dc.abstract.enWe introduce the LUNA neutron detector array developed for the investigation of the13C(,)16O reactiontowards its astrophysical-process Gamow peak in the low-background environment of the LaboratoriNazionali del Gran Sasso (LNGS). Eighteen3He counters are arranged in two different configurations (in avertical and a horizontal orientation) to optimize neutron detection efficiency, target handling and targetcooling over the investigated energy range E,lab= 300 − 400keV (En= 2.2 − 2.6 MeVin emitted neutronenergy). As a result of the deep underground location, the passive shielding of the setup and active backgroundsuppression using pulse shape discrimination, we reached a total background rate of1.23 ± 0.12counts/hour.This resulted in an improvement of two orders of magnitude over the state of the art allowing a directmeasurement of the13C(,)16O cross-section down to E,lab= 300keV. The absolute neutron detectionefficiency of the setup was determined using the51V(p,n)51Cr reaction and an AmBe radioactive source, andcompleted with a Geant4 simulation. We determined a (34±3)% and (38±3)% detection efficiency for thevertical and horizontal configurations, respectively, for En= 2.4 MeVneutrons
