In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches pressures similar to the core of the sun. That process happens within a miniscule amount of space and time.

The Department of Energy’s (DOE's) Oak Ridge National Laboratory (ORNL), Type One Energy and the University of Tennessee in Knoxville are partnering to establish a world-class facility that will drive American innovation and move fusion energy closer to reality.

At 4 a.m., while most of New Jersey slept, a Princeton Plasma Physics Laboratory (PPPL) physicist sat at his computer connected to a control room 3,500 miles away in Oxford, England. Years of experience running fusion experiments in the U.S. helped guide the U.K. team through delicate adjustments as they worked together to coax particles of plasma—the fourth state of matter—to temperatures that match those found at the heart of the sun.

Researchers using China’s “artificial sun” fusion reactor have broken through a long-standing density barrier in fusion plasma. The experiment confirmed that plasma can remain stable even at extreme densities if its interaction with the reactor walls is carefully controlled. This finding removes a major obstacle that has slowed progress toward fusion ignition. The advance could help future fusion reactors produce more power.

Researchers working on China's fully superconducting Experimental Advanced Superconducting Tokamak (EAST) have experimentally accessed a theorized "density-free regime" for fusion plasmas, achieving stable operation at densities well beyond conventional limits.

Researchers say fusion reactors might do more than generate clean energy—they could also create particles linked to dark matter. A new theoretical study shows how neutrons inside future fusion reactors could spark rare reactions that produce axions, particles long suspected to exist but never observed. The work revisits an idea teased years ago on The Big Bang Theory, where fictional physicists couldn’t solve the puzzle. This time, real scientists think they’ve found a way.

Using a combination of physics and machine learning, the researchers predicted how the plasma inside a tokamak reactor would behave given a set of initial conditions.

Tokamaks are machines that are meant to hold and harness the power of the sun. These fusion machines use powerful magnets to contain a plasma hotter than the sun's core and push the plasma's atoms to fuse and release energy. If tokamaks can operate safely and efficiently, the machines could one day provide clean and limitless fusion energy.

Author(s): C. L. Jiang, W. F. Henning, B. P. Kay, and K. E. RehmFusion reactions are the most complex reaction processes during the collision of two nuclei, their cross sections spanning several orders of magnitude. The authors expand a previous analysis of heavy-ion fusion, applying a recently proposed universal function for fusion cross sections. By scaling both energy and cross sections according to characteristics of the Coulomb barrier, the authors essentially take into account the influence of the Coulomb interaction between the two nuclei as they fuse. The approach reproduces fusion excitation functions rather well, even in the energy region below the Coulomb barrier, while highlighting individual reaction characteristics as one compares many fusion systems.

In the universe, thermonuclear fusion is a common reaction: it is the source of energy for stars. On Earth, producing energy using this process is difficult due to problems with controlling the plasma emitting significant amounts of energy. Of critical importance here is the knowledge of the current state of the plasma and the power released in nuclear reactions. In the ITER reactor, this knowledge will be gathered by a sophisticated neutron flux diagnostic system.
