Two Los Alamos Laboratory scientists discovered Arthur Ruhlig’s major contributions to fusion physics, and they did so ...

A Los Alamos collaboration has replicated an important but largely forgotten physics experiment: the first deuterium-tritium ...

Scientists have replicated a forgotten but crucial experiment that took place in 1938. The first-ever triton-deuterium ...

In DT fusion, the majority of the energy is carried away by neutrons for electricity production, ... the neutron spectrum data deviated significantly from hydrodynamic predictions, ...

In particular, deuterium-tritium fusion makes an intense flux of high-energy neutrons, which collide with the nuclei of atoms in the metal walls and cladding, causing tiny spots of melting.

Hartouni and colleagues collected isotropic neutron data using five time-of-flight spectrometers positioned at different points around the fusion target. After plotting the results, they were able to ...

Apart from neutron-capturing technologies and high-tech materials, fusion scientists and engineers still need to figure out how to close the deuterium-tritium fuel cycle. While deuterium is ...

How the IFMIF-DONES facility could look (Image: IFMIF-DONES) The ITER Organisation noted the high kinetic energy of fast neutrons produced in a deuterium-tritium fusion reaction is converted into heat ...
