ELI-NP gamma beam system — New facility for nuclear physics research

The Gamma Beam System at the ELI-NP (Extreme Light Infrastructure — Nuclear Physics) is the future user research facility currently being constructed in Magurele/Bucharest, Romania. The ELI-NP is one of the three pillars of the pan-European research facility Extreme Light Infrastructure [1]. The GBS is the high-brilliance, advanced source of gamma rays, based on the laser Compton back-scattering. It will have unique features in the world such as a high brilliance, small relative bandwidth, tunable energy, and high spectral density [2]. The facility will open new opportunities for nuclear physics research in fields like nuclear photonics, nuclear astrophysics, photo-fission, and production of exotic nuclei, applications in industry, medicine, and space science. The Gamma Beam System was designed and is being constructed by the EuroGammaS Association. This is a consortium of European academic and research institutions and industrial partners. In the paper overview of the Gamma Beam System at the ELI-NP is given.
