Abstract

Extreme Light Infrastructure – Nuclear Physics (ELI–NP) is the nuclear physics pillar of the pan–European Extreme Light Infrastructure project and it was implemented on the Măgurele National Physics Platform in Romania. Two scientific communities, in laser physics and nuclear physics, have joined forces at ELI-NP to develop new research topics arising from the interaction of extreme photon beams with matter. At the heart of the project are two state-of-the-art extreme light sources: a high-power 2 x 10 PW ultra-short-pulse laser system and a high-intensity gamma beam system delivering beams with unprecedented characteristics. Several experimental setups have been implemented at ELI-NP, specifically designed to take advantage of these extreme photon beams.
A rich science program was established within a large international collaboration with the aim to advance the field of Nuclear Photonics. The basic scientific research aims to reveal the mechanisms underlying the acceleration of particles driven by high-power lasers and to enable exotic nuclear physics experiments under plasma conditions to reproduce the evolution of the stellar environment in the laboratory. Gamma beams will allow the study of electromagnetic dipole response of nuclei and nuclear reactions of astrophysical interest. The results of the basic research will enable new applications in life sciences, industry and medicine.
An extensive biomedical research program, anchored in ELI-NP's unique capabilities, is currently being developed and addresses topics such as: radiotherapy-relevant nuclear beam production, radiobiological effects of laser and gamma nuclear beams, medical imaging research using laser-driven X-ray sources and medical isotope production research.
The high–power laser system is operational since 2020 and a thorough program of experimental setups commissioning was performed since then. The experimental setups at 100 TW and 1 PW laser powers were successfully commissioned and are available for users. The 10 PW experimental setups are under commissioning and they will become available to users in 2024. ELI–NP started the operation as user facility in 2022 when the first call for users was launched in close collaboration with ELI ERIC.
The intense gamma beam system is under construction and will start operation in 2026. The experimental setups for the gamma beam were implemented providing state–of–the–art devices for nuclear physics studies. A preparatory experimental program is currently being performed with these detection setups on complementary science topics with the gamma beam-based studies.
The ELI-NP project Phase II is co–funded by the European Union through the European Regional Development Fund and by the Romanian Government through the Competitiveness Operational Program.
