Abstract
In this document, the assembly and characterization procedure of 74 out of 160 X-Arapucas implemented as the Photon Detection System for use in the ProtoDUNE-SP run II is presented. To carry out this process, a cryogenic system is designed in which 13 X-Arapucas operate simultaneously in liquid nitrogen. The data analysis consisted of gain measurement, signal-to-noise ratio and dark count rate, as well as the study of possible inefficiencies checking the level of light seen by each X-Arapuca. Finally, having verified the correct operation of the X-Arapucas, they have been sent to CERN for their final installation in ProtoDUNE-SP, located at the CERN Neutrino Platform.
