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.
Scientists at IRFM are studying the issue of Tungsten atom transport. This material that covers the walls of the tokamak vacuum chamber should not contaminate the plasma. Its accumulation in the plasma core can cause significant radiation losses often observed on the European tokamak JET and on Asdex-Upgrade in Germany. On the WEST tokamak, the rarity of this type of event has been explained.
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. 
On the 18th of December 2017 current was raised in the divertor coils and the very first X-point plasma was obtained in the WEST tokamak.
A complex system of Langmuir probes was designed and manufactured for the WEST divertor for local measurement of plasma flux to target. The delivery of the probes at IRFM - an in-kind procurement of the IPP-Prague to the WEST project - is the result of a long lasting and a very productive collaboration between the two institutes.
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.
The ITER Organization and the French Alternative Energies and Atomic Energy Commission (CEA) have entered into a five-year collaboration to operate a new facility that will test the assembly of the ITER magnet components.   The ITER superconducting magnets form the core of the machine.
