China’s ‘Artificial Sun’ Achieves Super I-Mode That Could Lead To More Stable Fusion Energy

China’s ‘Artificial Sun’ Achieves Super I-Mode That Could Lead To More Stable Fusion Energy thumbnail

China is progressing on its “artificial sun project” to develop a nearly infinite energy source. Chinese scientists working on this project have uncovered a previously unknown mode of plasma activity that may enable more reliable and efficient nuclear fusion energy production.

A breakthrough and demonstration of a new plasma operation scenario called Super I-Mode was made on the Experimental Advanced Superconducting Tokamak (EAST), according to Hefei Institutes of Physical Science, Chinese Academy of Sciences (CAS).

The EAST reactor at Hefei discovered the “Super I-mode” for the first time in December 2021 after a record-breaking 17-minute operation, reported SCMP. The findings, rigorously reviewed by peers, were published on January 6, 2023, in the international journal Science Advances.

The new high-confinement and self-organizing Super I-mode exemplifies the machine’s advancement and dependability and provides insights into how to keep the plasma functioning steadily and for an extended time.

The record-breaking run, which employed magnetic fields to heat a plasma-charged gas composed of free-moving electrons and hydrogen ions to a temperature of 70 million degrees Celsius, managed to contain high energy both at the plasma edge and farther into the plasma.

Further testing revealed that the novel mode has a high potential for use in the International Thermonuclear Experimental Reactor (ITER), according to the Chinese Academy of Sciences researchers and their collaborators from the United States, Europe, and Japan, among others.

The largest fusion reactor in the world, ITER, is currently being built in France. This is a critical breakthrough for ITER and fusion, according to physicist Richard Pitts, who oversees experiments and plasma operations at ITER.

Pitts added that the EAST tests are critical because they revealed for the first time that tokamak plasmas could be maintained and regulated for very long pulses – more than 1,000 seconds, which is equivalent to the long pulses ITER aims for in the long term.

Pitts noted numerous challenges connected with very long pulse operations, and it is quite reassuring for ITER to see that this has been accomplished, even on a considerably smaller device.

According to Song Yuntao, the study’s co-author, one of the key benefits of the super I-mode was its capacity to lessen energy loss near the plasma edge, where the superhot gas directly faced the tokamak’s heat shield.

Song explained that if we equate nuclear fusion processes to lightning bolts, researchers aim to gather as many bolts as possible in a magnetic cage and transfer the energy stably and sustainably for human use.

Song said that the new operating mode discovered on EAST allows the Chinese scientists to capture more lightning bolts while sustaining steady-state functioning for an extended period.

Why Is The New Super I-Mode Important?

Fusion is the process of two hydrogen atoms fusing to produce an atom of helium while emitting tremendous energy, which powers the sun and stars.

Scientists aim to recreate the sun’s power on Earth and want the fusion process to be well-controlled. They expect society to be fueled in a new, far more efficient, and environmentally friendly way.

One of the most promising routes towards managed nuclear fusion is through tokamaks like EAST and ITER. The challenge is still in producing high-performance plasma and confining it for long enough for the hydrogens to combine to produce net power as the sun does.

Liu Zhihong from the Institute of Plasma Physics in Hefei stated that fusion scientists employ operating parameters, or “modes,” to control the condition of the plasma. These factors include temperature and energy.

Most tokamaks today, including EAST, run in high-confinement mode or H-mode. Large reactors like ITER were made possible by H-mode, which was first detected on a tokamak in Germany in 1982. H-mode was at least 100 times more effective in confining plasma than the prior low-confinement mode.

However, a significant drawback of H-mode operation is that it might cause a sudden release of energy at the plasma edge and harm nearby materials.

To avoid harming the surfaces, scientists have recently explored the I-mode, also known as improved confinement mode, in which the fusion energy is released through a more continuous process.

But, Scientists were astonished to learn that, when compared to the I-mode, the new mode had considerably enhanced energy confinement, earning it the moniker Super I-mode. Pitts pointed out that since super I-mode was only observed on EAST, it is unclear whether ITER could use it. He added that ITER planned to operate in “advanced scenarios” akin to the EAST experiments.

“These advanced scenarios allow you to run very long plasma durations – up to 3,000 seconds on ITER. In the H-mode, ITER can only go up to about 500-second plasma duration,” Pitts said.

EAST is the first of its kind to run with pulses of 1,000 or less. Since running in 2006, the reactor has supported thousands of experiments conducted domestically and with the global fusion community.

    Hype and fluff for the techie dreamers. Yep! PRACTICAL fusion energy will soon be available. NOT!

    Just look at the pictures. The world is going to PROFITABLY build thousands of these in the next decade? Hahahahahahaha! Nothing happens if there is no profit. Nothing.

    But then, what happens to all of this when the kinetic war breaks out in Urope and Taiwan? And the West, including the US, will be struggling to survive. Suddenly countries are not paying for those over priced mechanics working on this techie dream? It becomes a rusting piece of junk.

    Reality has never been popular in techie land. When the cash stops, so does “progress”. So be it.

    Fusion power development is progressing at unprecedented rates.

    We will have to update the 30 years to a new 30 years until ready more often now.

    Peakyeast, we will likely not live to see practical fusion power other than the sun. It is always sometime in the future.

    theluckycountry,

    Like civilizations:

    “In the Study Toynbee examined the rise and fall of 26 civilizations in the course of human history, and he concluded that they rose by responding successfully to challenges under the leadership of creative minorities composed of elite leaders. Civilizations declined when their leaders stopped responding creatively, and the civilizations then sank owing to the sins of nationalism, militarism, and the tyranny of a despotic minority.” – (Encyclopedia Britannica)

    “…The idea of a totalitarian control grid is familiar to science fiction fans, but imaginative fiction stretches boundaries for artistic purposes. Utopia (including dystopia) is a form of science fiction. There are crucial aspects in the plan for a technocratic dystopia that, as fearful as it is, cannot be realized….Is this all going to be done by AI and robots? Computer networks and servers depend on complex supply chains. CPU chips are made mostly in Taiwan, memory chips in South Korea, and hard drives at several places including North America. A single factory to produce semiconductors costs over $1 billion to construct and involves technical expertise from many different fields….The elites’ version of the world where Bill and Klaus have nice things with a high tech control grid crushing everyone cannot be built in the form which they imagine. Bill and Klaus cannot possibly make all the stuff they want on their own, even with robots. Their vision does not include economic calculation….”

    ““In the Study Toynbee examined the rise and fall of 26 civilizations in the course of human history, and he concluded that they rose by responding successfully to challenges under the leadership of creative minorities ”

    Yes I agree with all that, that’s really how civilizations play out, beginning as agrarian societies of strong morals and not multicultural at all but having a distinct Us and Them mindset. Another part of the process though is Energy. All great former empires employed an energy base greater than it’s native one. Slaves, or in British case, exploiting the labor of third world nations.

    Out current civilization has been built on fossil fuel energy. A single barrel of oil contains the energy equivalent of 1000 men working for a year. Which makes sense when you consider how many men you would need to push or pull your car 1000 miles across the country. And that at 60 miles per hour too!

    Collapse of morals, corruption of morals, collapse of the food base and loss of the source of cheap energy. These are probably the main drivers of collapse of empire and we have them all. Right across the globe
