Cooperative research between the DIII-D National Fusion Facility in USA and the Institute of Plasma Physics (ASIPP) of the Hefei Institutes of Physical Science (HFIPS) in China has identified a key approach to creating plasma conditions that will be necessary for steady-state operation of ITER. This new approach shows promise in avoiding potential edge instabilities in the plasma that can pose increased plasma-material interaction challenges.

Plasma instabilities known as edge-localized modes (ELMs) are a challenge to stable operation of fusion reactors. Effective ELM control is particularly important in high-confinement, steady-state fusion plasmas such as ITER. The research at DIII-D and EAST found that maintaining high density at the edge of the plasma and a high density ratio between the pedestal bottom and top can reduce the severity of ELMs.

"Combining ELM control with high fusion performance will be critical for efficient operation of ITER and the power plants that come after it," said XU Guosheng. "These results are an important step toward practical fusion energy."

One approach to ELM control has been creating plasma conditions in which ELMs may occur, but are much smaller. Known as "grassy" ELMs, these conditions have been achieved on other devices, but often under parameters that are not suitable for large, long pulse devices like ITER. Experiments on DIII-D demonstrated a grassy ELM regime at an ITER-relevant parameters.

In lieu of an in-person ITER Business Forum this year, the ITER Organization is planning a two-day Remote ITER Business Meeting, from 6 to 7 April 2021.

The purpose is the same: to inform the business community about upcoming contract opportunities at ITER and to create the opportunity for businesses to meet and plan together through B2B meetings.

It will also be possible to meet project specialists in one-to-one Skype sessions on a variety of topics, including how to set up a business in the south of France with the Welcome Around ITER network and specific contract opportunities (Hot Cell, maintenance services, Tritium Plant, remote maintenance, and European contract opportunities through Fusion for Energy).  

To participate, fill out your pre-registration form on this website: https://www.iter.org/ribm2021. The deadline is 6 April 2021.

The EUROfusion consortium has announced the award of 16 fusion energy research grants across Europe for the development of innovative new ideas and techniques.

EUROfusion makes grants available on behalf of the European Commission's Euratom program. In its meeting on 3 March 2021, the General Assembly of EUROfusion selected 16 out of 72 Enabling Research proposals based on the recommendations of the scientific boards in four research categories. EUROfusion will invest a total of € 20.1 million in these projects, of which € 9.9 million comes as a contribution from the consortium.

The four research categories are: materials, theory and modelling, technology and systems, and inertial fusion.
