Researchers directly simulate the fusion of oxygen and carbon nuclei

U.S. Department of Energy Office of Science

The U.S. Department of Energy Office of Science (DOE-SC) posted a highlight titled “Researchers directly simulate the fusion of oxygen and carbon nuclei” about a study that measured the probability of fusing oxygen isotopes with carbon nuclei as a function of energy. The authors of the publication are from the Facility for Rare Isotope Beams and Indiana State University. Each year, scientists publish thousands of research findings in the scientific literature. About 200 of these are selected annually by their respective program areas in DOE-SC as publication highlights of special note.

In a new study, researchers from the Facility for Rare Isotope Beams and Indiana State University have performed the most comprehensive computation to-date of fusion reaction processes. The study used supercomputing facilities to perform thousands of time-dependent simulations. The work is published in the journal Physical Review C.

Stellar reaction recreated in the lab

Scientists at the Department of Energy’s (DOE) Oak Ridge National Laboratory and Michigan State University (MSU) have reproduced in a laboratory one of the specific reactions that occurs when a neutron star gobbles up mass from a nearby companion star. This effort has collaborators from nine institutions across three countries, including the Facility for Rare Isotope Beams, a DOE Office of Science user facility that MSU operates. In their lab environment, the team of researchers used the world’s highest-density helium jet to recreate the nuclear reaction. The experiment produced the same physics on Earth that occurs in outer space.

Knowledge (gained from) gaps

University of Tennessee Knoxville

Ian Cox is proof that you don't always have to travel far to go a long way. He grew up in Knoxville, graduated from Hardin Valley Academy, and came to the University of Tennessee Knoxville on a physics scholarship. Now he's finishing a PhD in nuclear physics with Professor Robert Grzywacz and is first author on a Physical Review Letters publication detailing a new approach to understanding exotic nuclei. Researchers from 13 universities and five national laboratories collaborated on this investigation at the Facility for Rare Isotope Beams (FRIB), a premiere research hub at Michigan State University. 

The Michigan State University Board of Trustees authorized construction of a high-bay addition to the west end of the Facility for Rare Isotope Beams (FRIB). The addition will triple the testing capacity of the current chip-testing facility by providing two additional user vaults. The K500 Chip Testing Facility at FRIB will help meet the current national shortfall of testing capacity for advanced microelectronics, including those used for commercial spaceflight, wireless technology, and autonomous vehicles.
