ºÚÁÏÉçapp

The ºÚÁÏÉçapp neutral beam injectors will be first of a kind, operating at 1MV with negative ion beams up to 40A. As part of a risk mitigation strategy, the ºÚÁÏÉçapp is testing key system components in advance of operation at the ºÚÁÏÉçapp Neutral Beam Test Facility in Padua, Italy. This facility, housed at the Consorzio RFX laboratory, is the only one in the world capable of demonstrating ºÚÁÏÉçapp heating neutral beam requirements simultaneously.

Experiments began last year on SPIDER, a full-scale negative ion source. A second testbed will come on line in 2022: MITICA, a full-scale prototype 1 MV injector that will allow scientists to test and optimize the beam source, accelerator, and beamline components.

Work is progressing on the assembly of the MITICA test bed now. Acceptance tests have been run on the high voltage power sources supplied by Europe and Japan (see this page for photos) and, recently, Europe delivered the vacuum chamber that will house the MITICA beam source (photo).

The 5-metre-tall, 67-tonne chamber was manufactured by De Pretto Industrie (Italy) under a contract signed with the European Domestic Agency Fusion for Energy.

Funding has been secured for the Joint European Tokamak (JET) through the end of 2020, providing welcome visibility to the world's largest operating fusion research facility in the context of uncertainty surrounding Brexit.

The future of JET has been under discussion since 2017 as its work is covered by the Euratom Treaty, which the UK Government intends to leave as part of the process of leaving the European Union.

The new contract signed last week between the UK and the European Commission provides reassurance for over 500 staff at JET, including many from outside the UK. It also means JET can conduct a series of vital fusion tests planned for 2020 that will serve as a "dress rehearsal" for ºÚÁÏÉçapp.

JET is operated by the UK Atomic Energy Authority at the Culham Centre for Fusion Energy (CCFE). Scientists from 28 European countries use it to conduct research into fusion energy through work coordinated by the , which manages and funds European fusion research activities on behalf of Euratom.

Ian Chapman, CEO of the UK Atomic Energy Authority, said: "The extension to the contract is excellent news for both European Union and UK science. JET has been a shining example of scientific cooperation between European Union members, and this news means that these mutually beneficial collaborations will continue, allowing us to do essential experiments on the path to delivering fusion power."

Tony Donné, Programme Manager of EUROfusion, added: "A heavy weight has been lifted off our shoulders. This is extraordinarily good news for EUROfusion and the European fusion community as a whole. We can now continue to work on the realization of fusion energy together with the indispensable experience of our British partner."

Fusion scientists keep looking for ways to address the challenge of plasma disruptions, which can halt fusion reactions and potentially damage the plasma-facing components of a fusion device.

Researchers at the Princeton Plasma Physics Laboratory (PPPL) and the University of Washington have developed a prototype device to control plasma disruptions. The electromagnetic particle injector, EPI, is a type of railgun that fires a high-velocity projectile, a sabot, from a pair of electrified rails into a plasma that is on the verge of disruption. The sabot releases light-metal pellets into the centre of the plasma that would spread out the energy of the disruption from the centre of the plasma to the edge, thus weakening its impact on the vessel walls.

The EPI can deliver the pellets more deeply into the plasma than other techniques. For physicist Roger Raman of the University of Washington, the primary advantage of the new device is "its potential to meet short-warning time scales." Pellets should be delivered in less than 20 milliseconds from the warning of a disruption, with 10 milliseconds as ideal. During tests, the EPI delivered pellets in less than 10 milliseconds. In comparison, the gas-propelled system needs 30 milliseconds.

Researchers at the Los Alamos National Laboratory in the United States have developed thin films made of a tungsten alloy that could be used inside fusion reactors. The material, a nanocrystalline tungsten-tantalum-vanadium-chromium alloy, showed "outstanding radiation resistance when compared to pure nanocrystalline tungsten materials," said researcher Osman El Atawi in an article published in .

The inside of a fusion reactor vessel faces the hot plasma and must withstand extremely high temperatures as well as bombardment by charged and neutral particles. Tungsten, which is currently considered the most suitable material to protect the inside of a vacuum vessel, tends to fracture after radiation, while the newly developed alloy material retains its mechanical properties.

Osman El Atawi (left) and Enrique Martinez collaborated with researchers from several scientific institutes in the United States, Poland and the United Kingdom. Their joint paper is published in .

What do you get when you mix three parts fusion doctoral training, two measures of outreach, many parts of information, and a final jigger of fun?

A Glass of Seawater!—a self-described "light, informative, and inspiring podcast all about the field of fusion energy research as seen through the eyes of PhD students from FUSION CDT*."

Now in its third season, the podcast takes on all kinds of nuclear fusion/plasma physics topics from, as the organizers are happy to admit, a "glass half full" perspective. What is incredibly hard—but also exciting—about research in fusion today? Which challenges have been overcome and which remain? What are the latest developments from the world of materials science? And—last but not least—how much fuel for the fusion reaction can be taken from a glass of seawater?

Tune in to Andrew, Bhavin, William and their many guests , or look up A Glass of Seawater! on Facebook and Twitter.

Established in December 1893, the monthly L'Usine nouvelle ("The New Factory") is one of the oldest French trade magazines. To celebrate its 125th anniversary, the magazine organized a major travelling photography exhibit that will be presented at several engineering schools in France and eventually, in 2020, at the Palais du Luxembourg—home of the French Senate in Paris.

"" brings together spectacular aerial photographs of industrial installations and infrastructure in France and abroad. And ºÚÁÏÉçapp is one of them.

