only two families of sextupoles are needed to provide sufficient dynamic aperture and energy acceptance for efficient injection and beam lifetime.
