Description

The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino-oscillation experiment aiming at measuring CP-violating phase and neutrino mass ordering. The experiment takes place in the United States, from Fermilab to SURF in South Dakota. The far detector is 1.5 km underground and consists of four 17-kt modules based on Liquid Argon Time Projection Chamber (LArTPC) technology. During the DUNE first phase of operation, two LArTPC modules with different designs will be used as the far detector.In order to assess the performances of these LArTPC designs, to practice and validate the construction sequence, intermediate-scales prototypes (protoDUNE) have been built and operated at the CERN Neutrino Platform with cosmic and beam data.During 2018-2020, two protoDUNEs took data : the ‘single-phase’ which uses wires to collect the charge signal, and the ‘dual-phase’ where the charges are amplified before collection. Following the outcome of this first data-taking campaign, two new protoDUNEs are about to collect data. The horizontal-drift is testing the final designs of the former single-phase technology, while the ‘vertical-drift’ prototype explores a new concept that combines the strength of the single- and dual-phase technologies.This seminar will discuss about the technologies and the performances of the four protoDUNEs, explain the motivation of the new vertical-drift concept and present the physics analyses performed.
