ºÚÁÏÉçapp

On 8-9 September the final acceptance meeting was held for the Cryostat Workshop. This 5,500-square-metre building will be the theatre for the assembly of the four main cryostat sections from 54 smaller segments manufactured in India.   As the contractor chosen by the Indian Domestic Agency for the construction and assembly of the ºÚÁÏÉçapp cryostat, Larsen & Toubro Limited is also in charge of the on-site cryostat worksite. The company awarded the construction contract to the French company SPIE Batignolles TPCI, who began work just over a year ago, in June 2013.   "Larsen & Toubro (L&T) takes pride in having completed the temporary workshop before the contractual delivery date," a company statement read. "This was possible due to the positive and collaborative efforts by all of the teams involved: SPIE Batignolles TPCI, Danieli (crane contractor), Currie & Brown (engineering), Apave (health and safety protection), ºÚÁÏÉçapp India and the ºÚÁÏÉçapp. Larsen & Toubro is thankful to all of these teams for their role in achieving this feat."

​The process of magnetic field line reconnection, in which the magnetic field lines in a plasma snap apart and violently reconnect, transforms magnetic field energy into particle energy. Little was known about this phenomenon that is known most prominently in the form of solar flares on the surface of the sun. The subsequent geomagnetic storms on earth have demonstrated how much energy can be released by magnetic reconnection.

In the research conducted on the Magnetic Reconnection Experiment (MRX) at PPPL, scientists measured experimentally the amount of magnetic energy that turns into particle energy. They showed that reconnection converts about 50 percent of the magnetic energy in the plasma, with one-third of the conversion heating the electrons and two-thirds accelerating the ions.

The findings also suggested the process by which the energy conversion occurs. According to the researchers, reconnection first propels and energizes the electrons, which creates an electrically charged field that becomes the primary energy source for the ions.

​A weird type of 'hybrid' star has been discovered nearly 40 years since it was first theorized — but until now has been curiously difficult to find.

In 1975, renowned astrophysicists Kip Thorne, of the California Institute of Technology (Caltech) in Pasadena, Calif., and Anna Żytkow, of the University of Cambridge, UK, assembled a theory on how a large dying star could swallow its neutron star binary partner, thus becoming a very rare type of stellar hybrid, nicknamed a Thorne-Żytkow object (or TŻO). The neutron star — a dense husk of degenerate matter that was once a massive star long since gone supernova — would spiral into the red supergiant's core, interrupting normal fusion processes.

On 11 August, during the opening session of this year's Applied Superconductivity Conference in Charlotte, North Carolina (US), ºÚÁÏÉçapp's Arnaud Devred received the IEEE award "for continuing and significant contributions in the field of applied superconductivity."

The prestigious prize delivered by the was awarded for his "many and significant contributions to the field of large scale applications." 

 "I am indebted to many people, who have inspired me and made me the person I am today," said the head of the ºÚÁÏÉçapp Superconductor Systems & Auxiliaries Section in his acceptance speech. "One of my greatest privileges—and rewards—is that throughout my carrier I have been able to meet and work with great people. First in Europe, then in the US and Japan, and now from all around the world. Therefore, I would like to share this award with my numerous collaborators in China, Europe, Japan, Korea, Russia and the United States, and, in these times of heightened political tensions, it is my wish that we can keep working together in the same open and peaceful manner—our little contribution to making the world a better place to be."

Last Saturday 13 September, the fourth edition of the ºÚÁÏÉçapp Games attracted a crowd of close to 250 competitors and their supporters for an all-day sports event including football and tennis competitions, a cross-country run, a kayak race and a petanque tournament. For the participants—people working for the ºÚÁÏÉçapp Project, club members from the local sports associations, and their families—this was another opportunity to meet, compete and share ... all ways to strengthen ties between ºÚÁÏÉçapp and its environment. (Photo AIF-AP)

​Hutch Neilson, Princeton Plasma Physics Laboratory's (PPPL's) head of Advanced Projects, is saying "auf wiedersehen" to the lab for the next nine months as he travels to Greifswald, Germany, where he will be paving the way for future US researchers to participate on the Wendelstein 7-X (W7-X) program as the experiment begins preparing for operations next year.

David Gates, a principal research physicist and the stellarator physics leader at PPPL, will be serving as Interim Head of Advanced Projects in Neilson's absence.

Neilson's new position comes after the US Department of Energy and the European Atomic Energy Commission signed an agreement in June establishing a long-term partnership with the Max Planck Institute for Plasma Physics (IPP) and PPPL, Oak Ridge National Laboratory and Los Alamos National Laboratory. The agreement names PPPL as the lead institute for the US collaboration on the W7-X.

​At the onset of the atomic age, governments on both sides of the iron curtain sought to harness the power of nuclear fusion. Researchers at the Princeton Plasma Physics Laboratory in New Jersey stood at the forefront of the American effort when, in 1953, they began using Stellarators — one of the earliest controlled fusion systems.

Early fusion research in the western world nearly immediately split into two halves after the end of WWII, with one subset of researchers observing super-compressed fusion materials at very short timescales, the others — including Dr. Lyman Spitzer, chair of the Department of Astronomy at Princeton University — observing these materials at a lower compression for longer times. Spitzer's invention served this purpose wonderfully. The Stellarator that Spitzer invented in 1950 is designed to hold superheated, electrically-charged plasma — a most vital and basic component of nuclear fusion research — within a designated field using electromagnetic currents.

