The JET machine area is a hive of activity as the Culham Centre for Fusion Energy (CCFE) prepares the facility on behalf of EUROfusion for its next run of experiments later in 2015.

The shutdown period is an opportunity for engineers to tune up key systems on JET and to install new components to improve the tokamak's performance. This time round, the focus is on plasma fuelling and heating systems. The high frequency pellet injector, which propels frozen deuterium fuel into the JET plasma, is being optimized and repositioned to achieve more reliable operation. A refurbished antenna—the ion cyclotron resonance heating system, which produces radiowaves that resonate with the plasma particles and heat them up—will also be plugged in. JET's antenna is similar to the one that the next-step ITER Tokamak will use. Bringing it back online will mean that experiments can simulate ITER conditions more accurately, and has the added advantage of helping to flush out impurities from the core of the plasma.

European fusion researchers are keen to see how the 2014 JET tests have left their mark on the machine. The shutdown is enabling CCFE's team of remote handling engineers to remove sample tiles from the interior of JET so their condition can be analyzed. Inspecting the tiles will yield valuable information about how the beryllium and tungsten wall lining is being affected by its close proximity to the plasma (another hot topic for ITER). And a remote-controlled vacuum cleaner has been inside JET collecting dust which can also give pointers on the interaction between the plasma and the wall materials.

In a similar vein, a new high-resolution camera has just been taken into the JET chamber to photograph the tiles in the divertor region. In this area, as the name suggests, impurities and waste material are diverted out of the plasma, and the tungsten surfaces of the divertor are exposed to intense heat as a result. The photographic survey is giving scientists the most detailed pictures yet of the condition of this area of the machine.

The ITER Business Forum 2015 (IBF/15) will take place in Marseille, France from 25 to 27 March 2015.

Already, 256 participants from 135 companies have registered to participate.

IBF/15 is a unique occasion for companies to approach the ITER Project and to investigate possibilities for involvement or partnership around upcoming tender offers.

Key project actors will present the status of systems. Twelve thematic workshops with presentations will be given by the ITER Organization, the procurement agencies for ITER—the Domestic Agencies—and key suppliers.

Visit the IBF/15 website for registration information.

The JET and Medium-Size Tokamaks General Planning Meeting was held in January in Lausanne at the Olympic Museum. The conference was a major step towards the internationalization of the TCV tokamak at EPFL (the Swiss Federal Institute of Technology in Lausanne).   The EUROfusion Consortium is the umbrella organization of all fusion research laboratories in Europe including Switzerland. Tasked with building the roadmap to ITER and DEMO, the prototype of a fusion commercial reactor, it provides the work platform for exploiting the Joint European Torus (JET) in the UK, sometimes referred to as "little ITER." EPFL's TCV tokamak carries out important experimental work in fusion, focusing on different plasma confinements and shapes.    The Planning Meeting, organized by the Center for Research in Plasma Physics (CRPP), which runs the TCV, focused on proposals for experiments aligned with the EUROfusion roadmap and that could be performed in 2015 on the roadmap's dedicated devices: JET, ASDEX Upgrade and EPFL's TCV. Scientists presented their views of a comprehensive experimental strategy, which was discussed by the almost 150 senior scientists attending the conference.   The selected experiments will be performed on EUROfusion's different devices by international groups of physicists. The plan calls for the TCV to be used for almost two months in 2015 and early 2016, while it will also continue to operate for EPFL's own research goals, which are generally also aligned with the ITER roadmap.   The conference included a visit of the TCV, followed by a reception at the CRPP's site.   Read the full article on the EPFL website.
