A team around physicist Jong-Kuy Park of the Princeton Plasma Physics Laboratory (PPPL) has made significant progress in tackling a common instability in fusion plasmas called edge localized modes or ELMs.

Bursts of ELMs, energy releases likened to solar flares, can slam into the walls of a tokamak and potentially cause damage. In order to prevent these EMLs from occurring, scientists produce small magnet ripples called resonant magnetic perturbations, or RMPs, that disturb the plasma and release excess pressure. As there are many potential magnetic distortions, it is a difficult task to create the right kind of beneficial distortions.

Park's team of scientists from the United States and the National Fusion Research Institute (NFRI) in Korea has "successfully predicted the entire set of beneficial 3D distortions for controlling ELMs without creating more problems," says a PPPL .

The predictions were validated at the Korean Superconducting Tokamak Advanced Research (KSTAR) facility. Its advanced magnetic controls for generating precise 3D distortions made KSTAR the ideal testing device.

The research findings, published as a in Nature Physics, will be important for ������app--a device that will employ dedicated magnets to produce 3D distortions to control ELMs.

The Culham Centre for Fusion Energy (CCFE) is partnering with a group of leading universities to advance understanding of one of the hottest topics in fusion research: turbulence in tokamak plasmas.

The £5 million-plus research program, funded by the Engineering and Physical Sciences Research Council (), will be led by a consortium of universities with a strong fusion focus—York, Oxford, Strathclyde and Warwick—and will work in partnership with Culham.

A tokamak operates by using a strong magnetic field to hold the hot fusion fuel—which is in the plasma state—away from the reactor walls. In practice the plasma in tokamak experiments is highly turbulent, and this turbulence increases the loss of heat and particles, degrading the fusion performance. If the turbulence can be reduced, this could open the way to more compact or higher fusion power reactors.

As part of the new initiative, scientists will study how well the magnetic field can confine the plasma in CCFE's new spherical tokamak. They will also seek to shed further light on the properties of an insulating region that exists at the edge of most tokamak plasmas, including , called the pedestal region. This narrow region suppresses the loss of heat and fuel from the plasma, helping to raise the core pressure closer to fusion conditions. The more insulating the pedestal, the higher the central plasma pressure.

At the core of ������app's neutral beam heating system is a novel high-frequency ion source that has been under development for years at the Max Planck Institute for Plasma Physics (IPP) in Garching, Germany. In recent results that are significant for ������app, IPP's ELISE test rig has achieved the ion current required by ������app in hydrogen for 1,000 seconds.

Neutral beam injection relies on high-speed, high energy atoms that penetrate deep into the plasma and transfer their energy to plasma particles by means of collision. The large plasma volume at ������app will impose new requirements on this proven method of injection: the particles will have to move three to four times faster than in previous systems in order to penetrate far enough into the plasma, and at these higher rates the positively-charged ions become difficult to neutralize.

At ������app, for the first time, a negatively-charged ion source has been selected, based on the development of several generations of prototype negative ion sources at IPP.

Since 2009 IPP's ELISE test rig—half the size of what is projected for ������app—has been a valuable source of experimental data as it has advanced step by step to new orders of magnitude. In the most recent report, ELISE was able to produce a stable, homogenous negative ion beam for 1,000 seconds at ������app current strength.

In addition to further work on ELISE, IPP will be collaborating with teams at ������app's Neutral Beam Test Facility, where the full-scale ������app-scale negative ion source SPIDER was commissioned earlier this year.

In the latest episode of the science and engineering podcast series Omega Tau, producer Markus Völter speaks with Pierre Bauer, a superconductor engineer at ������app, about superconductivity and its uses.

The listener is first taken back in time to hear about the discovery of superconductivity in 1911, when scientists were trying to liquefy helium in their quest to understand the behavior of metals at very low temperatures. Today, superconductivity is associated with the high-performance magnets used in nuclear fusion reactors, in particle colliders, for magnetic levitation in modern train systems, and also for medical magnetic resonance imaging.

Superconductivity was first observed in mercury; since then, research has resulted in the identification of better materials for low-temperature conductors such as niobium, which is used in ������app's niobium-titanium and niobium-tin superconductors.

Völter and Bauer touch on many more issues related to superconductivity in this episode that lasts almost three hours. It is not the first time that ������app has featured prominently in the podcast series. In October 2014, Omega Tau spoke with ������app's Richard Pitts on the physics and the engineering challenges of the project.

One of the most flexible and highly instrumented fusion research reactors in the world is undergoing major enhancements that will pave the way to future fusion power plants.

The DIII-D National Fusion Facility is the largest magnetic fusion experiment in the United States. In May, work began on a series of machine enhancements that will make it possible to commence new studies of the physics of future fusion reactors. That will help scientists understand how to achieve high fusion power in the ������app and how to sustain such regimes indefinitely in the fusion power plants that will follow ������app.

The planned year-long activity will enhance DIII-D systems by adding increased and redirected particle beams and radio frequency systems to drive current and sustain the plasma in a so-called "steady state." The improvements will also expand capabilities with the installation of new microwave systems to explore burning-plasma-like conditions with high electron temperatures. This will allow researchers to explore how to achieve higher pressure and temperatures while increasing control of the plasma, conditions critical to sustained fusion operation.

The first plasma pulse for almost 18 months took place inside of the JET tokamak in early May.

The machine—the largest and most powerful tokamak in operation today—has been undergoing a revamp to act as a testbed for ������app technologies and plasma operating scenarios. JET is now equipped with an ������app-like beryllium and tungsten wall to study material-plasma interactions, additional heating power, and the ability to handle tritium. Experiments with tritium at JET—the first since the 1990s—will act as an important "dress rehearsal" in preparation for fusion operation at ������app.

Although not a full fusion plasma, achieving the 1.2 mega amp pulse is a key part of completing the JET restart and getting ready for further commissioning of the machine. The first experiments are expected to take place this year.
