Abstract

ARIADNE , a state-of-the-art 1-ton two-phase Liquid Argon Time Projection Chamber (LAr TPC ), features a game-changing photographic readout utilising photon sensitive cameras to image the secondary scintillation light produced in THGEM holes. ARIADNE underwent testing at the T9 beam line, CERN East Area in Spring 2018. ARIADNE is the first two-phase LAr TPC with photographic capabilities to be positioned at a charged particle beamline, and we successfully imaged beautiful LAr interactions with 1 mm track resolution at momenta between 0.5 GeV to 8 GeV. Recently, we have been successfully working on a further enhancement of the detector by integrating an ultra-fast imaging system based on the well-established TimePix3 sensor. With this technology we have now created a dream TPC in which you can take videos of particle interactions with ns time resolution and mm spatial resolution just based on light. The system is ideal for colossal dual phase LAr neutrino detectors. Results from the beam-test and the 3D TimePix3 TPC system will be presented detailing the many benefits and capabilities of this technology.
