At the Applied Optics Laboratory (LOA*), the CALYCO Chair aims to develop an industrial laser-plasma acceleration system for non-destructive imaging, with potential applications in the energy, aerospace, and automotive sectors. The project is funded by Institut Pierre Lamoure through the École Polytechnique Foundation.
Through an event bringing together scientists and distinguished guests from the French aerospace sector, the École Polytechnique’s “Space: Science and Space Challenges” Chair reaffirms its key role in educating young engineers in this field, combining research, teaching, and industrial partnerships.
Fiona O’Brien, a student in École Polytechnique’s Master of Science & Technology program “Economics for Smart Cities and Climate Policy”, was invited to present her joint research with Emma Jung, a master's student at TUM, at the TRA (Transport Research Arena). This year, Europe’s largest conference on transport research and innovation took place in Budapest from May 18–21, 2026. Fiona and Emma conducted their research on the impacts of the Paris low-emission zone (ZTL) on mobility and environmental outcomes as part of the “Cities and Transportation” course at l’X.
