At least 100 miniature cameras will be installed inside the ºÚÁÏÉçapp machine to act as the eyes for operators charged with machine maintenance.

Some of them will give a wide-angle view of the inside of the machine; others will be embedded on the robotic arms used for repairs. By receiving live image from the cameras, engineers hundreds of metres away will be able to operate maintenance and repair equipment with extreme accuracy.

The European Domestic Agency has been working with Oxford Technologies Limited (OTL) to develop and validate the different subsystems of the miniature cameras, which will have to operate within severe space constraints and often in an environment exposed to radiation. Subsystems developed by ISAE, France (image sensors); CEA, France (illumination system); and Jean Monnet University Saint Etienne, France (optic system) have been successfully tested over the past year at Belgium's SCK-CEN facility where they were exposed to different levels of gamma radiation.

The next step will be to develop a camera prototype.

To predict the impact of removing exhaust heat from the ºÚÁÏÉçapp Tokamak, researchers are calling on the Titan supercomputer at the Oak Ridge Leadership Computing Facility in the US.

Using the 27-petaflop behemoth, researchers based at Princeton Plasma Physics Laboratory (PPPL) are simulating the area where the plasma edge meets the divertor—the material structure engineered to remove exhaust heat from the vacuum vessel. Specifically, the team has evaluated the heat-flux width at the divertor, or the width of the material surface that might sustain the highest heat load.

Because the divertor directly faces the exhaust flow, it is bombarded with hot particles driven by electromagnetic fluctuations. In ºÚÁÏÉçapp, in order to withstand the highest surface heat load, the divertor will be made of the toughest element on Earth: tungsten.

"You don't want to start and stop ºÚÁÏÉçapp too often to replace this divertor material, so it has to be able to withstand the heat load," team leader C.S. Chang reports. "Ideally, we want the hot exhaust particles to hit the surface in a much wider area so that it's not damaged."

Based on simulations made possible by Titan's supercomputing capacity, Chang's team predicts that in ºÚÁÏÉçapp, due to the size of the plasma, edge plasma turbulence may spread heat across a larger area of the divertor surface and significantly increase the heat-flux width relative to current smaller-scale fusion devices.

At the Swiss Plasma Center in Lausanne, Switzerland, the TCV tokamak was recently shut down for an upgrade of its Thomson scattering diagnostic. The operation was successful: shortly after commissioning the first measurements demonstrated greatly enhanced spatial and spectral resolution for the temperature and density profile measurements of TCV plasmas.

TCV is a variable configuration tokamak with highly specialized capabilities (plasma shaping, versatile electron cyclotron heating, measurement, control systems) for the exploration of the physics of magnetically confined plasmas.

Under contract with the European Domestic Agency, a team of experts has been working for more than a year to identify key technologies to perform the cutting and welding operations that will be required during the change-out of ºÚÁÏÉçapp divertor cassettes.

The technical constraints are enormous—the work (both cutting and welding) will have to be performed remotely, the operational space is severely limited, and no lubricant can be applied as ºÚÁÏÉçapp is a nuclear environment.

Experts from Assystem UK and the UKAEA robotics development laboratory RACE (for Remote Applications in Challenging Environments) have identified candidate techniques; now trials are underway and the search is on for the best tools to do the work remotely.

The steel, the pipes, the tangle of cables and wires ... to sum it looks confusingly technological—but to others it's inspiring!

UK artist Sarah Moncrieff specialises in urban scenes and industrial interiors. She first heard of JET, the European fusion research experiment hosted at the Culham Centre for Fusion Energy (CCFE), via a friend who works at the site.

"He thought, quite accurately, that I would be interested in it as a subject for my painting. What I hadn't anticipated was how much I would become interested in the work that is done at Culham. The work is fascinating and the sense of seeing something at the forefront of scientific progress was thrilling for me. I know that excitement informed my paintings."

Sarah's paintings of JET were recently exposed at an on-site Open Day, to popular acclaim. You can see more of Sarah's work on her .

After celebrating its First Plasma in December 2016, the WEST tokamak (for W Environment in Steady-state Tokamak) was reopened for the installation of two modified LHCD antennas for plasma heating (through lower hybrid current drive), then plasma operations restarted in April 2017.

