In-beam characterization of ELISSA: The 4 π position-sensitive silicon strip array at ELI-NP

Extreme Light Infrastructure Silicon Strip Array (ELISSA), the silicon strip detector array developed at the Extreme Light Infrastructure - Nuclear Physics (ELI-NP) facility in collaboration with the Instituto Nazionale de Fisica Nucleare - Laboratori Nazionali del Sud (INFN-LNS), is a 4 π position-sensitive silicon strip array. The array is specifically designed to measure charged particles coming from photodisintegration reactions relevant for p-process nucleosynthesis and supernova explosions. The first in-beam tests of the ELISSA experimental set-up were performed at the 3 MV Tandetron accelerator of National Horia Hulubei National Institute for Research and Development in Physics and Nuclear Engineering (NIPNE). During this in-beam performance test, both analog and digital electronic modules were used to process the data. The performances (such as angular coverage, energy, and position resolution) of the silicon strip array are detailed in this paper. Alongside the measured characteristics, the simulation of the ELISSA array and a comparison of two read-out electronic chains and the two DAQ systems were also included.
