SBT has developed a library to simulate cryogenic refrigerators, from hot compression up to the cryodistribution. This library allows to better understand the behavior of this machines, but also to optimize thanks to model-based-design approaches Each component of the library is described by ... More »

The cryogenic plant of the tokamak JT60-SA has successfully pass one of the most demanding acceptance tests. September 27, 2016, the facility was given to nominal mode with all compressors at full capacity; a series of high power pulses were applied to all cryogenic loops in order to reproduce ... More »

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. ARTEMIS (Bolometers Architecture for Large Field of View Ground-Based ... More »
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.   How the results ... More »

A new photonic camera has been developed in the framework of the ArTéMis project (Bolometers architecture for large field of view ground based telescopes in the sub-millimeter). This camera scans the sky in the sub-millimeter range at simultaneously three different wavelengths, namely 200, ... More »

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 meeting brought together some forty European and Japanese experts in charge of coordination and components for future tokamak JT-60SA which ... More »
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. The SBT has ... More »
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. CEA has the ... More »

Gaze at the Eagle Nebula, close to the centre of our Galaxy. Star forming regions can be spotted in this picture (centre and left portion). According to astrophysicists, hundreds of stars are born here. This picture was taken in April 2010 by two of the instruments on board the Herschel satellite ... More »

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. the time it takes for ... More »
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. Turbulent ... More »

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. We have developped and validated a innovative method of pressure regulation that guarantees this operational ... More »
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. Their free surfaces may be subject to shape instabilities whenever ... More »
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. An experimental program has been devised, aimed at reducing the temperature by means of an ingenious ... More »

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. In collaboration ... More »
