Princeton lab identifies potential shortcut to achieve nuclear fusion ignition

Scientists at the United States Department of Energy's Princeton Plasma Physics Laboratory have identified a potentially much more efficient method to achieve nuclear fusion ignition, ScienceDaily reported. Fusion ignition is a critical milestone where a fusion reaction becomes self-sustaining. The new approach reverses traditional methods by heating the plasma first and then increasing its density.

Nuclear fusion occurs when two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process. Devices designed to harness this reaction for electrical power generation are known as fusion reactors. [2]

According to ScienceDaily, theoretical calculations indicate that this reversed sequence could help future reactors achieve self-sustaining fusion using far less input energy. The strategy is also designed to avoid hidden operational problems that typically make ignition harder to reach. [1]
