Scientists achieve 'world first' by heating plasma to multimillion degree temperatures: 'Helping to unlock the mysteries of the cosmos'
A research team in Germany recently achieved what it called "a world first in fusion research," exciting the clean energy community, Interesting Engineering reported. The research team is part of the world's largest stellarator facility, Wendelstein 7-X (W7-X), where scientists have been hard at work developing a more efficient way to generate fusion energy. And now, they've finally achieved their goal, generating high-energy helium-3 ions for the first time. Nuclear fusion is the process of using force to merge two atomic nuclei. The act of combining these nuclei results in a tremendous release of energy, which provides a great deal of power that can be used for everything from fuel alternatives to electricity on a commercial scale. Fusion is a clean and naturally occurring means of energy generation; in fact, it's the primary type of power and reaction that creates the stars. And it doesn't generate polluting emissions the way other fuel sources do, appealing to climate advocates. Therefore, the more we can scale our usage of fusion, the cleaner and less overheated our planet's atmosphere will be. For fusion to happen, the process must be made more efficient. Fusion occurs inside a superheated plasma, which is kept at multimillion-degree temperatures. Traditionally, this fusion results in high-energy "alpha particles" (helium-4 nuclei), but those particles can be prone to escape, which can cool the plasma and halt the entire process. That's why the team focused on generating smaller, lower-energy particles, which could maintain the fusion process in a more manageable way. They did this using ion cyclotron resonance heating (ICRH). As Interesting Engineering explained, ICRH entails sending electromagnetic waves into plasma at "the specific frequency at which helium-3 ions naturally orbit around the magnetic field lines" in order to help the particles absorb energy. "This is similar to pushing a child on a swing: to be effective, each push must be precisely in tune with the swing's natural frequency — in other words, it must be in resonance," the scientists wrote in their press release. "This is the first time that high-energy helium-3 ions have been produced in a stellarator using ion cyclotron resonance heating (ICRH): a world first in fusion research." Researchers highlighted how the findings will also help them better understand how the sun works, as these same resonance processes used at W7-X may occur in nature. "These findings show that fusion science is not only shaping the future, but also helping to unlock the mysteries of the cosmos around us," the press release concluded.

Scientists Smash Nuclear Fusion Record, Igniting Hope For Limitless Clean Energy
Scientists in Germany have taken a giant leap towards producing near-limitless, clean energy using nuclear fusion -- the same fiery reaction that takes place in the core of the Sun. Using the Wendelstein 7-X nuclear fusion reactor, the researchers managed to sustain the fusion experiment for an impressive 43 seconds, smashing the previous records, according to a report in LiveScience. Developing nuclear fusion for energy requirements has long been a goal of scientists but reaching temperatures over 100 million degrees Celsius and sustaining its long-term operation has always proved a challenge. Moreover, current reactor concepts consume more energy than they are able to produce. However, using the machine with extremely low-density and electrically charged hydrogen gas as fuel, scientists managed to achieve the breakthrough. Wendelstein 7-X, officially called a 'stellarator', is a type of fusion device that confines hot, charged gas, known as plasma, with powerful external magnets controlling it. On May 22, plasma inside Wendelstein 7-X was raised to over 20 million Celsius, reaching a peak of 30 million Celsius. It also reached a new record high triple product, a key metric for the success of fusion power generators. The triple product is a combination of the density of particles in the plasma, the temperature required for these particles to fuse, and the energy confinement time. "The new record is a tremendous achievement by the international team. Elevating the triple product to tokamak levels during long plasma pulses marks another important milestone on the way toward a power-plant-capable stellarator," said Thomas Klinger, Head of Operations at Wendelstein 7-X. Notably, the highest values for the triple product were achieved by the Japanese Tokamak JT60U (decommissioned in 2008) and the European Tokamak facility JET in Great Britain (decommissioned in 2023). Holy grail Scientists regard nuclear fusion as the holy grail of energy. It is what powers our Sun as atomic nuclei are merged to create massive amounts of energy, which is the opposite of the fission process used in atomic weapons and nuclear power plants, where the heavy atom is split into multiple smaller ones. Last year, the Experimental Advanced Superconducting Tokamak (EAST) fusion energy reactor, dubbed China's 'artificial sun', sustained plasma for a whopping 1,000 seconds, breaking the 403-second record it set in 2023. Unlike fission, fusion emits no greenhouse gases and carries less risk of accidents or the theft of atomic material. By mimicking the natural reaction of the sun, scientists are hoping that the technology may help harness near-unlimited amounts of energy and help battle the energy crisis, as well as power humanity's exploration beyond the solar system

