The Short-Baseline Near Detector (SBND) is a Liquid-Argon Time Projection Chamber (LArTPC) currently under construction at Fermilab. SBND is one of three detectors that make up the Short Baseline Neutrino (SBN) program, which aims to investigate the excess of low-energy electron-like events observed by the MiniBooNE and LSND experiments, as well as perform high-precision neutrino-argon cross section measurements. SBND plans to use a novel light collection system which includes X-ARAPUCA devices, made up of a series of dichroic and wavelength-shifting filters that collect photons using SiPMs. This X-ARAPUCA system is also the light collection technology planned for the future DUNE experiment. This talk will give an overview of the X-ARAPUCA system in SBND as well as cover the current status of testing and implementation.
