Description de l'offre

Subject of research :

The TINY (Two Isotopes for Neutrinoless double beta deca

Y 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.

Profil du candidat

Profile of the candidate :

* A PhD degree or an equivalent certification in particle physics or a closely-related discipline, to be obtained at latest by November 31, 2026.

* The ideal candidate should have experience in some of the following fields: millikelvin cryogenics, bolometric detectors, particle detectors, signal processing.

For the application, the following documents are required :
