The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
September 2021, the 11.7 Tesla MRI of the Iseult project, the most powerful in the world for human imaging, has just unveiled its first images.
Researchers from the LSI (CEA-Iramis) and their partners are showing that it is possible to accelerate electrons more efficiently by laser-plasma interaction, using a progressive rotation of the laser wave front.
Researchers from the CEA-Joliot (I2BC) and their partners have deciphered for the first time the quantum process of energy dissipation in aggregates of natural flower carotenoids. This fundamental biological mechanism could inspire the design of photovoltaic materials capable of supplying two electrons for every photon.
After a decade of R&D, the Irfu delivered 74 new electronic boards produced by the company FEDD to CERN in July 2021, for use with the ATLAS electromagnetic calorimeter. These boards will be used to handle the increasing data flow that will be produced by the LHC as soon as it restarts in February 2022.
The H.E.S.S. collaboration, which includes physicists from Irfu, has made ground-based observations in Namibia of gamma-ray sources detected by the Fermi space observatory that remain unidentified, otherwise known as Unidentified Fermi-LAT Objects (UFOs). These were suspected to be possible indicators of dark matters halos shining at very high energies, but the verdict now shows that UFOs are not actually these kinds of subhalos!
For the first time, a team from Biam is showing the transcription of DNA into messenger RNA in the cells of young plants, in real time and with an unprecedented resolution. This exceptional live work reveals highly useful information on the biological mechanisms linked to the plant’s response to its environment.
A mock-up of a high-power travelling wave antenna has been successfully tested at the IRFM. This new family of antennas operates at a lower voltage than current antennas, requires fewer adjustments, and can be deployed inside the tokamak. In short, it is better adapted to the hostile environment of a tokamak!
A team from the NeuroSpin (CEA-Joliot), in collaboration with Inserm (Tours), has published the first anatomical atlas of the human brain stem using mesoscopic resolution ultra-high field MRI. This atlas, freely accessible as a wiki, will be used in particular by neuroanatomists and neurosurgeons to help them in their procedures.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
