    Accelerator Physics: HF-Couplers for bERLinPro prove resilient
    In synchrotron light sources, an electron accelerator brings electron bunches to almost the speed of light so that they can emit the special "synchrotron light". The electron bunches get their enormous energy and their special shape from a standing electromagnetic alternating field in so-called cavities. With high electron currents, as required in the bERLinPro project, the power needed for the stable excitation of this high-frequency alternating field is enormous. The coupling of this high power is achieved with special antennas, so-called couplers, and is considered a great scientific and technical challenge. Now, a first measurement campaign with optimised couplers at bERLinPro shows that the goal can be achieved.

    New Materials for Energy Storage: ERC Starting Grant for Tristan Petit
    Dr. Tristan Petit has received a prestigious Starting Grant from the European Research Council for 1.5 million euros over the next five years. The materials researcher will use the grant to investigate a new class of materials known as MXenes for storing electrical energy. MXenes can store and deliver large amounts of electrical energy extremely quickly. They might play an important role in energy storage alongside batteries and supercapacitors. The ERC Starting Grant is one of the most important European research grants.

    BESSY II: Ultra-fast switching of helicity of circularly polarized light pulses
    At the BESSY II storage ring, a joint team of accelerator physicists, undulator experts and experimenters has shown how the helicity of circularly polarized synchrotron radiation can be switched faster - up to a million times faster than before. They used an elliptical double-undulator developed at HZB and operated the storage ring in the so-called two-orbit mode. This is a special mode of operation that was only recently developed at BESSY II and provides the basis for fast switching. The ultra-fast change of light helicity is particularly interesting to observe processes in magnetic materials and has long been expected by a large user community. [...]