Nuclear fusion record smashed as German scientists take 'a significant step forward' to near-limitless clean energy
When you buy through links on our articles, Future and its syndication partners may earn a commission. A recently concluded experimental campaign at the Wendelstein 7-X stellarator at the Max Planck Institute for Plasma Physics (IPP) in Greifswald, Germany has smashed previous fusion records and set a new benchmark for reactor performances. Nuclear fusion offers a tantalizing promise of unlimited clean energy. By smashing together isotopes (or different versions) of hydrogen at incredibly high temperatures, the resulting superheated plasma of electrons and ions fuses into heavier atoms, releasing a phenomenal amount of energy in the process. However, while this fusion reaction is self-sustaining under the extraordinary temperatures and pressures within stars, recreating these conditions on Earth is a huge technical challenge — and current reactor concepts still consume more energy than they are able to produce. Stellarators are one of the most promising reactor designs, so named for their mimicry of reactions in the sun. They use powerful external magnets to control the high-energy plasma within a ring-shaped vacuum chamber and maintain a stable, high pressure. Unlike simpler tokamak reactors — which pass a high current through the plasma to generate the required magnetic field — stellarators' external magnets are better at stabilizing the plasma through the fusion reactions, a feature that will ultimately be necessary when translating the technology to commercial power plants. In the recent experiments, the W7-X stellarator outperformed previous benchmarks set by the decommissioned tokamak reactors JT60U in Japan and JET in the UK, especially over how long the plasma can be sustained. Related: Nuclear fusion could be the clean energy of the future Most notably, the international team revealed that the reactor had reached a new record high triple product — a key metric for the success of fusion power generators. The triple product is a combination of the density of particles in the plasma, the temperature required for these particles to fuse, and the energy confinement time (a measure of how well the thermal energy is held by the system). A certain minimum value called the Lawson criterion marks the point at which the reaction produces more energy than it uses and becomes self-sustaining, so a higher triple product indicates a more efficient reaction. "The new record is a tremendous achievement by the international team," said Thomas Klinger, Head of Operations at Wendelstein 7-X and Head of Stellarator Dynamics and Transport at IPP in a statement. "Elevating the triple product to tokamak levels during long plasma pulses marks another important milestone on the way toward a power-plant-capable stellarator." Key to the success of this latest milestone was the development of a new fuel pellet injector that combined continuous refueling of the reactor with pulsed heating to maintain the required plasma temperature. Over a 43-second period, 90 frozen hydrogen pellets were fired into the plasma at up to 2,600 feet (800 metres) per second, roughly the speed of a bullet. Pre-programmed pulses of powerful microwaves heated the plasma, which reached a peak temperature of 30 million degrees C, and this coordination between the microwave pulses and the pellet injection crucially extended how long the plasma could be stably maintained.

How and where is it stored? —Just a fraction of the hydrogen hidden beneath Earth's surface could power Earth for 200 years, scientists find This same campaign also increased the energy turnover of the reaction to 1.8 gigajoules over a six-minute run, smashing the reactor's previous record of 1.3 gigajoules from February 2023. Energy turnover is a combination of the heating power and plasma duration of a fusion reactor and an indication of the reactor's ability to sustain the high-energy plasma. It is therefore another crucial parameter for future power plant operation. The new value even exceeds the record achieved by the Experimental Advanced Superconducting Tokamak (EAST) in China earlier this year, further evidencing stellarators' potential. "The records of this experimental campaign are much more than mere numbers. They represent a significant step forward in validating the stellarator concept—made possible through outstanding international collaboration," summarized Robert Wolf, Head of Stellarator Heating and Optimization at IPP in statement.
