Job Description
Thesis Subject
The T0TEM (0νββ TES Experiment using ¹⁰⁰Mo) project focuses on the development of Li₂MoO₄ scintillating bolometers for the search for neutrinoless double-beta decay (0νββ). The objective is to reduce by one order of magnitude the background arising from surface radioactivity of the crystals and from the pile-up of two-neutrino double-beta decay (2νββ) events. The PhD project focuses on characterizing the scintillation properties of Li₂MoO₄ crystals and optimizing their geometry through optical simulations and experimental measurements on dedicated test benches. Part of the work will also involve sensitivity studies for 0νββ, 2νββ, and other exotic ββ decay modes.
Your Work Environment
The work will involve numerical simulations based on the GEANT4 software package, including optical photon transport simulations in the crystals and simulations of the detector response to ββ decays and background events, performed on a computing grid. Measurements of the optical properties of the crystals (light yield, emission and absorption spectra, refractive index, and surface effects) will be carried out on dedicated test benches at LP2iB and IJCLab (France). Additional measurements are planned at the National Laboratory of Gran Sasso (Italy).
Constraints and risks
Minimal risks associated with software development and data analysis, including code management and version control, as well as data storage, sharing, and backup. The project also includes several missions in the underground environment of the National Laboratory of Gran Sasso.
