The device was the first of its kind to test the levitated dipole concept and was funded by the [[United States Department of Energy|US Department of Energy]].<ref>{{Cite web|title=Levitated Dipole Experiment|url=https://www-internal.psfc.mit.edu/ldx/|access-date=2020-06-22|website=www-internal.psfc.mit.edu}}</ref> The machine was also part of a collaboration between the [[MIT Plasma Science and Fusion Center]] and [[Columbia University]], where another (non-levitated) dipole experiment, the Collisionless Terrella Experiment (CTX), was located.<ref>{{Cite web|title=CTX|url=http://sites.apam.columbia.edu/CTX/index.html|access-date=2020-06-22|website=sites.apam.columbia.edu}}</ref> LDX ceased operations in November 2011 when its funding from the Department of Energy ended as resources were being diverted to [[tokamak]] research.<ref name="fundingcut">{{cite web|title=LDX funding canceled|url=http://www.fusenet.eu/node/216|url-status=dead|archive-url=https://web.archive.org/web/20130117084532/http://fusenet.eu/node/216|archive-date=2013-01-17|access-date=June 27, 2012}}</ref><ref name="fundingcut2">{{cite journal|last=Feder|first=Toni|year=2011|title=US narrows fusion research, joins German stellarator|journal=Physics Today|volume=64|issue=9|pages=30|doi=10.1063/PT.3.1252}}</ref>
