Four turbines produced for ºÚÁÏÉçapp's liquid nitrogen (LN2) cryogenic plant have successfully passed factory acceptance testing and will be delivered to ºÚÁÏÉçapp this autumn.

One oil brake turbine and one turbine booster will be installed in each of the cold boxes of the LN2 plant, which is under European procurement.

The liquid nitrogen plant and auxiliary systems will cool down, process, store, transfer and recover the cryogenic fluids of the machine. Two nitrogen refrigerators will be delivered along with two 80 K helium loop boxes, warm and cold helium storage tanks, dryers, heaters and the helium purification system.

In spite of the small diameter of the turbines—not exceeding 15 cm—these tiny pieces of equipment will generate enough cooling power to keep the ºÚÁÏÉçapp thermal shields extremely cold. It took Air Liquide contractor Cryostar (France) eight months to complete fabrication.

Latin America's first stellarator was officially inaugurated on 29 June 2016.

The small SRC-1 stellarator device was planned and built by the Plasma Laboratory for Fusion Energy and Applications, which belongs to the Costa Rica Institute of Technology () in Cartago.

The countdown for producing the first plasma was started by a high-ranking government representative from Costa Rica and the TEC President and was witnessed by guests from science and politics. Electronic congratulations had been sent by representatives of international stellarator research from Princeton (US) and IPP at Greifswald (Germany) to mark the advent of the new device.

"Our work is to serve future generations," stated Institute Director Iván Vargas. "If research like this continues to evolve, in the future this technology could be used at a power plant that would take alternative energy to our communities."

The Plasma Laboratory for Fusion Energy and Applications was founded six years ago. It covers the fields of plasma medicine, industrial plasma technology and fusion research. Work hitherto had been concentrated on the small MEDUSA-CR device (Madison Education Small Aspect ratio tokamak), which was taken over from the University of Wisconsin-Madison, and on the preparation of the SCR-1 stellarator.

The investment costs for SCR-1 came to USD 500,000. The plasma vessel and modular coils were made in Costa Rica. The small device aims to attain plasma temperatures of 300,000 degrees Celsius. Latin America's first stellarator now joins the ranks of the stellarators in Australia, Germany, Japan, Spain and the USA.

In June, the Budker Institute in Russia was host to two meetings on ºÚÁÏÉçapp diagnostics, with at least 70 international specialists attending.

The members of the Diagnostics Topical Group, ITPA (International Tokamak Physics Activity) met for the 30th time to discuss a range of internationally coordinated research areas that are important to the development of ºÚÁÏÉçapp and fusion diagnostic systems. Topics included progress on diagnostic mirrors, which must withstand conditions close to the high-temperature plasma; diagnostics for alpha particles; plasma wall reflections; and plasma control. In parallel, a meeting on port integration reunited several Russian organizations that are—like the Budker Institute—involved in the engineering integration of diagnostics into the ºÚÁÏÉçapp port plugs.

In addition to diagnostic engineering, the Budker Institute plays a key part in the development of high-tech electron equipment, research into the investigation of high-temperature plasma on first-wall materials, and the development, manufacturing, and testing of equipment for the ºÚÁÏÉçapp machine.

Michal Walsh, head of the Port Plugs & Diagnostics Integration Division at ºÚÁÏÉçapp, toured the host facilities in the company of the ITPA members. "Given the technical potential of this research centre and our successful cooperation to date, I look forward to continued cooperation in the future."

"The proponents of fusion power have for years been promising us a plentiful and relatively safe form of new energy. Well here, at ºÚÁÏÉçapp in France, they are starting to make good on that promise."

So begins the 30-minute documentary film on ºÚÁÏÉçapp and fusion that aired this past weekend on BBC Horizons.

Presenter Adam Shaw visits ºÚÁÏÉçapp in the south of France as well as labs around the world (Germany, US and Canada) to learn more about the "tantalizing possibility" of fusion and its chance at transforming the world's relationship with energy.

Three additional ºÚÁÏÉçapp cryostat segments have arrived in the port of Fos-sur-Mer after a one-month voyage from India.

The 60° segments make up half of Tier 2 of the cryostat base (three other Tier 2 segments are due at a later date). The 120-tonne components have been unloaded in Fos in preparation for their delivery to the ºÚÁÏÉçapp site this week (weather permitting) along the ºÚÁÏÉçapp Itinerary.

Each 96-wheel transport trailer will carry a protected load that is just over 14 metres long and six metres wide.

