===Later experiments===
Although it became clear that TFTR would not reach break-even, experiments using tritium began in earnest in December 1993, the first such device to move primarily to this fuel. In 1994 it produced a then world-record of 10.7 megawatts of fusion power from a 50-50 D-T plasma (exceeded at [[Joint European Torus|JET]] in the UK, which generated 16MW from 24MW of injected thermal power input in 1997). The two experiments had emphasized the alpha particles produced in the deuterium-tritium reactions, which are important for self-heating of the plasma and an important part of any operational design. In 1995, TFTR attained a world-record temperature of 510 million °C - more than 25 times that at the center of the sun. This later was beaten the following year by the JT-60 Tokamak which achieved an ion temperature of 522 million °C (45 keV).<ref>{{Cite web|url=https://jopss.jaea.go.jp/search/servlet/search?5017810&language=1|title = Plasma physics found in JT-60 tokamak over the last 20 years}}</ref> Also In 1995, TFTR scientists explored a new fundamental mode of plasma confinement -- [[enhanced reversed shear]], to reduce plasma turbulence.<ref>{{cite web |url=http://www.pppl.gov/Tokamak%20Fusion%20Test%20Reactor |title=Tokamak Fusion Test Reactor |access-date=2014-10-30 |archive-date=2014-10-30 |archive-url=https://web.archive.org/web/20141030220522/http://www.pppl.gov/Tokamak%20Fusion%20Test%20Reactor |url-status=dead }}</ref>

TFTR remained in use until 1997. It was dismantled in September 2002, after 15 years of operation.<ref>{{cite web |url=http://www.princeton.edu/main/news/archive/S01/16/32S00/index.xml#top |title=Princeton University - Tokamak Fusion Test Reactor removal successfully completed |website=www.princeton.edu |url-status=dead |archive-url=https://web.archive.org/web/20130423170127/http://www.princeton.edu/main/news/archive/S01/16/32S00/index.xml |archive-date=2013-04-23}}</ref>

It was followed by the [[National Spherical Torus Experiment|NSTX]] spherical tokamak.<ref>http://www.pppl.gov/Tokamak%20Fusion%20Test%20Reactor {{Webarchive|url=https://web.archive.org/web/20141030220522/http://www.pppl.gov/Tokamak%20Fusion%20Test%20Reactor |date=2014-10-30 }} ("In addition to meeting its physics objectives, TFTR achieved all of its hardware design goals")</ref>
