The stellarator fusion device Wendelstein 7-X achieved record results during its three-month experimental campaign in 2018, reports the Max Planck Institute for Plasma Physics (IPP) in Greifswald, Germany.

In experiments run from July to October, operators were able to improve plasma temperatures and densities over the first campaign and achieve long discharge times of up to 100 seconds. A 30-second plasma at 6 MW was achieved with an input heating energy of 200 MJ, while at reduced power a 100-second plasma was achieved at 2 MW.

These results are "highly satisfying" and represent some of the best stellarator values to date, the press release reports. The team is now pursuing further engineering upgrades—notably the replacement of current plasma-facing components with actively water-cooled components—to enable even higher plasma energies and, ultimately, plasmas lasting 30 minutes.

You might wonder how many people are employed by the ITER Organization. Or how the staff pool breaks down in terms of hiring category, education level, gender or age. Or even something about family profile or Member representation.

With 35 countries participating, "diversity" is perhaps the word that best characterizes human resources at ITER. Find out more about hiring statistics, staff metrics, mobility, training, performance and more in the ITER Organizaton 2017 Social Report.

The fastest supercomputer in the world, Summit (launched earlier this year at the Oak Ridge National Laboratory in the US) will be instrumental in advancing fusion studies. Choong-Seock Chang, head of the Center for Edge Physics Simulation (EPSI) at the Princeton Plasma Physics Laboratory (US), studies the complex physics at the edge of fusion plasmas by running simulations on Summit. "It enables us to do physics which we have not been able to do before," he says.

According to Chang, scientists discovered that putting more heat into the edge of a plasma eliminated impurities and calmed the plasma. The supercomputer, featuring 2700 NVIDIA Volta GPUs, runs simulations to help get an understanding at the fundamental level of how these processes function. With the help of artificial intelligence, Summit will sift through the huge amount of simulation data and select the data with "the new physics."

The ultimate goal, says Chang, is to model the entire device and "build a virtual tokamak so that we can predict and design the next fusion reactor."

The Divertor Tokamak Test facility (DTT) is a new Italian fusion project that aims to address one of the major challenges identified in the European Fusion Roadmap: i.e., exhausting power from fusion reactors. The project is led by the Italian national Agency for New Technologies, Energy and Sustainable Development (ENEA) in collaboration with all the Italian fusion community and international institutions.

"DTT will mark a significant step forward for fusion development in Europe and worldwide," stresses DTT project leader Aldo Pizzuto, "and it will help to strengthen the industry involvement in fusion technology and engineering."

The DTT facility will be located in the ENEA premises in Frascati and the first industrial procurements for its components will be launched in early 2019. A DTT Industry Day will be held on 14 December 2018 in Frascati, which will be dedicated to the presentation of the procurement strategy and schedule. Business-to-business (B2B) meetings and bilateral thematic tables will also be organized.

Another Highly Exceptional Load (HEL) passes through the six-kilometre-long channel (the Canal de Caronte) that leads from the Mediterranean into the inland sea Étang de Berre through the town of Martigues.

The load consists of four transformers—one poloidal field coil rectifier procured by China and three central solenoid converters (89 tonnes each) procured by Korea. All four are "step down transformers" that lower the 66 kV tension to a few kilovolts before the AC current is transformed into DC to be fed to the magnets. The HEL convoy will begin its land journey on Wednesday and is expected at ITER in the wee hours of Friday. Three more poloidal field coil rectifiers, stored in DAHER facility in Berre, will hit the road on Wednesday 28 November to be delivered at ITER the following Friday.

The Chinese Academy of Sciences has reported that the Experimental Advanced Superconducting Tokamak (EAST) at the Institute of Plasma Physics in Hefei has achieved an electron temperature of over 100 million degrees in its core plasma during a four-month experiment carried out earlier this year in collaboration with domestic and international colleagues.

Power injection exceeded 10 MW, and plasma stored energy reached 300 kJ after scientists optimized the coupling of different heating techniques (lower hybrid wave heating, electron cyclotron wave heating, ion cyclotron resonance heating and neutral beam ion heating). The experiment utilized advanced plasma control and theory/simulation prediction.

Research at EAST on physics and technology issues under steady-state operational conditions is directly relevant to ITER. Recent experiments on plasma equilibrium and instability, confinement and transport, plasma-wall interaction, and energetic particle physics have demonstrated long-time scale, steady-state H-mode operation with good control of impurity, core/edge MHD stability, and heat exhaust using an ITER-like tungsten divertor.

The UK government has pledged to provide an additional £20m in 2019-20 to the UK Atomic Energy Agency (UKAEA), the public body responsible for research into nuclear fusion and the management of the country's largest fusion research laboratory, the Culham Centre for Fusion Energy (CCFE).

"We think fusion has a big role to play," said UKAEA CEO Professor Ian Chapman. "The fuels are abundant around the globe, it doesn't release greenhouse gases and it doesn't produce long-lived radioactive waste like the nuclear fission power we have today."

The 2018 Budget reaffirms the government's commitment to nuclear energy following an absence of new investments into the sector in the 2017 Budget.

According to the World Nuclear Association, nuclear power accounted for 21% of UK electricity in September this year, however "almost half" of the country's 15 reactors are expected to be decommissioned by 2025.

