Postdoctorate : TINY experiment for neutrinoless double beta decay search H/F
Cadre
24
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.
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.
Profile of the candidate
For the application, the following documents are required
- a CV, including the complete list of publications;
- up to 3 selected publications that particularly characterize the applicant's profile;
- a copy of a valid ID document;
- a motivation letter.
Additionally, the applicants are free to indicate the names and contact information of up to two reference persons, which will be asked to provide a reference letter.

The CEA is the French Alternative Energies and Atomic Energy Commission ("Commissariat à l'énergie atomique et aux énergies alternatives"). It is a public body established in October 1945 by General de Gaulle. A leader in research, development and innovation, the CEA mission statement has two main objectives: To become the leading technological research organization in Europe and to ensure that the nuclear deterrent remains effective in the future.
The CEA is active in four main areas: low-carbon energies, defense and security, information technologies and health technologies. In each of these fields, the CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research.
The civilian programs of the CEA received 49% of their funding from the French government, and 30% from external sources (partner companies and the European Union).
The CEA had a budget of 4,3 billion euros.
The CEA is based in ten research centers in France, each specializing in specific fields. The laboratories are located in the Paris region, the Rhône-Alpes, the Rhône valley, the Provence-Alpes-Côte d'Azur region, Aquitaine, Central France and Burgundy. The CEA benefits from the strong regional identities of these laboratories and the partnerships forged with other research centers, local authorities and universities.
