The gas centrifuge for uranium enrichment.
The possibility of using centrifuges to
separate isotopes was raised shortly after isotopes
were discovered in 1919. The first experiments using
centrifuges to separate isotopes of uranium (and
other elements) were successfully carried out on a
small scale prior to and during World War II, but
the technology only became economically competitive in the 1970s. Today, centrifuges are the most
economic enrichment technology, but also the most
