DOE News:
SAN DIEGO, Calif. The U.S. Department of Energy (DOE) announced Monday $14 million in awards to 10 universities across the country to pursue fusion energy research at the DIII-D National Fusion Facility in San Diego, Calif.
A major goal of the research is to develop and test innovative methods for understanding and sustaining high-temperature fusion plasmas, a key enabling step towards making fusion a virtually limitless source of practical energy.
The projects range from computer simulations of the complex dynamics of fusion plasmas to deployment of diagnostic devices to techniques for understanding and controlling plasmas relevant to the international ITER experiment under construction in France. All of the projects will allow university researchers to apply work done at their home institutions in a realistic fusion environment at DIII-D, the largest magnetic fusion research facility in the U.S.
“Our university collaborators are a critical part of the work we do at DIII-D, as well as the broader U.S. fusion community,” said Wayne Solomon, deputy director of DIII-D. “By supporting university research, DOE helps to attract the best minds in fusion to advance the state of the art for the entire field and bring closer the realization of sustainable energy from fusion.”
DIII-D, which General Atomics operates as a national user facility for DOE’s Office of Science, hosts researchers from more than 100 institutions across the globe, including 40 universities. The heart of the facility is a tokamak that uses powerful electromagnets to produce a doughnut-shaped magnetic bottle for confining a fusion plasma. In DIII-D, plasma temperatures more than 10 times hotter than the Sun are routinely achieved. At such extremely high temperatures, hydrogen isotopes can fuse together and release energy.

The 10 projects funded Monday by the Office of Fusion Energy Sciences within DOE’s Office of Science strongly support DIII-D’s mission to inform ITER design and operations while preparing the physics basis for future fusion facilities seeking to capitalize on the knowledge generated by ITER on the path to fusion energy.
One of the projects is led by University of California San Diego (UCSD) researcher Jose Boedo, who is working with his students and post-doctoral researchers to understand the physics of how a 100-million-degree plasma can interface with the physical boundaries of the tokamak without damaging the vessel.
Boedo said his students benefit from working on a world-class facility like DIII-D, and invariably some of them are inspired to take up the cause of harnessing fusion as a nearly limitless source of energy.
“This is a unique opportunity for them and something that only happens to a very small percentage of physics students,” said Boedo, who has been a DIII-D collaborator for more than 20 years. “They get to have this tremendous experience and work on something that is truly important for the future of humankind. Very few people in the world get to have this type of opportunity.”
In addition to UCSD, the other universities that received awards were the University of Wisconsin, Madison; Princeton University; University of California, Los Angeles; University of California, Irvine; Purdue University; Massachusetts Institute of Technology; Columbia University; Lehigh University; and Auburn University.
