摘要

Abstract—

A method for studying the components of the light detection system of the Liquid Argon Time-Projection Chamber (LArTPC) of the Near Detector of the DUNE experiment (DUNE ND) in liquid argon is presented. As part of the methodology, comparative tests of a full-scale light collection module for a liquid argon time-projection chamber and a shortened module were carried out using a cryogenic stand. The light detection efficiency of the full-scale module observed in the study is ~5% less than that of the shortened module. The full-scale module is shown to be suitable for designing the LArTPC Near Detector for the DUNE experiment.
