A neuroscience research center with very high field MRI equipments has been opened in November 2006 by the CEA life science division. One of imaging systems will require a 11.75 T magnet 900 mm warm bore. Regarding large aperture and strength, this is real challenge when compared to largest ever built, it being developed within an ambitious R&D program, Iseult, focused on MRI. The conservative design principles are not readily applicable, other concepts taken from energy physics or fusion...
The Iseult system is a highly homogeneous 11.7 T superconducting magnet. This high field 900 mm warm bore coil will provide the main of Iseult/Inumac MRI system, dedicated to Neurospin center CEA life science division. cold mass structure magnet designed support and accurately locate central shielding coils. winding made 3.8 m length stacking 2 outer diameter double-pancakes. Under self load, axial compression reaches 8100 t. two coils are 4 short solenoids. assembly consists suspension...
AIRS is the infrared spectroscopic instrument of ARIEL: Atmospheric Remote‐sensing Infrared Exoplanet Large‐survey mission adopted in November 2020 as Cosmic Vision M4 ESA and planned to be launched 2029 by an Ariane 6 from Kourou toward a large amplitude orbit around L2 for 4-year mission. Within scientific payload, will perform transit spectroscopy over 1000 exoplanets complete statistical survey, including gas giants, Neptunes, super-Earths Earth-size planets wide range host stars.

AIRS is the infrared spectroscopic instrument of ARIEL: Atmospheric Remote‐sensing Infrared Exoplanet Large‐survey mission selected in March 2018 as Cosmic Vision M4 ESA and planned to be launched 2029 by an Ariane 6 from Kourou toward a large amplitude orbit around L2 for 4 year mission. Within scientific payload, will perform transit spectroscopy over 1000 exoplanets complete statistical survey, including gas giants, Neptunes, super-Earths Earth-size planets wide range host stars.

The Iseult project started in 2001 and is a collaborative effort involving CEA the University of Freiburg academics, Guerbet, Siemens Healthineers Bruker Biospin as industrial partners. One central aspect has been design by whole-body magnet 11.7T field strength with 90-cm wide bore. After nearly 20 years research development, prototyping, integration tests, first images have acquired this unique MRI scanner. Some key validation results are presented here.
CEA Saclay is working since 2008 on High Temperature Superconductor (HTS) developments for accelerator magnet application. Two dipole models were realized at Saclay: the EuCARD block and EuCARD2 cosine-theta magnet. The magnet, relying 12-mm REBCO tapes, was first step to demonstrate potential of type HTS ceramic tapes generate 5-T field. manufacturing completed in 2016, cold tests performed 2017. Magnet design process, as well have already been presented 2018. Since then, additional carried...
BINGO is a project aiming to set the grounds for large-scale bolometric neutrinoless double-beta-decay experiments capable of investigating effective Majorana neutrino mass at few meV level. It focuses on developing innovative technologies (a detector assembly, cryogenic photodetectors and active veto) achieve very low background index, order $10^{-5}$ counts/(keV kg yr) in region interest. The demonstrator, called MINI-BINGO, designed investigate promising isotopes $^{100}$Mo $^{130}$Te it...
Absolute Quantum Efficiency (QE) measurements are very demanding. To measure the QE of detectors from 0.8μm to 12.5μm a dedicated test bench has been built. The Quantix relies on an optical design ensuring uniform flat-field illumination detector. uniformity was measured with photodiodes built and calibrated at CEA/LETI. While performing measurements, photodiode is placed in vicinity detector incident flux. validated whose European Space Agency. In this paper, will be described details...
The fourth medium class ESA mission Atmospheric Remote-Sensing Infrared Exoplanet Large-survey also known as ARIEL is dedicated to the study of exoplanets. goal this characterize atmosphere exoplanets find out what they are made of, how form and evolve. satellite composed two instruments: AIRS, for Spectrometer, a Fine Guidance System (FGS) which used both monitor position near infrared spectrometer photometer. AIRS instrument channels; one covers spectral range 1.95 μm – 3.9 (called CH0)...
The program Astronomy European Infrared Detector (ASTEROID), funded by the Union through H2020 (under Grant Agreement n°730161), aims at enabling Europe to acquire technology and knowledge necessary manufacture 2k² high performance IR detectors. To reach these goals 9 detectors have been manufactured Lynred characterized Astrophysics Department of CEA. ASTEROID are 640×512 pixels arrays with a pixel pitch 15 μm. p-on-n technology, μm pitch, cut-off wavelength 2.1 In detector architecture,...

La question de la radicalisation a conduit à rechercher des profils psychologiques, traits personnalité, voire l’existence troubles mentaux, façon pouvoir prévenir les processus ou du moins traiter secondairement. Les diverses études menées depuis une vingtaine d’années montrent que sont nombreux, évoluent au fil années, et ne peuvent certainement pas se résumer un quelconque trouble psychique. Des typologies ont été établies, elles permettent d’intégrer analyse psychologique dans approche...
