DESCRIPTION:ARIADNE\, a state-of-the-art 1-ton two-phase Liquid Argon Time
  Projection Chamber (LAr TPC)\, features a game-changing photographic read
 out utilising photon sensitive cameras to image the secondary scintillatio
 n 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 T
 PC with photographic capabilities to be positioned at a charged particle b
 eamline\, and we successfully imaged beautiful LAr interactions with 1 mm 
 track resolution at momenta between 0.5 GeV to 8 GeV. Recently\, we have b
 een successfully working on a further enhancement of the detector by integ
 rating 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 s
 patial resolution just based on light. The system is ideal for colossal du
 al phase LAr neutrino detectors. Results from the beam-test and the 3D Tim
 ePix3 TPC system will be presented detailing the many benefits and capabil
 ities of this technology.
