As part of the NEPHEWS Twinning Programme, another successful match has been made between an interested synchrotron user and an experienced user group. Claudiu Locovei, from the National Institute of Materials Physics in Bucharest/Romania, recently joined a beamtime led by Prof. Dr. Ralf Roehlsberger (Helmholtz-Institut Jena and DESY), Dr. Lars Bocklage (DESY), and Dr. Sven Velten (DESY).
The research focused on advancing X-ray quantum memories and took place at the High-Resolution Dynamics beamline P01 at PETRA III, DESY Hamburg.
Upon arrival at DESY, Claudiu was welcomed by Lars Bocklage, who introduced him to the general features of P01 beamline and outlined the details of the planned experiment.
“During my stay, I had the opportunity to gain valuable hands-on experience and to contribute to ongoing research on a nuclear frequency comb memory — a continuation of a previous study on quantum memory for hard X-ray photon wave packets”.
In addition to Claudiu’s involvement in the main experiment, Lars also presented laboratories at DESY Photon Science in general, and specifically labs of his research team “Magnetism and Coherent Phenomena” giving Claudiu a more complete understanding of the available preparation and analysis methods.
As an added highlight, Claudiu assisted in the alignment of a multilayer nanosystem and learned to process and analyse data using NEXUS, the Nuclear Elastic X-ray scattering Universal Software.
Summing up his visit, Claudiu said: “Based on this experience, I plan to submit a proposal to study magnetic thin films nanosystems at P01 beamline at PETRA III. These systems cannot be measured in a reasonable time using conventional 57Fe Conversion Electron Mössbauer Spectroscopy. I’m very grateful to Lars and the entire team for introducing me the unique capabilities of the P01 beamline”.