In a tokamak fusion reactor, the plasma causes intense heating of the divertor, similar to that encountered by a space shuttle when it re-enters the Earth's atmosphere. The belly of the shuttle must be protected by special heat tiles. In the same way, the divertor surface is made of small tungsten tiles that are tilted at a grazing angle with respect to the plasma stream. The edges of the tiles, like the nose and wings of the shuttle, are subject to very intense heat flux...

At Cadarache (south of France), the Institute for Magnetic Fusion Research (CEA/DSM/IRFM) is modifying the Tore Supra plasma facility to become a test platform open to all ºÚÁÏÉçapp partners. WEST stands for W (tungsten) Environment in Steady-state Tokamak. 

With transparent skies and 300 days of sunshine a year, the tiny Alpine village of Saint-Véran (alt: 2,042 metres) offers a unique viewpoint on our own familiar fusion furnace. In the 1970s professional astronomers from the Observatoire de Paris used it to observe the Sun's corona with instruments they eventually donated to the village.

Walking in the scientists' footsteps, the local population soon developed a passion for solar astronomy—an amateur club was created, more instruments were acquired through donations and the municipality soon decided to capitalize on its privileged relationship with the Sun.

La Maison du Soleil was inaugurated on Thursday 9 June in the presence of French Vice-Minister for Higher Education and Research, Thierry Mandon, and of ºÚÁÏÉçapp Director-General Bernard Bigot.

Designed for the general public, La Maison du Soleil will organize exhibits, conferences and solar observations. Nuclear fusion and ºÚÁÏÉçapp are of course part of the permanent exhibit, with posters, panels ... and even a conductor sample provided by the ºÚÁÏÉçapp Magnets Division.

Saint-Véran is located in the heart of the Queyras Regional Park, two-and-a-half hours north of ºÚÁÏÉçapp.

The third edition of Introduction to Plasma Physics and Controlled Fusion by author Francis F. Chen is now available from Springer (follow this ). In addition to updates in all chapters, the 2016 release includes new chapters on special plasmas and plasma applications.

While the fusion community continues its quest to harness fusion for energy needs, numerous spin-off benefits are resulting from the research carried out all over the world.

Given its complex, multidisciplinary nature, it should be no surprise that fusion research has driven advances in disciplines ranging from medical technology and environment to astrophysics and material sciences. , the European Consortium for the Development of Fusion Energy, has identified some of these spin-offs and put together a non-exhaustive list that demonstrates the short-term benefits of fusion research on the way to fusion electricity.

Two types of cameras will be needed inside of the ºÚÁÏÉçapp vacuum vessel to support inspection and maintenance operations—oversight cameras that give engineers a broad view inside the vacuum vessel, and cameras embedded on tooling or robotics for a view inside tightly confined spaces.

The European Domestic Agency for ºÚÁÏÉçapp is working with industry to develop purpose-built equipment small enough to fit into tight space constraints and capable of withstanding the harsh conditions close to the plasma.

In a project called FURHIS (for FUsion for Energy Radiation Hard Imaging System), Europe is collaborating with Oxford Technologies (UK) to produce mockups of sub-systems that will soon be tested in a radiation environment. Working with French laboratories ISAE (image sensors), CEA (LED illumination system), and Université Jean Monnet (optic system), a 15 mm mockup—small enough to fit inside a one euro coin—has been developed.

The FURHIS sub-systems will now be tested at the Belgian Nuclear Research Centre SCK•CEN.

Ronald C. Davidson, a pioneering plasma physicist for 50 years who directed the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) during a crucial period of its history and was a founding director of the Plasma Fusion Center at the Massachusetts Institute of Technology (MIT), passed away on 19 May at his home in Cranbury, New Jersey. He was 74.

"Ron was an anchor for the Laboratory both through his science and through his wisdom," said Stewart Prager, director of PPPL. "His prodigious contributions not just to PPPL's science but also to plasma physics writ large are clear and widely known. Within the Laboratory, he was a mentor and a guide to people young and old. His impact within the Laboratory was enormous."

The physicist won numerous honours in his lifetime, including the prestigious James Clerk Maxwell Prize in Plasma Physics in 2008, the highest national honour in plasma physics. He was a fellow of both the American Physical Society and the American Association for the Advancement of Science. Davidson was known as a prolific researcher, writer and academic.

On the last day of her state visit to France, South Korea's President Park Geun-hye stopped in Grenoble, a city in the French Alps where she studied in the mid-1970s after graduating from South Korea's Sogang University.

