CEPC synchrotron radiation beam can be considered as one of the best beams for FLASH radiotherapy after using a physicochemical model to predict the macroscopic therapeutic effect.

The upgrading of BL08U1A has been conducted recently. The energy range reaches 180~2050 eV; the energy resolution reaches 16333 @244 eV, 12730 @401 eV; the photon flux measured in the experimental station is over 2.45×109 photons s-1 (E/ΔE = 6440@244 eV).

Our work presents recent advancements in 3D-printed nozzles for liquid jet spectroscopy, made possible by the availability of nozzle development and testing facilities at EuXFEL, Germany. We also demonstrate the performance of one of these custom-designed nozzles in a new flat jet system under commissioning at MAX IV Laboratory in Lund, Sweden, introducing a new injection method to analyze flat liquid surfaces and opening new possibilities for the spectroscopy community.

FF hyperspectral XAS imaging implemented at a Quick-EXAFS beamline offers the capability to add micrometre-scale information to second time resolution for operando monitoring of functional materials under process condition.

In our study, we have developed an algorithm that effectively corrects and tracks these angular distortions, enabling BCDI to work much more robustly and accurately in a wider range of challenging experimental scenarios.
