Google has agreed to purchase 200 megawatts of fusion energy from Commonwealth Fusion Systems (CFS). That's assuming, of ...

Modern re-run shows that Arthur Ruhlig’s conclusions, which probably influenced early thinking about fusion energy, were ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Deuterium (heavy hydrogen), for instance, has one proton and one neutron in its nucleus. When two deuterium nuclei are fused together, they form a helium nucleus (two protons and two neutrons ...

They have discovered that gamma rays, produced during the deuterium-tritium nuclear reaction, can serve as a precise and alternative means of measuring the power output of new fusion reactors.

But there are other options, including hydrogen-boron and deuterium-helium-3, a form of helium with only one neutron instead of the more common two. To get deuterium and tritium to fuse, ...

Notably, the method used by this team to measure the gamma-ray-to-neutron branching ratio could also be adapted and applied to other fusion reactions that do not produce neutrons, such as proton ...

Deuterium/helium-3 fusion creates far fewer radioactive neutrons. However, creating and sustaining such a reaction is much more challenging than conventional deuterium/tritium.

The researchers had previously measured muonic helium-4 and, a few years ago, the atomic nucleus of muonic hydrogen and deuterium. Muonic helium-3: Twice as slimmed-down.

Theoretically, a deuterium/helium-3 fusion reaction would liberate 164.3 megawatt-hours of energy per gram of helium-3 – and crucially, neither the helium-3 or its reaction products are ...
