In a recent experiment, researchers at the Max Planck Institute for Plasma Physics sustained a stable plasma reaction in the ...

Thanks to new observations, both the helium and deuterium ratios are now measured, confirming the Big Bang once again. The early Universe was full of matter and radiation, ...

More but calculable amounts of deuterium, helium-3, and lithium-7 left over as well. Until the latest results from the LUNA collaboration, step 2a, where deuterium and a proton fuse into helium-3 ...

Once they blasted deuterium gas with protons and measured the resulting amount of helium, they had to plug that value into existing and more concretely understood numbers for the background ...

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

There are similar discrepancies between BBN theory and the primordial helium-4 abundance. Unlike the deuterium abundance, the amount of helium-4 produced in the BBN model increases very slowly as a ...

Deuterium-tritium fusion also creates radioactive byproducts that have to be disposed of periodically. Helium 3’s main advantage as a fusion fuel is that it creates little or no radioactive ...

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 ...

Helion Energy Kulcinski says D-helium-3 (Deuterium-Helium3 ) could be the stopgap step between deuterium-tritium and p-B11. The reaction requires a temperature of several hundred million degrees, in ...

In the series of chain reactions shown, protons and neutrons fuse to form deuterium, then these deuterium nuclei fuse to form helium nuclei. Anne-Katherine Burns A clue in helium.

The team has also demonstrated sympathetic cooling with helium-3 ions and is now applying the technique to other species, including diatomic molecules made of hydrogen and deuterium. “Helium ions are ...