Thirty-seven seconds might seem like a very short duration—but not for a plasma, and even less for a plasma produced by a machine that is just commencing operations.

The 37-second plasma that WEST obtained on 31 October exceeds by 7 seconds the first of five milestones ("Key Project Indicators") that were assigned to the machine on its way to final commissioning.

The good news did not come alone—the final ITER-like, actively-cooled full tungsten divertor has just been ordered. It will replace the present non-actively cooled divertor made of tungsten-covered graphite blocks and only a few actively cooled test plasma-facing units.

When this new divertor is installed, WEST will be able to produce ITER-relevant plasmas of up to 1,000 seconds.

In the third week of November, the ITER Organization will be installing the first component of the machine in the basement of the Tokamak Building.

The 10-metre, 6-tonne metal component is one segment of the magnet feeder that will relay electrical power, cryogenic fluids and instrumentation cables from outside of the machine in to poloidal field coil #4. The specific section to be installed, called a "feedthrough," will cross through the bioshield and cryostat at the lowest (B2) level of the building.

Delivered by the Chinese Domestic Agency to ITER last year, the component has undergone testing at the MIFI workshop (Magnet Infrastructure Facilities for ITER), which is operated jointly by a team from ITER and the French Alternative Energies and Atomic Energy Commission (CEA).

Most recently, the lifting operation was tested at MIFI using a specially designed tool delivered by the Korean Domestic Agency (picture). Next week the component will be transferred by truck to a staging area, and then lifted up into the circular assembly area and lowered to the floor.

Stay tuned for a report in the 26 November issue of the ITER Newsline on the first act of the machine installation phase.

At the Troitsk Institute for Innovative and Fusion Research (Moscow region), specialists have established a unique remote control panel that enables participation on leading fusion devices around the world.

Based on the facility's lab complex for neutron and spectroscopy diagnostics, the panel will facilitate the creation and calibration of diagnostic systems for ITER under Russian procurement scope.

The first cooperation line has been established with Europe's JET tokamak, based in Culham, UK.  

Rich Hawryluk—who was Deputy Director-General for the Administration Department at the ITER Organization from 2011 to 2013—has been appointed interim deputy director for operations of the Princeton Plasma Physics Laboratory (PPPL) while an international search for a permanent operations director moves forward. 

Hawryluk will assume the position of Terry Brog, who is stepping down from his position. Brog will remain at the Laboratory for the next six months as the head of special assignments and will work on special projects for the Department of Energy and will help develop a technology transfer plan for the Laboratory. 

This is a familiar role for Hawryluk. He served as deputy director for 11 years from 1997 to 2008. Hawryluk came to PPPL in 1974 after receiving his Ph.D. in physics from MIT. During his 44-year career, he has worked on most of the major fusion experiments at PPPL. He was head of the Tokamak Fusion Test Reactor, then the largest magnetic confinement facility in the United States, from 1991 to 1997. After leaving his position as deputy director, he headed PPPL's ITER and Tokamaks Department from 2009 to 2011. From 2011 to 2013, he worked at ITER in France, serving as the deputy director-general for the Administration Department of ITER.  After returning to the Laboratory in 2013, Hawryluk headed the ITER and Tokamaks Department for three years. In 2016, he became head of the NSTX-U Recovery Project and headed that effort until becoming interim Laboratory director in September 2017.

Five years of construction work to upgrade the spherical tokamak MAST (UK) have been brought to a close and experiments are set to begin early next year.

MAST Upgrade will contribute to the knowledge base for ITER by helping to resolve key plasma physics issues. It will be the first tokamak to trial the Super-X divertor—a novel way to exhaust heat loads from large fusion reactors, which spreads the power loads in the divertor area of the machine. Other features of the upgrade include an increase in the pulse length by a factor approaching ten, additional heating power, and better control and pumping capabilities to contain the resulting higher temperature, longer-pulse plasmas.

A ceremony was held on 18 October at the UK's Culham Centre for Fusion Energy (CCFE). See the full report here.

Can ITER be the answer to the world's energy needs? A team from Al Jazeera Paris came on site in October to find out. After descending into the depths of the Tokamak Complex, interviewing the ITER Director-General and site specialists, and observing daily activities at ITER Headquarters over two days, team prepared a report that concludes with:

"Critics say there's a risk that ITER won't work or will never lead to fusion energy being commercially viable ... But if it does work it could help save the planet from climate change and prove the power of the human imagination. For those here, it's a gamble worth taking."

As part of an investment made last year by the UK Atomic Energy Authority (UKAEA) to launch a fusion technology platform at the Culham Centre for Fusion Energy (CCFE), the "Fusion Technology Facilities" (FTM) centre of excellence will house a suite of equipment designed to test fusion components under combined thermal, mechanical, hydraulic and magnetic loads representative of future fusion power stations.

In the build-up period, the team is establishing links to promote knowledge sharing and to support an ambitious industry-related research program. CCFE has just announced that a strong collaboration is planned between the Materials Technology Laboratory at FTM and the Department of Mechanical Engineering at the University of Bristol (UK). The establishment of complementary test equipment at Bristol and the funding of a joint post-doctoral research position are part of the agreement.
