Description
The Extreme Light Infrastructure – Nuclear Physics (ELI-NP) facility under implementation is projected to provide the European community with the highest brilliance gamma beam to date for physics experiments utilizing photonuclear reactions. One vital family of instruments implemented and ready for the operational phase with the Variable Energy Gamma-ray (VEGA) system is ELI Gamma Above Neutron Threshold (ELIGANT). ELIGANT consists of two complementary setups: ELIGANT Thermal Neutron (ELIGANT-TN) is an array of $^{3}$He counters embedded in a polyethylene matrix, and ELIGANT Gamma Neutron (ELIGANT-GN) comprises EJ-301 liquid scintillator detectors and GS20 $^{6}$Li glass detectors for spectroscopy of both fast and slow neutrons, and a mixed array of CeBr$_{3}$ scintillators and LaBr$_{3}$:Ce scintillators for γ rays. Dedicated digital data acquisition systems read out these detector systems. In addition to the VEGA system, ELI-NP also houses three high-power laser-system (HPLS) beamlines with 100 TW, 1 PW, and 10 PW of power, respectively. The extremely harsh environment, both in terms of electromagnetic intensity and the intensity of the radiation field, the HPLS environment induces, puts additional strong constraints on candidate neutron-detection systems. Recent developments for neutron detection systems with these constraints will also be discussed.