Although plasma breakdown was routinely achieved, the ramping up of the plasma current was found to be difficult due to induced currents in the passive structures that have been introduced inside the vacuum vessel to produce the divertor configuration.

In effect, the WEST test platform is a modification of the Tore Supra tokamak at the Institute for Magnetic Research (CEA Cadarache, France) that introduces an actively cooled tungsten divertor. The machine has been considerably altered, with a "welcoming structure" for the new divertor, new in-vessel coils, new diagnostics, and adaptations to the heating, fuelling and cooling systems.

The vessel has been reopened to address stray magnetic field compensation through modification of the divertor baffle and a reduction in its electric conductivity to limit induced current. Experiments are expected to resume by the end of June.

For fusion to generate substantial energy, the ultra-hot plasma that fuels fusion reactions must remain stable and kept from cooling. Researchers have recently shown lithium, a soft, silver-white metal, to be effective in both respects during path-setting US-Chinese experiments on the Experimental Advanced Superconducting Tokamak (EAST) in Hefei, China.

Seven US researchers traveled to EAST in December, 2016, to participate in the experiments. They deployed lithium in the Chinese tokamak in three different ways: through a lithium powder injector, a lithium granule injector, and a flowing liquid lithium limiter (FLiLi) that delivered the element in liquid form to the edge of EAST plasmas. Good results were shown by all three techniques.

Leading the US collaboration is the US Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), together with co-principal investigators Los Alamos and Oak Ridge National Laboratories, with Johns Hopkins University, the University of Illinois at Urbana-Champaign, the University of Tennessee-Knoxville, and the Massachusetts Institute of Technology. Scientists from General Atomics also participate via a separate grant.

Lithium compounds improve plasma performance in fusion devices just as well as pure lithium does, a team of physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) has found.

The research was conducted by former Princeton University physics graduate student Matt Lucia under the guidance of Robert Kaita, principal research physicist at PPPL and one of Lucia's thesis advisors, as well as the team of scientists working on a machine known as the Lithium Tokamak Experiment (LTX).

Lucia used a new device known as the materials analysis and particle probe (MAPP), invented at the University of Illinois at Urbana-Champaign and installed on LTX. The MAPP system lets scientists withdraw samples into a chamber connected to LTX and study them without compromising LTX's vacuum environment. MAPP lets scientists analyze how tokamak plasmas affect a material immediately after the experiment ends. In the past, scientists could only study samples after the machine had been shut down for maintenance; at that point, the vacuum had been broken and the samples had been exposed to many experiments, as well as to air.

Lucia used the evaporation technique to coat a piece of metal with lithium, and then used MAPP to expose the metal to plasma within LTX. As he expected, Lucia observed lithium oxide, which forms when lithium reacts with residual oxygen in LTX's vacuum chamber. He was surprised, however, to find that the compound was just as capable of absorbing deuterium as pure lithium was.

"Matt discovered that even after the lithium coating was allowed to sit on the plasma-facing components within LTX and oxidize, it still was able to bind hydrogen," said Kaita.

Lucia's results are the first direct evidence that lithium oxide forms on tokamak walls and that it retains hydrogen isotopes as well as pure lithium does. They support the observation that lithium oxide can form on both graphite, like the tiles in NSTX, and on metal, and improve plasma performance.

In the context of its to the realization of fusion electricity , the European Consortium for the Development of Fusion Energy, has identified a number of crucial technical challenges that must be addressed through advanced research.

One of these is finding a viable solution for the heat exhaust in a future fusion reactor, considering that the divertor strategy planned for ºÚÁÏÉçapp cannot be extrapolated to a larger, steady-state facility.

Late 2015, EUROfusion called for proposals on plasma exhaust projects, which an independent panel of experts evaluated. The call, termed Plasma Exhaust (PEX) Assessment, received ten proposals that covered conventional and alternative divertors, as well as conventional materials and plasma-facing units as well as advanced materials.

