MIIFED-IBF 2016: Sign up now!

From 8 to 11 February, the Monaco-ITER International Fusion Energy Days (MIIFED) will combine with the ITER Business Forum (IBF) to create a single event dedicated to ITER progress and upcoming business opportunities.

Over 400 participants from 200 companies have already registered for MIIFED-IBF 2016, which will be the sole event dedicated to industrial opportunities at ITER in 2016. The three-day conference will also feature an industrial and R&D exhibition.

It is still possible to schedule one-to-one meetings (B2B and B2C). These networking opportunities facilitate the exploration of partnership opportunities in the context of the technological challenges that lie ahead for ITER. To schedule a one-to-one meeting or to ask for business appointments (based on company profiles), please consult the pages dedicated to registered participants here.

In combining ITER Business Forum with the MIIFED international event, the MIIFED-IBF2016 Conference is specifically designed to support enhanced communication with industry and ensure that ITER procurement practices will be efficient and supportive of its industrial partners. It also aims to facilitate productive interaction between industry and fusion laboratories from the seven ITER Members and to foster collaboration between those actors, especially in technical areas where strong cooperation is required.

See the conference website for more information or to register now.

Mira supercomputer gives new "edge" to fusion research

Using Mira, physicists from Princeton Plasma Physics Laboratory (PPPL) have uncovered a new understanding about electron behaviour in edge plasma. Based on this discovery, improvements were made to a well-known analytical formula that could enhance predictions of and, ultimately, increase fusion power efficiency.

Principal investigator C.S. Chang, head of the U.S. SciDAC-3 Partnership for Edge Physics Simulation headquartered at PPPL, and co-investigator Robert Hager recently gained new insight into the properties of a self-generating electrical current that boosts power in a tokamak fusion reactor, based on simulations run on the 10-petaflop IBM Blue Gene/Q supercomputer Mira located at the Argonne Leadership Computing Facility in the US.

To develop the best predictive tools for ITER (and, by extension, other experimental fusion reactors), research teams are using high-performance computing to resolve the behaviours of fusion plasma across the many spatial scales that impact reactor efficiency and plasma stability.

Running on more than 260,000 Mira processing cores with excellent scalability, the latest XGCa plasma edge simulations revealed electron behaviours related to edge bootstrap current that are not accurately predicted for present-day tokamak geometry by the well-known Sauter formula, which is used to calculate values for the bootstrap current.

"Mira allows running simulations of larger tokamaks at ITER's scale, and modeling at much higher particle counts more accurately represents the electron populations in the plasma," said Tim Williams, Argonne computational scientist.
