The fibered LIBS (Laser-Induced Breakdown Spectroscopy) technique was tested for the first time in the vacuum chamber of a fusion machine by the CEA and CORIA (Complexe de Recherche Interprofessionnel en Aérothermochimie, Rouen) teams.
A high-power mock-up of an Ion Cyclotron Resonance Heating Travelling Wave Array antenna has been validated in the CEA/IRFM TITAN Testbed. Up to 2 MW/3s (Max Generator RF power) and 500kW/60s were achieved at 55.5 MHz. Electrical responses are as expected by modelling: the antenna is wide-band (10 MHz) and has a lower electric field than a conventional antenna (around 20 kV for 2 MW).
CEA has successfully passed the Preliminary Design Review of the port plug part of the equatorial ITER Wide Angle Viewing System.
This year, we celebrated the 10th anniversary of the "Theory Festival", organized since 2001 every other year in Aix-en-Provence. This international scientific event was created under the leadership of Jean Jacquinot, current scientific advisor to the ITER Director General Bernard Bigot.
Remote participation to fusion experiments will be used in the next years by scientists all over the world. On November 28th, for the first time, the Remote Experimentation Center (REC) in Rokkasho (Japan) took control of the WEST IRFM tokamak in Cadarache, located 9486 km away.
For the first time, the tritium/hydrogen isotopic ratio of a gas has been measured in a glove box, in the Tritium Labelling Laboratory (LMT) at CEA Saclay.  This measurement has been done with an optical Penning gauge routinely used for measuring the H2/D2/T2 fuel isotopic composition and He/D2 concentration in magnetic fusion devices such as JET, WEST and in the future in ITER.
A new infrared thermography system has been installed in the WEST tokamak to observe the thermal scene of the first wall and components in a wide-angle tangential view of the poloidal cross-section. 
The CEA inaugurated the WEST tokamak on April 6, 2018 in the presence of national and local elected officials, and institutional investors who funded it.
On December 12, 2017, the last JT-60SA toroidal field coil came out of the General Electric workshops (formerly Alstom) in Belfort. This important milestone brilliantly concludes the French contribution for the supply of 10 of the 20 main magnets of the superconducting tokamak being assembled in Japan.
The French Atomic and Alternative Energy Commission (CEA) and the Ministry of Science and Technology of the People's Republic of China (MOST) signed on November 23 and 24, 2017 in Beijing the creation of the Franco-Chinese Center on Energy Fusion (SIFFER, SIno-French Fusion Energy centeR).
The first large component of the ITER project's magnetic system has arrived at the Institute for Magnetic Fusion Research (IRFM), ready to be tested. This event is worthy of the limelight.
A new Infrared diagnostic has been developed by IRFM to study heat loads on the W monoblocs of the Divertor plasma facing units (PFU) with a very high spatial resolution @ 100µm. The objective is to study the effects of misalignments, mutual shadowing of the Divertor PFUs as well as the geometry (shaping) of the monoblocs.
The “René Pellat Memorial Festival Prize" aims to distinguish a young researcher for his/her significant work in plasma physics developed during the Festival de Théorie. Miss CHE received on July 6 this new price set up in 2017 from a CEA initiative.
The equatorial visible/infrared Wide Angle Viewing System (WAVS) is developped by CEA in a consortium with Ciemat (E) and Bertin Technologies (F). The design of port-plug components for this very complex diagnostic has been promoted by Fusion for Energy as the new reference model of the European Domestic Agency.
IRFM designed, manufactured and qualified some mock-ups for DEMO divertor developped in a EUROfusion project. These components use an innovative material which resisted up to 25 MW/m2 heat fluxes.
TINT, Thailand Institute of Nuclear Technology, represented by its Executive Director Nisamaneephong Pornthep and CEA / DRF represented by Maria Faury signed a collaboration agreement in the field of Magnetic Fusion Research.
On July 26th, 2016, the Japanese Institute QST (Quantum & Radiological  Science and Technology) organized in Naka (Ibaraki) a ceremony in honour of “constant progress of French contribution to the JT-60SA project”. This contribution is mainly composed of high technology elements, essentially manufactured in France and being installed in Japan.
The five Power Supplies built in Spain under CEA responsibility have been delivered to Japan for the JT-60SA tokamak. After a 42 day long shipping and a thorough inspection of boxes thanks to shake detector sensors, the Power Supply components could be transferred to Japanese at the Yokohoma port.
The René Pellat prize, named after the great scientist who was once chairman for CNRS (French Scientific Research Council) and High Commissioner for CEA (French Agency for Atomic Energy), is awarded annually by the Plasma division of the French Physical Society.
February 12, 2016, at the Cold Test Facility at CEA-Saclay, the first toroidal field coil of JT-60SA - manufactured by General Electric/Alstom under the supervision of the CEA - became the first of 28 superconducting coils of JT-60SA – already manufactured or still being processing - to reach the superconducting state.
This article published in Nature Physics 12, 14-17 (2016) by D. Mazon, C. Fenzi and R. Sabot, is related with the problem of sustaining and measuring temperature in fusion plasmas. This challenging task requires different heating systems and diagnostic tools. Information on the spatial distribution of temperature is one of the key elements for improving and controlling plasma performance.
The two stainless steel rings constituting the housing for the conductor winding are now assembled and positioned inside the vacuum vessel at their nominal position.  
The first of the 18 JT-60SA Toroïdal Field coil was delivered at CEA Saclay on December 17th 2015. There, it will be tested before to be shipped to Japan. This coil, manufactured by Alstom/General Electric at Belfort France under CEA responsibility, is the largest ever built.
A training session for Sycomore was organized via videoconference on the 15th-16th  December 2015 for our partners involved in DEMO studies in Europe. This code will allow to design the next post-ITER reactor generation and perform sensitivity analyses of the machine’s performances on the design parameters and assumptions.  
With the installation and commissioning of two main equipment finalized on October 15, 2015 in CEA premises, MIFI (Magnet Infrastructure Facilities for ITER) is fully operational. Recently, a 3 axis Computer Numerical Control (CNC) milling machine was delivered and installed, and a complete High Voltage Test bench was commissioned.  
WEST H-mode-like configuration has been investigated using SOLEDGE2D-EIRENE simulation tool. Two cases at high plasma density have been studied : the first one in pure deuterium discharge and the second one with Nitrogen seeding. These simulations will provide guidance for the preparation of WEST operation.
Turbulence is a major issue in tokamaks, in particular as it drives energy from the core of the plasma to the edge of the plasma. This undesired energy transport is one of the elements which account for the difficulty of maintaining fusion-favourable conditions in the heart of tokamaks. The introduction of a specific perturbation (EGAM) could contribute to reduce turbulence.
A Broader Approach & JT60SA Press conference was held in Saclay on 14th November 2014. Thanks to this event, different aspects were highlighted: The different projects undertaken in Japan in support of ITER and an update on their actual status. The CEA and the French & European companies’ contribution  
The coupling of the system code SYCOMORE developed by the IRFM with the URANIE platform of the DEN has achieved a design optimization of the future fusion reactor DEMO using a genetic algorithm. The objective was to find the parameters of the smallest reactor producing at least 500 MW of electricity with long enough pulse duration.
