Editor’s observe: That is a part of a sequence profiling researchers advancing science with excessive efficiency computing. 

Earlier than she entered highschool, Ge Dong wished to be a physicist like her mother, a professor at Shanghai Jiao Tong College.

“She stated clear vitality was actually essential for sustaining humanity, she talked about it lots,” stated Ge Dong (above at age two along with her mother).

At 32, she’s following that dream at a startup that hopes to seek out — with the assistance of HPC and AI — a business path to nuclear fusion.

Pioneering AI in Physics

In 2014, her life’s work took her greater than 7,000 miles from her Shanghai house to Princeton College’s prestigious plasma physics lab, the place she earned a Ph.D.

Her doctoral thesis was constructed on advances by Princeton colleagues. They had been the primary to make use of AI to foretell plasma disruptions that might trigger a fusion reactor to fail.

Ge Dong’s work make clear how the perimeters of plasma, hotter than the floor of the solar, behave inside a prototype fusion reactor, a donut-shaped enclosure referred to as a tokamak.

Later, she spent greater than a 12 months working along with her colleagues and NVIDIA consultants to create with NVIDIA Omniverse a digital twin to indicate how plasma circles inside a tokamak. Utilizing AI, the trouble slashed the prices of a simulation based mostly on conventional number-crunching strategies.

The outcomes might assist engineers construct controls that hold superheated plasma safely inside tomorrow’s energy crops, dashing the arrival of the clear vitality supply.

A Pivotal Dialog

In the course of the Covid lockdown, Ge Dong returned to Shanghai to work at home. There, in 2021, a pivotal dialog with a pal, Zhou Yang, led to the choice to co-found Vitality Singularity, a startup with an formidable plan.

Yang stated he wished to construct a tokamak. When she dismissed the multibillion-dollar concept, he gave an in depth breakdown of a plan that may price far much less.

Then he defined why he wished to take an strategy, fashionable amongst researchers, of utilizing high-temperature superconducting magnets to manage the plasma. Though he studied a separate department of physics, he may clarify the rationale all the way down to its basic equations.

After their discuss, “I used to be so excited, I didn’t sleep the entire evening,” she stated of the daring plan.

A couple of months later, they joined three others to launch the corporate.

A Recent Problem for AI

Studying the right way to construct and management the highly effective, however fragile magnets is the startup’s chief technical problem. The crew is popping to HPC and AI to seek out its approach.

“It’s an entire new space of analysis that’s ripe for the form of statistical evaluation AI can speed up to ship the best and lowest price strategy,” she stated.

The startup is already designing its prototype on an NVIDIA-accelerated server in its workplace.

“We’ve been utilizing NVIDIA GPUs for all our analysis, they’re probably the most essential instruments in plasma physics as of late,” she stated.

The Subsequent Technology

The work may be all-consuming. Nobody on the crew has had time to take a look at the free fitness center of their constructing. And it’s been some time since Ge Dong had a very good sport of badminton, a favourite pastime.

However she stays upbeat. Inside a decade, somebody will present the best way to harnessing nuclear fusion, and it could possibly be her firm, she stated.

Ge Dong is bound her five-year-old daughter will see her intense ardour for plasma physics. However when it comes time to decide on a profession, she might hear a distinct calling in a fusion-powered world.