​Scientists have long believed that the power of the sun comes largely from the fusion of protons into helium, but now they can finally prove it. An international team of researchers using a detector buried deep below the mountains of central Italy has detected neutrinos—ghostly particles that interact only very reluctantly with matter—streaming from the heart of the sun. Other solar neutrinos have been detected before, but these particular ones come from the key proton-proton fusion reaction that is the first part of a chain of reactions that provides 99% of the sun's power.

The results also show that the sun is a remarkably steady power source. Neutrinos take only 8 minutes to get from the sun's core to Earth, so the rate of neutrino production that the team detected reflects the amount of heat the sun is producing today. It just so happens that this is the same as the amount of energy now being radiated from the sun's surface, even though those photons have taken 100,000 years to work their way from the core to the surface. Hence, the sun's energy production hasn't changed in 100 millennia. "This is direct proof of the stability of the sun over the past 100,000 years or so," says team member Andrea Pocar of the University of Massachusetts, Amherst.   Read more on website

​Tucked away from major roadways and nestled amid more than 80 acres of forest sits a massive warehouse-like building where inside, a device that can produce temperatures hotter than the sun has sat cold and quiet for more than two years.

But the wait is almost over for the nuclear fusion reactor to get back up and running at the Princeton Plasma Physics Laboratory.

"We're very excited and we're all anxious to turn that machine back on," said Adam Cohen, deputy director for operations at PPPL.

The National Spherical Torus Experiment (NSTX) has been shut down since 2012 as it underwent a $94 million upgrade that will make it what officials say will be the most powerful fusion facility of its kind in the world. It is expected to be ready for operations in late winter or early spring, Cohen said.

[...]

The upgrade (NSTX-U) will essentially double the power of the reactor by increasing the heat, electrical current and magnetic field. A second [device] that helps heat the plasma was added, and the center magnet, which resembles the core of an apple, was rebuilt to create a stronger magnetic field.   "We may reach several hundred million degrees Celsius in the new machine," said Masa Ono, a research physicist and head of the NSTX department.   Access the full story, image gallery and video interview at .

​In Rokkasho, on the eastern coastline of Japan, Europe and Japan are jointly carrying out advanced R&D activities in support of ºÚÁÏÉçapp and for successful development of the phases after ºÚÁÏÉçapp. Termed the "Broader Approach," these efforts have been underway since 2007.

In early August, the Director-General of the ºÚÁÏÉçapp, Osamu Motojima, and ºÚÁÏÉçapp Council Secretary, Sachiko Ishizaka, visited Rokkasho for an update on Broader Approach activities and to share information about progress at ºÚÁÏÉçapp.

 The activities of the Broader Approach are essential for the phases after ºÚÁÏÉçapp in the world fusion program. One project, , is validating the concept for a fusion-relevant neutron source based on Li(d,xn) reactions and will permit the rapid construction of such a facility within cost and schedule less than a decade from the time that a decision is taken. Another—IFERC—not only holds a supercomputer that dedicated to plasma simulations for the world fusion community (), but is also implementing research efforts towards a (post-ºÚÁÏÉçapp) DEMO reactor.

 After visiting the facilities—including the injector of LIPAc, the Linear IFMIF Prototype Accelerator (LIPAc) that is presently under installation and commissioning—the visitors from ºÚÁÏÉçapp were able to appreciate the sound advancements and robust health of the Broader Approach projects.

Four crates containing parts of an ºÚÁÏÉçapp electrical transformer (high voltage surge arresters) left the port of New York on 5 August; delivery to the ºÚÁÏÉçapp site in France is expected late September. The components were manufactured by ABB in Mount Pleasant, Pennsylvania.

​FOR years, scientists just down the road from Oxford have been quietly working at the forefront of a project that could change the world.

But fusion power is the best invention you have probably never heard of. That may sound like a bold claim, but Prof Steve Cowley, chief executive officer of the Culham Centre for Fusion Energy, is convinced that it is the only solution to a fast-approacing world energy crisis. He has been working at the science centre since 2008, but the project — the Joint European Torus (JET) — has been under way since 1982. Its aim: to create the conditions of a star on the Earth, producing clean, cheap energy for us to power our televisions, kettles and lightbulbs. Read more on the Oxford Mail .

​Culham Center for Fusion Energy, in a consortium with UK universities and Rutherford Appleton Laboratory, is developing a concept for a large neutron source to test materials for future fusion power plants including the proposed prototype, DEMO, that will follow the ºÚÁÏÉçapp project.

If approved, the FAFNIR project would give the designers of DEMO crucial data on materials with which to build the machine. It would also serve as a bridge to the planned , which is expected to play a similar role for the first generation of commercial fusion reactors. Fusion scientists and engineers are increasingly focusing on materials research as attention turns to designs for reactors that will put power on the electricity grid. The extremely fast neutrons produced by fusion reactions in tokamaks carry an energy of 14 million electron volts (MeV) — about 70 times more than photons in hospital x-ray equipment — and pose a threat to the tokamak's structures. The neutrons cause damage within the structure of the material which leads to swelling through the creation of voids. Effects such as embrittlement and hardening of the metal caused by accumulation of helium and hydrogen gases produced by transmutation (transformation of one element into another) mean that special materials must be developed that can stay the course throughout the reactor's lifespan. As a result of transmutations caused by the neutrons, radioactive elements are produced within the tokamak components, so choosing materials that will shed their radioactivity quickly is another priority for safe decommissioning.   Read more on CCFE .
