Scientists just recreated a 1938 experiment that could rewrite fusion history

SMRTR summary

Los Alamos researchers have replicated a 1938 experiment by University of Michigan physicist Arthur Ruhlig, confirming his observation of deuterium-tritium (DT) fusion. Using modern equipment, the team validated Ruhlig's conclusion that DT fusion occurs with high probability. This discovery has significantly impacted fusion technologies, including efforts at the National Ignition Facility. The research highlights the origins of DT fusion knowledge and acknowledges Ruhlig's important contribution to the field.
