The Successful candidate will join the LPSC Neutrino team which has been participating since 2019 in the DUNE/LBNF project whose main objective is to measure two properties that remain to be discovered: the hierarchy of neutrino masses and the CP violation in the lepton sector. For this, a long baseline experiment will be built to propagate a beam of neutrinos produced at FermiLab through earth and detect them 1300 km away in an underground mine in South Dakota by 2030. The detection of neutrinos will be carried out using four very large (60m x 12m x 12m) liquid argon temporal projection chambers (LarTPC).
Detectors of this size require a very large R&D effort currently underway at CERN on the neutrino platform. France will participate via a TGIR in the construction of these detectors and is focusing on a new technology, the “vertical drift”. A large-scale prototype will be installed at CERN in 2022.

The successfull candidate will play a key role in the simulation and analysis of a liquid argon detector using this new technology. The aim will be to precisely determine the performance of the vertical drift technology on all the scientific objectives of the experiment.

The members of the LPSC Neutrino team involved in the DUNE project, four permanent staff and a doctoral student, participate in several aspects of this R&D such as the realization and operation of a cosmic detector for the CERN prototype, the instrumentation for precise measurements of the liquid argon level and consider other participation in scintillation study or high voltage. The LPSC will contribute to the data taking with the prototype at CERN and to their analysis. The study of neutrino-argon interactions, the reconstruction of traces, the effects of detectors and the sensitivities of the experiment to scientific objectives are activities which have started and will take an increasing part in the near future. The candidate will have a driving role within the team in this analysis and simulation effort in close connection with the working groups of the DUNE collaboration.


- The successful candidate must become familiar with the simulation of the DUNE experiment (LarSoft), make an inventory of what exists, is to be done or to be improved for the specific case of vertical drift .
- Participation in data taking at CERN and their analysis, and validation of the simulation.
- He / she will work on the reconstruction of traces (simulated and measured on the prototype) by participating in the adaptation of methods or by proposing new approaches.
- These different activities should lead to the expected sensitivity of the vertical drift to the different objectives of the experiment.


- PhD degree in physics with a maximum of 2 years of research experience after the PhD.
- Experience in particle detectors, Monte-Carlo simulation and data analysis.
- Ability to work in collaboration within the team as well as in an international environment.
- Autonomy and initiative to carry out research work

Work Context

The laboratoire de Physique Subatomique et de Cosmologie of Grenoble (LPSC) (http://lpsc.in2p3.fr) is a joint research unit associating the CNRS-IN2P3, the University of Grenoble Alpes (UGA) and the Grenoble INP school, for an average workforce of around 230 people. The recruited post-doctoral fellow will be assigned to the Neutrino research team of the LPSC composed of 7 permanent, 1 post-doctoral student and 2 doctoral students. The team is currently working on two projects: the measurement of coherent neutrino scattering at the ILL nuclear reactor and the Deep Underground Neutrino Experiment (DUNE). The post-doctoral fellow will work on the DUNE project in close collaboration with the other members of the team. He/she will have to interact within the international DUNE collaboration made up of more than a thousand members with an involvement of more than 30 countries and a participation of several French laboratories of CEA and IN2P3 (APC, IJCLab, IPNL, LAPP and LPSC).
-Frequent trips to CERN for activities on the prototype.
-Travel to the United States for collaboration meetings.
