Offer Description
The student will have the possibility of joining the DUNE effort at LP2IB and to participate to the software development related to the improvement of the energy reconstruction. He/She will participate to the tests of the module-0 at CERN, based on the vertical drift technology, in 2025 and directly test and tune on real data the carried out developments.
Part of the thesis work will be carried out at University of Chicago, which is deeply involved in the project since the very beginning. The Chicago group is mostly involved in the horizontal drift detector and they have a longstanding experience in the tools development for the reconstruction of such a detector. Their expertise would be beneficial to port the tools to the vertical drift detector and exploit the most the properties of the liquid argon TPC.
The neutrino energy reconstruction is a primordial piece of information for all oscillation analyses. To perform a correct momentum balance and infer the neutrino energy, the different particles have to be correctly identified, which is not a trivial task in particular when they are part of hadronic showers. The same sort of difficulty arises for electron neutrinos in the reconstruction of electromagnetic showers.
Identification algorithms have been studied for years and new techniques as machine learning are being developed, however all those fancy methods relies on the very basic information which is the charge reconstructed on each channel. The detector response was modeled for the so called horizontal drift detector based on wires readout and all the developed tools were ported on the software for the analysis of the module based on the vertical drift technology. Nonetheless the difference in the readout and in the electronics needs specifics tunings and first tests showed that a better definition of the reconstructed hits and their reconstruction could result in a more precise neutrino energy reconstruction.
The successful candidate will join the LP2I Bordeaux group, which joined the DUNE experiment in January 2023, and since then worked on two different aspects: on the hardware side on the testing and production of the vertical drift electronics, and on the software side on the vertical drift reconstruction optimization.
