New Master's students
We welcome Sunny Labh and Julian Hertlein as Master students in our group.
We wish you a good time in the AG Ehresmann!
Beamtime at FlexPES
From December 1 - 9, 2025 Dana Bloß, Yusaku Terao, Johannes Viehmann, Emilia Heikura, Joel Herrmann and Madhusree Roy Chowdhury together with our external colleagues Rémi Dupuy and Olle Björneholm performed experiments at the FlexPES beamline of the MAX IV synchrotron in Sweden. ICD (intermolecular Coulombic decay) processes in resonantly excited cations were investigated.
Beamtime at DESY in Hamburg
From 27.11. - 02.12.2025 Mika Ossenschmidt, Arne Vereijken and Yahya Shubbak together with our external colleague from the University of Mainz Timo Kuschel conducted experiments at the DESY P09 beamline of the PETRA III storage ring. The influence of helium ion bombardment on the magnetic proximity effect in platinum was investigated. The measurement method used was resonant magnetic X-ray reflectometry, which is a particularly sensitive method for characterizing magneto-optical depth profiles.
Workshop "Soft X-ray Science at PETRA III"
Arno Ehresmann, Andreas Hans, Emilia Heikura and Dana Bloß took part in the workshop "Soft X-ray Science at PETRA III" in Hamburg from November 17 - 18, 2025, where Emilia Heikura and Dana Bloß presented their scientific work by giving a talk.
