Résultat scientifique

Une équipe de l’Iramis a développé, en collaboration avec des chercheurs de l’Institut Frédéric-Joliot, un dispositif microfluidique, couplé à une technique de spectrométrie de masse. Elle a ainsi pu multiplier par trente la sensibilité de l’analyse par rapport à l’état de l’art, comme en témoigne un spectre obtenu par ce procédé sur un dépôt de quelques femtomoles (10-15) d’un peptide modèle.

When the history-making Cassini spacecraft descended into Saturn's atmosphere for a fiery finale in September, two decades and two mission extensions after its launch, scientists at Leti could proudly say "mission accomplished". Leti and the Astrophysics Laboratory at CEA Saclay had designed, tested and fabricated infrared detectors for Cassini's Composite Infrared Spectrometer (CIRS). Spectrometers split light into different colors, like a glass prism, and CIRS was special because it was sensitive to invisible heat rays, or infrared light emitted by the planet, its rings and its moons.

Scientific result

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.
