Abstract—The future prospects of photonuclear reactions studies at the new Extreme Light Infrastructure— Nuclear Physics (ELI-NP) facility are discussed in view of the pursuit of investigating the electromagnetic response of nuclei using γ -ray beams of unprecedented energy resolution and intensity characteristics. We present here the features of the γ -ray beam source, the emerging ELI-NP experimental program involving photonuclear reactions cross section measurements and spectroscopy and angular measurements of γ -rays and neutrons along with the detection arrays currently under implementation.

1. INTRODUCTION The Extreme Light Infrastructure—Nuclear Physics (ELI–NP) [1] is one of the three pillars of the Extreme Light Infrastructure Pan-European initiative listed on the ESFRI (European Strategic Forum for Research Infrastructures) 2006 road-map, a project distributed among three European countries (the Czech Republic, Hungary and Romania) and funded by the European Commission through Structural Funds. Currently under construction in Magurele, Romania, ELI–NP is expected to be the most advanced research infrastructure in the world focused on photonuclear physics studies and applications at the time when it will become operational, in 2018. It will hosttwo 10 PW lasers and a very brilliant, state-ofthe-art gamma beam system (GBS) and it will cover frontier fundamental physics, new nuclear physics and astrophysics as well as applications in nuclear materials and radioactive waste management, materials science and life sciences [2–4]. We present here the physics program proposed for the GBS at ELI-NP and also we have given details on the experimental setups which are currently under 1 Talk
