The detection of ionising particles is the technology par excellence of subatomic physics and Subatech, like most of the IN2P3 laboratories, masters the technologies of gas, semiconductor and scintillation detectors. The realization of detection systems for international collaborations has enabled Subatech to acquire know-how in the integration of detection systems within large-scale multi-detector experiments, and all associated services: high and low voltage power supply, cooling, remote control, etc. The management of interfaces in these experimental projects and a quality approach at the level of an industrial production are requirements that are perfectly mastered by Subatech. The ALICE, Double Chooz, SoLiD, KM3NeT, JUNO, e-SHAPE projects make use of this specific Subatech know-how.
Among the new detection techniques, Subatech has a mastery, unique in France and rare in the world, of the technology of detectors based on liquid xenon and the auxiliary elements to these detectors such as the purification system, cooling, and the design and production of the adapted reading electronics. These are the Xenon and XEMIS projects. We participate in R&D for the design of new detection techniques for dark matter and rare decay (Xenon, SPHERE and DAMIC-M projects) and for the detection of neutrinos (future LiquidO project).
The radiochemistry laboratory is a unique facility at regional and national level for the study of materials for nuclear energy, the study of radionuclides in the environment and for health, the effects of radiation (radiolysis) and through its mastery of ultra-trace techniques.
Within the framework of the IRMA master-project, we have developed know-how in ion beam analysis (IBA) and analysis by PIGE and PIXE techniques.
The development of software for theoretical modelling in hadronics physics, reconstruction of raw data, detector simulation and physics analysis, as well as the analysis of large amounts of data and the deployment of distributed computing within the framework of the LCG project (ALICE-Tier2 project) are technologies that are present at Subatech.
These activities attract external actors to valorise our results, thus contributing to the transfer of the knowledge produced in the laboratory in a form that can be used for the production of goods or services.