EUROfusion selected six projects for receiving support. These include: ASDEX Upgrade at the Max Planck Institute of Plasma Physics, Garching (Germany); Forschungszentrum Jülich (Germany); Jozef Stefan Institute (Slovenia); MAST-Upgrade, (United Kingdom); TCV at the Swiss Plasma Center (Switzerland); and WEST at CEA (France).

Scientists now have a better understanding of the factors leading to steel degradation and of the ways to improve the design and development of key components, such as the ºÚÁÏÉçapp breeding blankets—where tritium fuel will be produced from the interaction of fusion neutrons with lithium.

In a unique test facility at the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) in Brasimone, candidate steels were exposed to liquid lithium in order to measure degradation (corrosion and/or erosion) over time.

Two types of reduced activation ferritic martensitic (RAFM) steels under consideration for fusion applications—EUROFER97 and F82H—were tested at ENEA's LiFus6, built for the project (IFMIF will carry out testing and qualification of advanced materials under conditions similar to those of a future fusion power plant/EVEDA is advancing the engineering validation of key IFMIF components and systems).

IFMIF/EVEDA is developed jointly by Europe and Japan in the framework of the agreement, which covers fusion R&D activities that are complementary to ºÚÁÏÉçapp and the next-stage device DEMO.

Following an initial run at the Wendelstein 7-X stellarator that lasted from December 2015 to March 2016, a shutdown phase ensued to equip the machine for an operational campaign with longer discharges and higher heating power.

As part of tasks to prepare for the next phase, programmed to start this summer, technicians have installed or adapted 8,000 graphite tiles on the inner wall of the plasma vessel, replaced the limiter with a test divertor, and installed cooling structures such as pipes and shields.

Culham's new tokamak is to receive funding to tackle one of the hottest issues in fusion energy research—plasma exhaust.

, the European consortium for fusion R&D, has approved the first phase of its contribution to a £21-million program of enhancements to MAST Upgrade, which is only months away from its first operations. Funding for the enhancements, which will be phased from now to 2022, will come jointly from EUROfusion and the UK's Engineering and Physical Sciences Research Council.

The controlled exhaust of power and particles from a very hot tokamak fusion plasma, through the divertor area of the machine, is arguably the biggest challenge facing a future fusion power plant. The extreme power loadings (>10 megawatts per square metre—higher than that on a spacecraft re-entering Earth's atmosphere) in a conventional divertor will require regular replacement of reactor components and adversely affect the economics and cost of electricity. It is no surprise, then, that divertor and exhaust physics is a major part of EUROfusion's reactor design work as part of their EU to the Realisation of Fusion Energy.

See the at the Culham Centre for Fusion Energy (CCFE) to find out more about the planned enhancements.

Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics have simulated a mysterious self-organized flow of the superhot plasma that fuels fusion reactions. The findings show that pumping more heat into the core of the plasma can drive instabilities that create plasma rotation inside the doughnut-shaped tokamak that houses the hot charged gas. This rotation may be used to improve the stability and performance of fusion devices.

The results, reported in January in the journal Physical Review Letters, use first principles-based plasma turbulence simulations of experiments performed on the DIII-D National Fusion Facility that General Atomics operates for the DOE in San Diego. The findings could lead to improved control of fusion reactions in ºÚÁÏÉçapp, the international experiment under construction in France to demonstrate the feasibility of fusion power.

In order to master what's commonly refered to as "the energy transition," a diversity of energy sources need to be matched up in the energy system of the future — decentralized and centralized, weather-dependent and continuously operable units.

The technological and economic interactions of all system components (generation, storage, load and transport facilities) and their intelligent networking are being tackled by the Energy System Integration project, which the Helmholtz Association is funding with five million euros in the next three years in the context of their Initiative and Networking Fund. The partners involved, including Max Planck Institute for Plasma Physics (IPP) at Garching und Greifswald, are making further contributions.

The aim of the research project is to model the architecture for an environmentally compatible, efficient and stable energy system of the future.

Expected as new primary energy source in the second half of the century are fusion power plants, environmentally and climatically friendly facilities supplying about one gigawatt of electric power. The contribution of IPP will therefore be to work out the physical and technical properties of these devices — of either the tokamak or stellarator type.
