Abstract

At the Extreme Light Infrastructure - Nuclear Physics facility (ELI-NP), high-power laser systems together with high-brilliance gamma beams are the main research tools. The status of the construction of the facility is reported. The emerging photofission experimental program with brilliant gamma beams at ELI-NP is presented with emphasis on the prepared day-one experiments. The physics cases of the flagship experiments at ELI-NP are discussed, as well as the related instruments which are under construction for their realization.

Highlights

  • The Extreme Light Infrastructure (ELI) Pan-European facility aims at research using extreme electromagnetic fields

  • The Extreme Light Infrastructure – Nuclear Physics (ELINP), which is under construction in Magurele, Romania, is one of the three laboratories of ELI, and is focused at the utilization of extreme electromagnetic fields for nuclear physics and quantum electrodynamics research and applications

  • The equipment is placed in the ELINP laboratory complex, in a clean room built on an anti-vibration slab which is specified of having a power spectral density of the vibrations at the level of 10−10 g2/Hz in the frequency range from 1 Hz to 200 Hz [3]

Summary

Introduction

The Extreme Light Infrastructure (ELI) Pan-European facility aims at research using extreme electromagnetic fields. The Extreme Light Infrastructure – Nuclear Physics (ELINP), which is under construction in Magurele, Romania, is one of the three laboratories of ELI, and is focused at the utilization of extreme electromagnetic fields for nuclear physics and quantum electrodynamics research and applications. The main research tools at ELI-NP are a two-arm high-power laser system (HPLS) and a high-brilliance gamma-beam system (GBS) [2,3]. There are two interaction points, one for each stage of the electron accelerator, providing gamma beams with energies up to 3.5 MeV and up to 19.5 MeV, respectively. It is worth noting that these studies will be complimented by research within the HPLS experimental program which includes investigation of the fission-fusion reaction mechanism [9] This will be achieved by reactions of laser-driven actinide beams on deuterium targets [10]
