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 »

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 »

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 »

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 »