Nostalgia wasn't the only reason for this last stop, however. The South Korean President wished to visit the Air Liquide plant in Sassenage, where hydrogen fuel cell vehicles are being developed in cooperation with the Korean automaker Hyundai Motor Co.

Also of interest to President Park were the ºÚÁÏÉçapp cold boxes that are currently being equipped with internal components before integration into the ºÚÁÏÉçapp cryoplant.

One of the three ºÚÁÏÉçapp cold boxes (21 metres long, 4.2 metres in diameter) provided a spectacular background to the presentation of the company's activities by Xavier Vigor, Air Liquide advanced Technologies CEO. Also present were Benoît Potier, Air Liquide Chairman and Chief Executive Officer, and Pierre-Etienne Franc, Vice President of Advanced Business & Technologies.

It was the second time the ºÚÁÏÉçapp cold boxes were in presidential company: in August 2015 French President Hollande also made a stop at the Air Liquide plant and even signed cryoplant cold box number two ...

New computer simulations at the Princeton Plasma Physics Laboratory (PPPL) indicate that an innovate start-up technique for tokamaks, called coaxial helicity injection (), may support a strong electric current without a traditional solenoid magnet.

In tokamaks, a complex web of magnetic fields control the superhot plasma. In addition to large D-shaped magnets surrounding the vacuum vessel, a central electromagnet known as a solenoid participates in creating the twisting vortex that prevents the plasma from touching the tokamak's walls.

Compact spherical tokamaks, like the NSTX-U recently at PPPL, as well as future tokamaks may not have room for solenoids. During CHI, magnetic field lines, or loops, are inserted into the tokamak's vessel through openings in the vessel floor. The field lines then expand to fill the vessel space, like a balloon inflating with air, until the loops undergo a process known as magnetic reconnection and snap closed. The newly formed closed field lines then induce current in the plasma.

"Can we create and sustain a big enough magnetic bubble in a tokamak to support a strong electric current without a solenoid?" asks Physicist Fatima Ebrahimi, who performed the computer simulations. "The findings indicate that 'yes, we can do it.'"

In a report to the US Congress released on 26 May, the Department of Energy (DOE) recommends "that the US remain a partner in the ºÚÁÏÉçapp project through Fiscal Year 2018," at which time the country's participation in the project will need to be reassessed.

"At this time, our continued participation [...] is in the best interest of the nation," writes Energy Secretary Ernest Moniz in the introductory message to the report.

The 17-page report notes that "the management of the ºÚÁÏÉçapp and the performance of the project have improved substantially" under Bernard Bigot's leadership. "The project is now being well-run."

However, "the improvements and performance, while promising, still require additional time to determine if they will be sustained and lead to the long-term success of the project."

Despite the accumulated delays "ºÚÁÏÉçapp remains the fastest path for the study of burning plasma," concludes the report.

The ºÚÁÏÉçapp will participate in this year's international symposium Atoms for the Future—the annual meeting of students and young professionals from the nuclear field (more information ). ºÚÁÏÉçapp Director-General Bernard Bigot will be among the speakers on 27 June 2016, and two days later students will have the possibility to visit the ºÚÁÏÉçapp site in southern France.

Registration for Atoms for the Future also gives you access to the (28-30 June 2016) where the ºÚÁÏÉçapp will be also be present.

US Department of Energy (DOE) Secretary Ernest Moniz dedicated the most powerful spherical torus fusion facility in the world on 20 May 2016. The $94-million upgrade to the National Spherical Torus Experiment (NSTX-U), funded by the DOE Office of Science, is a spherical tokamak fusion device that explores the creation of high-performance plasmas at 100-million degree temperatures.

NSTX-U at the Princeton Plasma Physics Laboratory (PPPL) will allow researchers around the world to explore fusion reactions [...] "The vastly expanded capabilities of this spherical tokamak will enable us to explore new physics regimes and tackle the major engineering problems for fusion energy," Moniz said.

NSTX-U draws on a 65-year-old legacy of fusion energy research at Princeton University's Plasma Physics Laboratory where, in the 1950s, physicist Lyman Spitzer created a machine he called a stellarator to produce energy the same way as the Sun. Experimental stellarators and tokamaks, the two most prominent fusion reactor designs, now dot the globe.

"This is exciting new territory, and we're thrilled to embark on the next frontier of fusion research. This device could transform the world by showing us the way to a pilot plant design for the generation of power from fusion energy for use by all," said Stewart Prager, director, Princeton Plasma Physics Laboratory.
