Actualité
A dipole magnet, built by a European collaboration involving IRFU from high-temperature superconductors, has produced a 4.5 tesla magnetic field, which is one tesla higher than previous prototypes. Once inserted in a Niobium-Tin dipole magnet, the whole system will produce an 18 T field.
In collaboration with scientists from the Frédéric-Joliot Institute, a team from IRAMIS has developed a microfluidic device coupled with a mass spectrometry technique. The scientists were able to multiply the analysis sensitivity by thirty compared to the current state of the art, as shown by a spectrum obtained using this process on a deposit of a model peptide of a few femtomoles (10-15).
The new-generation liquid argon detector used in the WA105 experiment at CERN has collected its first signals. This prototype is used in preparation of the Deep Underground Neutrino Experiment (DUNE) for neutrino observations on a mass scale, which is due to start in 2026 in the USA. This research involving IRFU aims, in particular, to shed light on the origin of matter and antimatter.
Designed to equip the FRESCA2 testing station at CERN (Facility for the Reception of Superconducting Cables), the niobium-tin dipole magnet of the same name has reached a record 13.3 T magnetic field for a 100 mm aperture. It was designed and developed as part of a collaboration between IRFU and CERN. The objective is a magnetic-field homogeneity 1% over a length of 540 mm.
Can a living organism be obliged to take something other than its regular route for the synthesis of the molecules it needs to live and multiply? A team from the François Jacob Institute of Biology did just that, getting bacteria to assimilate CO2 in a new way.
Le laboratoire de l‘Iramis spécialisé dans les archéomatériaux se lance dans une nouvelle aventure : la restauration et la protection des objets métalliques du patrimoine. Comment partager l’expérience acquise pour étudier le stockage des déchets nucléaires avec les restaurateurs, experts eux aussi de la corrosion sur le long terme ?
Thanks to the ALMA European interferometer in Chile, an international team involving IRFU has detected ionized CH+ molecules in distant galaxies for the first time. Their observations reveal the unsuspected existence of large turbulent reservoirs of gas surrounding these young galaxies. The findings explain the persistently high star formation rate observed in galaxies known as "starburst galaxies".
En France, le CEA et le CNRS ont joué un rôle de premier plan dans la conception et la construction de l’accélérateur supraconducteur à électrons X FEL, au cœur de cette nouvelle infrastructure de recherche internationale inauguré à Hambourg (Allemagne) le 1er septembre 2017
Through the study of model systems, physicists from IRAMIS are gaining a deeper understanding of the mechanisms involved in the irradiation of a crystalline surface with "swift" ions. Ion beams can be produced by small accelerators and make it possible to shape surfaces on the atomic scale, including high-quality incisions or bends in a monoatomic layer of molybdenum disulfide (MoS2) or graphene.
For the first time, IRAMIS researchers have isolated complex ion pairs in the gas phase and were able to characterize them using UV and infrared spectroscopy. This original experimental approach will deepen the scientists' understanding of extremely diverse physicochemical processes in media as varied as biological cells and batteries.
