Beamtime at MAX IV in Sweden
From November 4 - 11, 2024, Johannes Viehmann, Yusaku Terao, Simeon Bürger and Niklas Golchert experimented at the FinEstBeAMS beamline of the synchrotron radiation facility MAX IV in Lund, Sweden. Here they installed the EPIC setup (short for electrons and photons in coincidence) to measure multi-electron photon coincidence spectra of pure neon and mixed neon-krypton clusters. One focus was on the suppression of the ICD (short for: Interatomic Coulombic Decay) process by the presence of a neighboring ion within a cluster.

Beamtime at PETRA III in Hamburg
From 22 - 29.10.2024 Emilia Heikura, Adrian Krone, Andreas Anschütz, Dana Bloß and Madhusree Roy-Chowdhury, actively supported by Florian Trinter (FHI Berlin), conducted an experiment on the distance dependence of photoelectron circular dichroism, an effect that occurs during the ionization of chiral molecules by circularly polarized light. For this purpose, a molecular jet was crossed with circularly polarized synchrotron radiation, provided by the P04 beamline of the PETRA III storage ring, and the emitted electrons were measured with a VMI spectrometer (short for Velocity Map Imaging).
