Postdoctorate : TINY experiment for neutrinoless double beta decay search H/F

Description de l'offre
Subject of research :
The TINY (Two Isotopes for Neutrinoless double beta decaY search) experiment aims to investigate neutrinoless double beta decay (0n2b) using the Zr-96 and Nd-150 isotopes. Both of them possess the crucial advantage of very high transition energy for the 0n2b process, which would allow the experimenters to obtain a higher sensitivity to the effective Majorana mass compared to other isotope candidates. TINY project is focused on the development of a “source=detector” technology for these two isotopes. Currently, R&D phase is going on, with a dedicated cryogenic facility installed in CEA. The successful R&D would provide technology for Zr- and Nd- -based bolometric detectors with high performance, which will be measured in the TINY pilot experiment. It will consist of a few kg scale underground demonstrator and will be able to set the best limits worldwide on the 0n2b half-lives for both Zr and Nd isotopes thanks to high efficiency and energy resolution.
Description of the offer :
The successful candidate is expected to take part in several of these activities for TINY: detectors design and operation; sensors design and testing ; data analysis of bolometric detectors, sensitivity evaluation for 0n2b decay experiment. He/she is expected to work in the DBD group of DPhP, and take care of organisation/management of cryogenic runs, both in dedicated facility in CEA and in an underground laboratory.