The organizers chose a composite photo created by ºÚÁÏÉçapp contractor Emmanuel Riche from several drone views of the ºÚÁÏÉçapp site taken at dusk in December 2017. The resulting "planet"—centred on the Tokamak Building and its circular bioshield, with cranes jutting out at the "equator"—is one of the most spectacular renditions of the ºÚÁÏÉçapp site, in both its artistic and its documentary approach.

A photo of a specimen of tungsten-fibre-reinforced tungsten after a stress test won the first prize in science publisher Elsevier's "NuMart Image Competition". Johann Riesch and colleagues at the Max Planck Institute for Plasma Physics (IPP) developed the composite material as part of the search for materials that could be used at high-stress locations in fusion plasma vessels.

Although tungsten is the metal with the highest melting point, it is highly brittle and develops cracks under punctual stresses. Taking their cue from fibre-reinforced ceramics, Riesch and his team developed tungsten-fibre-reinforced tungsten where tungsten fibres with a diameter of 150 micrometres bridge the cracks in the tungsten matrix.

The photo taken by Martin Balden shows the new material after a breaking test as seen by an electron-microscope, demonstrating how the fibres enhance the fracture toughness of the tungsten material. The image will feature on the cover of the jubilee issue of Elsevier's Journal of Nuclear Materials, which will be published in April 2019, marking its 60th anniversary.

Thousands of live webcams throughout the world provide viewers with spectacular natural vistas, cityscapes and beaches, trendy bars and colourful markets in real time. Every year the network, a website that collects webcams from thousands of sites across the globe, selects 25 of the most interesting views offered to the public.

As expected, webcam #1 in 2018 was pointed at a beautiful natural scene—the Arenal volcano in Costa Rica which, until a few years ago, was one of the most active in the world. There were also cats among the first tier of the awardees.

The surprise however came with webcam #18, the Remote Glow Discharge Experiment (RGDX) at the Princeton Plasma Physics Laboratory (PPPL), over which the EarthCam editors confessed they were "geeking out."

The RDGX allows viewers to turn on a plasma and change the gas pressure, the voltage, and the strength of the electromagnets from any place in the world.

Along with a webcam focused on a light bulb that has been shining at the Livermore, California, Fire Department for... 117 years ... and an interactive robot-controlling cam in Oakland, also in California, Princeton's RDGX is the only science- and technology-oriented webcam to make the first "25 most interesting webcams" in the world.

At the Culham Centre for Fusion Energy (CCFE), researcher Fulvio Militello is working on a statistical model that compares the seemingly random movement of filaments (structures that emerge at the edges of the hot plasma) to the behaviour of raindrops. In the same way that each unique raindrop follows the same laws of physics (they hit the pavement), filaments that differ in strength, speed, size, amplitude or position follow certain rules as they move. Militello's model estimates collective behaviour in order to give scientists a tool to predict and control them. Read more about his theory on the .

In working with data from the DIII-D tokamak, physicists Ahmed Diallo and Julien Dominski from the Princeton Plasma Physics Laboratory (PPPL) have uncovered a trigger for a particular type of ELM—fiery bursts of plasma called Edge Localized Modes—that does not fit into present models. Their findings could shed light on the variety of mechanisms leading to the onset of ELMs and could broaden the portfolio of ELM suppression tools. Read the full report on the .

On October 9 2014, fusion research bodies from European Union member states and Switzerland signed an agreement to cement European collaboration on fusion research and EUROfusion—the European Consortium for Development of Fusion Energy—was born.

Researchers at the Princeton Plasma Physics Laboratory in the US are reporting findings that can be beneficial to ºÚÁÏÉçapp, says John Greenwald on the laboratory's website.

Results published by theoretical physicist Allan Reiman and his colleague Professor Nat Fisch in focus on so-called tearing modes—instabilities in the plasma that create magnetic islands, which are a key source of plasma disruptions.

Currents driven by radio frequency waves in the interior of these magnetic islands can stabilize deleterious tearing modes, an effect that is augmented by small perturbations in the plasma's temperature.

"When the power deposition in the island exceeds a threshold level, there is a jump in the temperature that greatly strengthens the stabilizing effect," says Reiman. "This allows the stabilization of larger islands than previously thought possible."

Like mountaineers at the foot of Mount Everest, spacefaring nations have aimed for the Moon "because it's there." Now, close to 60 years after the first object from Earth landed (or more accurately "") on the surface of our satellite and half a century after Apollo 11 gently deposited two men on the Sea of Tranquility, there are very concrete incentives to 21st century lunar exploration.

And one of these incentives has to do with the future of fusion.

Research today is essentially focused on the fusion of hydrogen isotopes deuterium and tritium, which is the "easiest" to achieve with our present technological capabilities. However, other energy-producing combinations of light nuclei are theoretically possible, a few of which involve the helium isotope 3 (3He). Fusing 3He with itself or with deuterium offers the immense advantage of not producing neutrons and hence avoids activating materials in the fusion chamber.

Carried by solar wind, 3He is prevented from reaching the surface of our planet because of the magnetic field that protects it. On the Moon however, where the magnetic field is considerably weaker, large quantities of 3He have accumulated close to the surface. For many years, some scientists, politicians, and private companies (and even a former Apollo astronaut) have made the argument for "mining the Moon" for 3He. Other scientists argue that mining the Moon for 3He is pure ... .

Despite the controversy, 3He recently made headlines in relation with the recent landing of the Chinese rover Chang'e 4 on the dark side of the Moon. Professor Ouyang Ziyuan, the Chief Scientist of the Chinese Lunar Exploration Program, was widely saying that a long-term industrial program to mine the Moon for 3He was economically justified.  "The moon is 'so rich' in helium 3," he said, "that it could solve humanity's energy demand for around 10,000 years at least."
