OF INTEREST: ITER Day in Moscow: attracting the best minds

​On 21 May, directly after the regular class schedule, students, graduates and young scientists of the Moscow Institute of Physics and Technology had the chance to meet representatives of the Russian Domestic Agency. The exchange was organized as part of ITER Day to inform Russia’s future physicists about the international collaboration for fusion, progress in its implementation, and the ongoing activities in Russia carried out within its framework. The head of the Russian Domestic Agency, Anatoly Krasilnikov, stressed that attraction of young scientists for fusion is based not only on the potential of the ITER Project, but also the national development program for the construction of a domestic fusion facility. ‚This is the decades-long project and we need highly qualified personnel to work for it!’ ITER Russia is intensifying its activities to inform and attract the best minds. During ITER Day, students heard about development work on a number of diagnostic systems for ITER (reflectometry, neutron diagnostics, optical systems) underway in Russian institutes where, the speakers stressed, employments opportunities exist.

OF INTEREST: Pulsing power into the machine

​ITER’s Pulsed Power Electrical Network (PPEN) will supply alternating current (AC) power to the machine’s superconducting coils and heating and current drive systems. The Chinese Domestic Agency has full responsibility for the procurement of this powerful system; recently Manufacturing Readiness Reviews held at three industrial suppliers proved the high standards of design carried out so far and the readiness of the detailed work plans and execution processes. In the presence of a large number of Chinese experts as well as representatives from the ITER Organization, reviews were held on six system sub-packages in April. For the technical issues identified, a work schedule has been established. A major step forward toward manufacturing has been achieved for the PPEN, which will distribute up to 500 MW of continuous power during operational pulses. Czytaj dalej...

OF INTEREST: European labs to design the fast-ion diagnostic for ITER

​The European Domestic Agency for ITER, Fusion for Energy, has signed a four-year Framework Partnership Agreement with a consortium formed by European research centres—DTU Denmark and IST-IPFN Portugal—for the development and design of the Collective Thompson Scattering diagnostic for ITER. The primary objective of the Collective Thomson Scattering (CTS) diagnostic is to monitor fast ion behaviour across the plasma radius in seven locations. Fast ions are elusive particles that are a natural consequence of the fusion process and plasma heating techniques. Although they represent less than five percent of plasma density, fast ions carry up to one-third of the plasma’s kinetic energy. Optimizing their confinement within the plasma is important as they play a major part in sustaining the high plasma temperatures required for fusion by colliding with—and transferring their energy to—the ‚bulk’ particles in the plasma.   However, fast ions behave unpredictably; while some remain within the magnetic field, others escape the plasma and reduce confinement, or ’cause mischief’ by contributing their energy to and amplifying plasma disturbances.   The CTS diagnostic system will consist of mirrors and antennas integrated into one of the equatorial ports of the ITER machine. The upper antenna and mirrors will launch a powerful, single and high frequency microwave beam (1 MW at 60 GHz, equivalent to 1,000 microwave ovens at full power) into the plasma and record the scattered electromagnetic waves through the lower mirrors and receiver antennas. These measurements will allow scientists to establish the dynamics and distribution of the ions in the plasma—in particular the fast ions.   Read more on the Fusion for Energy and the DTU Denmark websites.

OF INTEREST: Superconductivity and magnetism in Turkey

​Every other year, Turkey organizes the International Conference on Superconductivity and Magnetism (ICSM). On 27 April-2 May, the fourth edition of the conference was held in Antalya, on the southwestern coast of the country, gathering more than 1,000 scientists from all over the world. At the special opening plenary session on 27 April, after a welcome speech by Annette Bussmann-Holder from the Max Planck Institute for Solid State, the next speaker gave a recollection of his long experience researching oxides—Alexander Müller, who earned the Nobel Prize in Physics in 1987 with Georg Bednorz, had just celebrated his 87th birthday and recalled having participated in the 1958 Geneva conference where the concept of tokamak was first discussed outside Russia. He is also the co-author of a patent on spherical plasma confinement.   Arnaud Devred, ITER Superconductor Section Leader, had the privilege of speaking just after Alexander Müller. His general presentation on the ITER Project focused on the magnet systems and detailed the present status of manufacturing. ‚I sensed a real interest in ITER,’ he says, ‚particularly from Prof. Ali Gencer, who chaired the conference and is a strong promoter of the project in government circles.’ Czytaj dalej...

NEWSLINE: ITER Robots: a laboratory for future engineers

Tusday 6 May was the final of the ITER Robots Contest, organized by Agence Iter France and the ITER Organization in collaboration with two French institutions—the Académie d’Aix-Marseille and the IRFM magnetic fusion research institute. For the second time running the city of Manosque was host to the competition, which has been run annually since 2012.   After nine months spent imagining, designing and programming their robots, ten teams—five from junior high school and five from high school—had the opportunity to put them to the test in front of a jury made up of professionals. ‚Getting involved in this contest is a glimpse into the life of a remote handling engineer,’ says engineer Jean-Pierre Friconneau, who works in remote handling at ITER. Alain Bécoulet, IRFM director, agrees: ‚The students tackled the kind of complex problem that we deal with every day of our professional lives in laboratory research.”   After a succession of time trials against the backdrop of cheers from some teams and sighs from others, students from the Gignac-la-Nerthe high school captured the victory with a robot called ‚ITERmine premier” (ITER the First). A question of luck? Or rather a result of the hundreds of hours the students in engineering science had spent to bring their idea to fruition …   The junior high students had a tougher time, with all teams facing last-minute problems and re-programming before the junior high school from the village of Pélissanne carried the contest. Once again, the competition reflected reality. ”A remote handling engineer faces this kind of problem on a regular basis. You have a design that might work in your laboratory, but that requires reprogramming when it’s in situation,” highlights Delphine Czytaj dalej...

OF INTEREST: Back to the future: are we about to crack energy fusion?

Can we harness the energy of an earth-bound sun? It’s a question that has obsessed and perplexed scientists for more than half a century. According to Professor Steve Cowley, director of the Culham Centre for Fusion Energy (CCFE) and chief executive of the United Kingdom Atomic Energy Authority, it remains one of the "great quests" in science. For the uninitiated, it’s the kind of big idea that makes your head spin: we’re talking about mimicking the process that powers the stars, heating hydrogen atoms to temperatures in excess of 100 million degrees celsius — the point at which they fuse into heavier helium atoms — and releasing energy in the process.   The creation of a self-sustaining reaction here on earth would be a revolutionary moment for humanity. It would mean we’d have a near-limitless source of energy that is clean, safe and cheap. The fuel used for fusion (two isotopes of hydrogen, deuterium and tritium) is so abundant it will effectively never run out; one kilogram of it provides the same amount of energy as 10 million kilograms of fossil fuel. And while some fusion reactor components would become mildly radioactive over time, they should be safe to recycle or dispose of conventionally within 100 years, according to fusion experts.   Read the whole article on The Guardian website.
