Optical fiber read-out for liquid argon scintillation light

  title={Optical fiber read-out for liquid argon scintillation light},
  author={J. Janicsk'o Cs'athy and T.Bode and J. Kratz and Stefan Schonert and Christoph Wiesinger},
  journal={arXiv: Instrumentation and Detectors},
In this paper we describe the performance of a light detector for Ar scintillation light made of wavelength-shifting (WLS) fibers connected to Silicon-Photomultipliers (SiPM). The setup was conceived to be used as anti-Compton veto for high purity germanium (HPGe) detectors operated directly in liquid Argon (LAr). Background suppression efficiencies for different radioactive sources were measured in a test cryostat with about 800 kg LAr. This work was part of the R\&D effort for the GERDA… 
Wavelength Shifters for Applications in Liquid Argon Detectors
Wavelength shifters and their applications for liquid argon detectors have been a subject of extensive R&D procedures over the past decade. This work reviews the most recent results in this field. We

Background-free search for neutrinoless double-β decay of 76Ge with GERDA
The potential of an essentially background-free search for neutrinoless double-β decay will facilitate a larger germanium experiment with sensitivity levels that will bring us closer to clarifying whether neutrinos are their own antiparticles.
