“…The direction of the electron beam at the interaction section aligns closely with that of the gamma beam to the experimental area [7], therefore, introducing the electron beam from the end of the LINAC into the injection section at the storage ring redirects the electron beam by 180 degrees. Given the geometrical constraints in the accelerator hall for the storage ring, the electron beam in the transport line must be elevated vertically to a plane that parallels the storage ring, then undergo a 180-degree turn, followed by a vertical transport down to the storage ring's plane towards the injection point.…”

The Variable Energy Gamma (VEGA) System, currently under construction at Extreme Light Infrastructure-Nuclear Physics (ELI-NP), is a storage ring-based gamma beam source that aims to provide gamma-ray beams with a variable energy range from 1 MeV to 19.5 MeV to the users. The electron beam transport line has been designed to connect the linear accelerator and the storage ring in the VEGA electron beam system. Considering the geometrical constraints in the accelerator halls and the location of the injection point at the storage ring, the trajectory of the electron beam in the transport line has to first ascend by a 36-degree dog-leg elevation to align with a plane parallel to the storage ring, undergo a 180-degree horizontal turn, and then descend by 36 degrees vertically to reach the injection point at the storage ring. In this paper, we introduce a beam optics tool implemented for the beam optics design and fine-matching in the electron beam transport line. The design of the VEGA transport line including the layout and lattice design, is also described. The tool has been applied to the beam optics design and optimization, utilizing tracking simulations and beam matching for the VEGA transport line lattice. Furthermore, the tool's potential application to similar lattice designs is also discussed.

“…For this purpose, a family of instruments was constructed. For example, photoneutron cross sections will be measured with the ELIGANT-TN setup [12], while the ELIGANT-GN detector array [12,13] will be used for measurements of γ rays and neutrons emitted during the deexcitation PDR or GDR states above the particle evaporation threshold.…”

An overview of the main directions of present-day studies with quasimonochromatic γ beams is presented with an emphasis on the research opportunities which will be provided to the users at the Extreme Light Infrastructure Nuclear Physics (ELI-NP) facility at Magurele near Bucharest. Experiments with γ beams at the extremes of high temperature and high neutron-to-proton ratios will be discussed. The opportunities for nuclear structure studies with γ rays with orbital angular momentum (OAM) are outlined and a few selected physics problems and classes of experiments, related to, e.g., changes of photonuclear cross sections in reactions with OAM photons, as well as the possibility to address nuclear excitations with higher multipolarity are discussed. The perspectives for studies of exotic nuclei within the Gamma Factory experiment at CERN are discussed, too.

“…Substantial shielding of the array would be needed to protect from Compton scattering sources. Potential integration of a compact silicon detector array should be explored with γ-ray and neutron detector arrays currently available at HIγS and with the ELIADE [48] and ELIGANT [49] arrays under development at ELI-NP.…”

Measurements of (γ, p) and (γ, α) photonuclear reaction cross sections are relevant for several nucleosynthesis scenarios, from the primordial Big Bang, to stellar burning, and the p-process. Studies of photonuclear reaction cross sections marked a steady development in the last 20 years with the advent of mono-energetic γ-ray beam facilities and improved detection methods. Charged-particle detection from photon-induced reactions in solid targets is mainly achieved with silicon-strip detectors, while time projection chambers were developed for measurements with active gas targets. This review tracks the evolution of charged-particle detection methods and highlights recent 7 Li(γ, t) 4 He and 16 O(γ, α) 12 C cross section measurements using mono-energetic γ-ray beams.
