===Fusor===
The [[Fusor|Farnsworth fusor]] is an apparatus designed by Farnsworth to create nuclear fusion. Unlike most controlled fusion systems, which slowly heat a magnetically confined [[Plasma (physics)|plasma]], the fusor injects high-temperature [[ion]]s directly into a reaction chamber, thereby avoiding a considerable amount of complexity.{{fact|date=July 2022}}

When the Farnsworth fusor was first introduced to the fusion research world in the late 1960s, the fusor was the first device that could clearly demonstrate it was producing fusion reactions at all.  Hopes at the time were high that it could be quickly developed into a practical power source. However, as with other fusion experiments, development into a power source has proven difficult.  Nevertheless, the fusor has since become a practical [[neutron source]] and is produced commercially for this role.<ref name="fusor3"/><ref name="fusor2">{{cite journal | url = http://physicsworldarchive.iop.org/index.cfm?action=summary&doc=20/3/phwv20i3a18@pwa-xml&qt=the%20secret%20world%20of%20amateur%20fusion
