The development of high power lasers and the combination of such novel devices with accelerator technology has enlarged the science reach of many research fields, in particular particle and nuclear physics, astrophysics as well as societal applications in material science, nuclear energy and applications for medicine. The European Strategic Forum for Research Infrastructures has selected a proposal based on these new premises called the Extreme Light Infrastructure (ELI). The ELI will be built as a network of three complementary pillars at the frontier of laser technologies. The ELI-NP pillar (NP for nuclear physics) is under construction near Bucharest (Romania) and will develop a scientific program using two 10 PW lasers and a Compton back-scattering high-brilliance and intense low-energy gamma beam, a combination of laser and accelerator technology at the frontier of knowledge. This unique combination of beams that are unique worldwide allows us to develop an experimental program in nuclear physics at the frontiers of present-day knowledge as well as society driven applications. In the present paper, the technical description of the facility as well as the new perspectives in nuclear structure, nuclear reactions and nuclear astrophysics will be presented.

“…Various improvements were conducted to enhance the performance. [7] For example, we improved the alignment precision of the collimator, the spatial-and-temporal collision precision of the laser and electron beams, intensity and stability of the LCS photons, and so on. We made an electron accelerator system that could be operated by one person, so that users could tune the LCS photon energy and intensity online.…”

This paper consists of four chapters. In chapter 2, technical issues will be discussed. Chapter 3 discusses the process of selection and integration of technologies for bridging, in correspondence to (1) ~ (3) listed above. Chapter 4 reflects on the process of selection and integration of the elemental technologies in correspondence to (4), and discusses the efforts spent to achieve the goals and results. 2 Technical issues about laser Compton scattering There are attractive technologies in nuclear physics and elementary particle physics especially in radiation measurement technologies. They are highly sophisticated, and can be applied to industrial technology with some modifications. We applied a method for measuring cross-sections of atoms and nuclear reactions to nondestructive testing via industrial radiography. Industrial radiography is an important technique in improving reliability of industrial products such as automobiles, aircraft, rockets, sintered materials, cast products, and electronic substrates. [1] A high-energy X-ray computerized tomography (CT) system using an electron accelerator that is capable of radiographing a whole engine block at spatial resolution of 2~3 mm has been developed. In infrastructure diagnosis, the technology to inspect roadbeds and bridges on site using a portable electron accelerator has been developed recently. [2] A nondestructive and highly precise method for visualizing reinforcing steel-bars and cracks in concrete structure is strongly demanded in our society.

“…Thus enhancing PET (positron emission tomography) with an additional gamma, a much better spatial resolution could be obtain. Large penetration, submilimeter dimension, low divergence, tuneable energy are features of ELI-NP gamma beams very suitable for radiography and tomography as non-destructive testing application [19,20] of interest for the large-size and complex products, high resolution investigation in aeronautics, automotive, die-cast or sintered industries, new materials and technologies development, for archaeological artifacts and work of art objects analysis.…”

The spectacular progress of electron and heavy-ions acceleration driven by ultra-short high-power laser has opened the way for new methods of investigations in nuclear physics and related fields. On the other hand, upshifting the photon energies of a high repetition TW-class laser through inverse Compton scattering on electron bunches classically accelerated, a high-flux narrow bandwidth gamma beam can be produced. With such a gamma beam in the 1-20 MeV energy range and a two-arms 10-PW class laser system, the pillar of "Extreme Light Infrastructure" to be built in Bucharest will focus on nuclear phenomena and their practical applications. Nuclear structure, nuclear astrophysics, fundamental QED aspects as well as applications in material and life sciences, radioactive waste management and homeland security will be studied using the high-power laser, the gamma beam or combining the two. The article includes a general description of ELI-Nuclear Physics (ELI-NP) facility, an overview of the Physics Case and some details on the few, most representative proposed experiments.
