Elettra HIGHLIGHTS 2024-2025

Meetings, Workshops and Schools Events Elettra Highlights 2024–2025 178 Between November 2024 and July 2025, Elettra Sincrotrone Trieste hosted a rich programme of scientific events. The highlight of the year was the XXIX Users’ Meeting, held in December 2024, which brought together 110 delegates from 16 countries. The event included the QUEST workshop (1) on quantum materials, one of the most dynamic areas in condensed matter physics, and the NETLINCS workshop (2) dedicated to new spectroscopic approaches to molecular chirality. Discussions ranged from exotic electronic states in novel materials to advanced methods for distinguishing chiral molecules, with participants emphasizing the unique contribution of Elettra and FERMI to these frontier research areas. With four thematic sessions, a poster session, and broad international participation, the Users’ Meeting once again confirmed itself as the flagship event for the community of Elettra and FERMI users. The calendar began in November 2024 with the MXCuBE-ISPyB Joint Meeting (3), which gathered more than 80 experts from large-scale facilities worldwide to share ideas on data acquisition software for structural biology and chemistry. In February 2025, the 4th LEAPSInnov Annual Meeting convened 115 researchers from 25 institutions, marking the most attended edition of the project, aimed at reinforcing ties between European light sources and industry. March 2025 saw the kick-off meeting of PACRI (4), a major EU-funded project coordinated by Elettra with 26 partners, focused on developing advanced accelerator technologies in connection with EuPRAXIA and ELI. In the same month, the twelfth edition of DEELS (5) brought diagnostics experts to Trieste to discuss next-generation technologies essential for new light sources, including Elettra 2.0. Training and knowledge transfer were again a priority. In May 2025, Elettra co-organized with the IAEA the sixth Training Workshop on Synchrotron Technologies and Techniques (6), offering lectures, beamline tutorials, and proposal-writing sessions for young scientists from around the world. That same week, a participant of the NEPHEWS - Early Stage Researchers Programme carried out experiments at the XRF and SISSI-Bio beamlines, highlighting Elettra’s role in supporting early-career researchers, who followed another participant of the NEPHEWS - Twinning Programme who also trained on the XRF beamline during spring. June 2025 was marked by FEMTO16 (7), the international conference on ultrafast dynamics, which gathered 220 experts from 28 countries and set a record for scientific contributions, with over 250 abstracts submitted. Organized for the first time by a free-electron laser facility, the conference underscored the transformative role of FELs in femtochemistry and ultrafast science. In July 2025, the symposium “Advancements in High-Resolution Imaging Using Next-Generation Light Sources”, supported by the Italian Ministry of Foreign Affairs, brought together 57 participants from leading institutions including ESRF, PSI, Diamond Light Source, and MAX IV. 3 1 4 2
