1. Researcher’s night
(MARIE project, Research and Innovation Programme Horizon Europe, Grant agr. 101061141)
The European Researchers’ Night is a Europe-wide public event, which displays the diversity of science and its impact on citizens’ daily lives in fun, inspiring ways. Researcher’s Night is a celebration of science and research organized every year on the last Friday of September in over 350 cities across Europe. This year, the event took place in 26 countries on Friday 30 September 2022. The participation of the HMU team in the TECHNO-CLS project was presented in the Researcher’s night public event that was held at the Institute of Plasma and Laser Physics (IPPL) in the city of Rethymno https://researchersnight.gr/events/. Below are presented indicative photos and slides from the central speech of Professor Nektarios Papadogiannis and from other presentations that took place regarding the dissemination of the project.
2. Participation in the COST Action TUMIEE (CA17126) meeting in Hamburg
The meeting of the TUMIEE Action of the COST programme took place on December 9, 2022 at the Center for Free-Electron Laser Science CFEL, Deutsches Elektronen-Synchrotron DESY. The HMU team participated in the meeting with a presentation and a poster regarding its intended contribution in the TECHNO-CLS project with titles “Dynamic acoustic bending of crystalline structures for the generation of gamma radiation via undulation of super-relativistic electron/positron beams” and “Multiphysics modeling and simulations of the forthcoming experiments in IPPL”, respectively. The abstract of the presentation and the poster can be found below.
