Ultrafast sources of Particles and X rays (UPX)

The UPX research group ( Ultrafast sources of Particles and X rays) focuses on the study of fundamental aspects of laser plasma interaction in the relativistic regime, on the development of plasma-accelerators, on the development of ultrafast x-ray or XUV sources from intense femtosecond lasers, and on the application of these secondary sources. This is a long-standing activity at LOA that has started in the 90’s. The group is a recognized as a world leader in these fields with many pioneering results obtained all along the years.

Current activities are organized around 5 main topics: laser wakefield acceleration, relativistic X-ray sources, plasma wakefield acceleration, quantum electrodynamics experiments and soft-X-ray sources.
