Studies of time projection chambers using micro-pattern detectors for the DUNE experiment
Description
The discovery of neutrino oscillations highlighted that the neutrinos are massive, which is currently not explained by the Standard Model. Future neutrino oscillation experiments will mainly focus on measuring both the neutrino mass hierarchy and discovering a possible CP violation in the lepton sector. The DUNE experiment, which is treated in this thesis, proposes in particular to measure these two parameters. Several technological solutions based on TPCs for the DUNE experiment are discussed in this thesis. The operation of a dual-phase liquid argon TPC prototype, protoDUNE-DP, is described, as well as, the analysis of its data in order to characterize the stability and performances of this technology at a large scale. In addition, the study of a design for the SAND near detector of DUNE, involving resistive MicroMegas TPCs and a highly granular 3D scintillating detector, is studied. The adequation of the TPCs design with the DUNE beam and their impressive performances are demonstrated through numerical simulations. The neutron detection capabilities of the scintillating detector are established, and their beneficial impact on the neutrino energy reconstruction are highlighted. (author)
Abstract (French)
La decouverte des oscillations de neutrinos a permis de mettre en evidence le fait que les neutrinos possedent une masse, ce qui n'est actuellement pas explique par le Modele Standard. Les futures experiences d'oscillations de neutrinos vont se concentrer principalement sur la mesure de la hierarchie de masse des neutrinos ainsi que sur la possible decouverte de la violation de CP dans le secteur leptonique. L'experience DUNE qui est traitee dans cette these se propose notamment de mesurer ces deux parametres. Plusieurs solutions technologiques a base de TPCs pour l'experience DUNE sont discutees dans cette these. L'operation d'un prototype de TPC double-phase, protoDUNE-DP, y est decrite ainsi que l'analyse de ses donnees afin de caracteriser la stabilite et les performances de cette nouvelle technologie a grande echelle. En outre, l'etude d'un design pour un detecteur proche de DUNE, SAND, mettant en jeu des TPCs instrumentees avec des MicroMegas resistifs ainsi qu'un detecteur scintillant a haute granularite et a lecture 3D. L'adequation du design des TPCs avec le faisceau de DUNE y est etudiee ainsi que la caracterisation des performances des TPCs a l'aide de simulations numeriques. La capacite de detection des neutrons du detecteur scintillant est demontree, et son impact positif sur la reconstruction de l'energie des neutrinos est mise en exergue
