High Intensity Physics

The PHI group studies the physical phenomena involved in laser coupling with matter, whether solid or gaseous, in the relativistic regime for irradiances above a threshold irradiance beyond which electrons reach a kinetic energy greater than their rest energy.

  • ANR FemtoDose Project (2022-2026)

    ANR FemtoDose Project (2022-2026)

    Nanocoulomb femtosecond laser plasma gas pedals with plasma mirror injectors: high doses at very high dose rates In-vivo experiments have shown that healthy tissue (vs. diseased tissue) is much less sensitive to ionizing radiation when delivered in short pulses. This high-dose-rate radiotherapy (RT), also known as RT-FLASH, opens the way to highly innovative new medical…

  • EPONA project (2021-2026)

    EPONA project (2021-2026)

    The aim of the EPONA project (BPI-FRANCE) is to study and demonstrate the purification of palladium from nuclear reactor fission products by laser isotope separation in atomic steam.

  • EURO-LABS (WP5) project (2022-2026)

    EURO-LABS (WP5) project (2022-2026)

    The EURO-LABS project aims to bring together 3 research communities in nuclear physics, gas pedal technologies and detectors for high-energy physics to address fundamental questions and technological challenges, through projects with a broad societal impact, promoting the sharing of knowledge between different scientific fields and strengthening Europe’s potential to successfully meet future challenges. The PHI…

  • MultiScan 3D project (2021-2025)

    MultiScan 3D project (2021-2025)

    The European Multiscan 3D project aims to improve the control of illicit materials, particularly in shipping containers, using a 3D imaging technique based on X-ray tomography generated by braking radiation emitted by electrons created and accelerated by intense femtosecond laser beams. This project has received funding from the European Union’s Horizon 2020 research and innovation…

  • SCiRQ project (2023-2027)

    SCiRQ project (2023-2027)

    The ANR-funded SCiRQ project aims to set up a quantum simulation platform based on circular Rydberg states of strontium. The project leader is Sébastien Gleyzes from the Laboratoire Kastler-Brossel and Collège de France, with LIDYL providing theoretical support.
