Description
LEGENDArYno is a newly constructed liquid argon (LAr) R&D setup located at LNGS. Its primary purpose is to provide suitable, realistic conditions for testing prototype Light Detection Modules (LDMs) envisioned for the Outer LAr volume instrumentation of the future LEGEND-1000 detector. The experimental setup is housed in a 140-cm-tall, 40-cm-diameter cryostat equipped with liquid nitrogen cooling, a LAr purification system, LAr purity monitoring, and a movable 241Am alpha source. This configuration allows for the optical characterization of geometries up to 1 m long and 35 cm wide. The LDM prototypes are based on doped PMMA and a wavelength-shifting (WLS) layer coupled to a SiPM-based light readout. We present a first report on the successful commissioning of LEGENDArYno and the results of LDM prototypes tests performed this year.
