DESCRIPTION:Speakers: Konstantinos Mavrokoridis (University of Liverpool)\
 nOptical readout of large scale dual-phase liquid Argon TPCs is an\nattrac
 tive and cost effective alternative to charge readout. Following\nthe succ
 essful demonstration of 3D optical readout with the ARIADNE\n1-ton detecto
 r\, the ARIADNE+ experiment was deployed using the protoDUNE\n“cold box
 ” at the CERN neutrino platform imaging a much larger active\nregion of 
 2mx2m. ARIADNE+ uses 4 Timepix3 cameras imaging the S2 light\nproduced by 
 16 novel\, patented\, glass THGEMs. ARIADNE+ takes\nadvantage of the raw T
 imepix3 data coming natively 3D and zero\nsuppressed with a 1.6 ns timing 
 resolution. Three of the four THGEM\nquadrants were visible readout with t
 he fourth featuring a VUV light\nimage intensifier\, thus removing the nee
 d for wavelength shifting\naltogether. Cosmic muon events were recorded su
 ccessfully at stable\nconditions providing the first demonstration for its
  use in kton scale\nexperiments such as DUNE.\n\nIn my talk I will be disc
 ussing in detail the innovative ideas that make\nARIADNE+ unique and the b
 enefits that come with these technologies.\nThese include\, but are not li
 mited to\, TPX3Cams\, PEN wavelength\nshifting\, a chemically etched stain
 less steel extraction grid\, Invar\nsupport structure and a new way to man
 ufacture glass THGEMs. Future\nplans and a road map towards an even larger
  demonstration using the ProtoDUNE\ncryostat itself for a dedicated dual p
 hase optical run will also be\ndiscussed.\n\nhttps://indico.tlabs.ac.za/ev
