Comprehensive Design and Experimental Validation of 30 kV Ultra‐Fast Flexible Controllable Arresters for HVDC Systems

High Voltage, EarlyView.
ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...
