Vertical Drift LAr-TPC for the DUNE Experiment

<!--HTML--><p><span><span><span><span><span style="color:black">The Deep Underground Neutrino Experiment (DUNE) is designed to conduct a broad exploration&nbsp;of the three-flavour model of neutrino physics with&nbsp;unprecedented details in the determination of the neutrino mass hierarchy and&nbsp;</span></span></span><span style="color:black">CP violating parameters.&nbsp;</span></span></span></p> <p><span><span><span><span><span style="color:black">The experiment will rely on an intense neutrino beam from Fermilab on several&nbsp;far detectors located in the SURF underground laboratories at&nbsp;1300 km distance.&nbsp;</span></span></span></span></span><span><span><span><span><span style="color:black">The selected LAr-TPC technology combines fine-grained tracking with total absorption calorimetry to provide a detailed view of any particle interaction.&nbsp;</span></span></span></span></span><span><span><span><span><span style="color:black">In particular the extremely large LAr purity and the very low electronic noise allows for longer drifts and &nbsp;less readout planes.</span></span></span></span></span></p> <p><span><span><span><span><span style="color:black">The Vertical Drift (VD) concept exploits these features.&nbsp;It consist of horizontal readout planes made of perforated and segmented PCB's, interleaved by a cathode plane and surrounded by the Field cage. The detector takes advantage of the former Dual-Phase assembly and installation concept in the NP02 cryostat.&nbsp;</span></span></span></span></span><span><span><span><span><span style="color:black">The validation of the concept and the adopted technical solutions require&nbsp;a vigorous R&amp;D program. This is culminating in&nbsp;several tests of the full size detector elements, being performed at the CERN-NP.&nbsp;</span></span></span></span></span></p> <p><span><span><span><span><span style="color:black">In the seminar, the&nbsp;VD concept and its detector components will be presented together with the related technological issues. An important R&amp;D effort is presently pursued by several DUNE institutions:&nbsp;the first encouraging results will be reported.</span></span></span></span></span></p> Vertical Drift LAr-TPC for the DUNE Experiment: https://cern.zoom.us/j/68850690775?pwd=ak5JSlk0cWs4MENueDRtTnU5UHk5dz09
