Lionel Duband and his team were awarded the 2015 William E. Gifford Award by the Cryogenic Society of America (CSA). This prize rewards the team working on project ARTEMIS within INAC's Low Temperatures Department.
Summary of the highlight A small cryo-refrigerator dedicated to space missions reached temperatures lower than 4.2K (liquid helium) in our laboratory for the first time. This is the world record using helium 4 and some improvements are still expected with helium 3.
Born in 1967, Dr  Hab. Yves Samson was appointed director of Inac on October 1st, 2013.

The 17th meeting of technical coordination for the proposed superconducting tokamak JT-60SA was held in Grenoble in the INAC on 28 and 29 May 2013.
The distribution of cold power in cryogenic systems is becoming increasingly important, in particular because of the replacement of cryogen baths by mechanical cryocoolers which are local cold sources. Two-phase systems (heat pipes) are good candidates to address this new problem.
JT-60SA is the future tokamak of the Japan Atomic Energy Agency (JAEA). Superconductive magnets will be used to confine the plasma. The fusion reactor is jointly constructed through the Broader Approach Agreement involving Europe and Japan and it shall be in operation in 2016.

In collaboration with SPrAM, SBT has developed a temperature sensor based on fluorescent nanocrystals and optical fiber for temperature measurements in the range 4-40 K.   This type of sensor is based on the fluorescence decay of nanocrystals. The decay time, i.e.
In collaboration with Institut Néel, ENS Lyon, LEGI and IRAMIS, an apparatus was developed at SBT for the study of turbulence in superfluid helium. Our measurements show that the mechanism of energy transfer follows the same Kolmogorov law as do the classical viscous fluids.

SBT has a refrigerator called the “400W@1.8K” test facility. One of the challenges facing this type of machine is to ensure stable operation under extreme thermal perturbations.
In our magnetic levitation facility OLGA, in a low magnetic field, we have observed a beautiful ferrofluid behaviour of liquid oxygen, close to its critical point.   Ferrofluids are liquids loaded with magnetic colloids.
High-frequency pulse tube technology (30 ~ 50 Hz) meets space vibration and reliability requirements but, up until now, was restricted to temperatures greater than 35 K.

The main aim of the ITER fusion process is to generate 500 MW of heat power for a period of several minutes, from a 50 MW power input source. The indispensable condition: "proper" cooling of several tens of kilometres of superconducting windings that confine the plasma.
