Résumé

Alain Benoît, physicist at the Néel Institute in Grenoble, received the 2012 CNRS innovation medal. This is an opportunity to describe his research in cryogenic development.
As a specialist in the physics of solids at very low temperatures he has developed technological processes that allow detection instruments used in space missions to be cooled in order to increase their performance. The closer you get to the absolute zero limit, the more effective space instruments are. Alain Benoit has developed an exceptional cooling device, the dilution cryostat, which is now built into many instruments. The HFI camera on the Planck cosmological satellite, for example, holds the cold record temperature for a space instrument, with a cryostat cooled down for more than two years to -273.05°C. His inventions are protected by three patents.
