Large Scale Demonstration of 3D Optical Readout for Dual Phase LArTPCs at the CERN Neutrino Platform

Abstract: Optical readout of large scale dual-phase liquid Argon TPCs is an attractive and cost effective alternative to charge readout. Following the successful demonstration of 3D optical readout with the ARIADNE 1-ton detector, the ARIADNE+ experiment was deployed using the protoDUNE “cold box” at the CERN neutrino platform imaging a much larger active region. ARIADNE+ uses 4 Timepix3 cameras imaging the S2 light produced by a novel glass THGEM array. ARIADNE+ takes advantage of the raw Timepix3 data coming natively 3D and zero suppressed with a 1.6 ns timing resolution. Cosmic muon events were recorded successfully at stable conditions providing the first demonstration for its use in kton scale neutrino experiments such as DUNE. In my talk I will be discussing in detail the innovative ideas that make ARIADNE+ unique and the benefits that come with these technologies.
