There are other entities in the race, including Germany's Wendelstein 7-X stellarator and the now-inactive but still operational Alcator
C-Mod tokamak at MIT.
The team set a new world record for plasma pressure in an Alcator
C-Mod tokamak nuclear fusion reactor.
C-Mod is a relatively small tokamak experiment at MIT's Plasma Science and Fusion Center.
Many advances in plasma performance in the last decade have been achieved through improved wall conditioning, for example, boronization in Alcator
C-Mod (17) [24, 25] and DIII-D (18) [26, 27], JT-60U , TEXTOR (19) , START20 , and, most recently, the best performance has occurred on MAST21  and NSTX (22) .
He is professor of nuclear science and engineering at the Massachusetts Institute of Technology, where he is also coprincipal of the Alcator
Project in the Plasma Science and Fusion Center.

But Bruno Coppi of the Massachusetts Institute of Technology argues that experimentation with deuterium and helium-3 could be done in some current mainstream experiments--MIT's Alcator
, for example.
The MIT team at the Alcator
C-Mod tokamak nuclear fusion reactor set a new world record for plasma pressure at 2.05 atmospheres - 15 percent higher than the previous C-Mod record of 1.77 atmospheres set in 2005.
The document indicates that the NDCX-II at Lawrence Berkeley National Laboratory would not be operated in FY 2015 and that Alcator
C-Mod at MIT would close in late FY 2016.
He and his MIT team designed, built, and operate the Alcator
C-Mod tokamak, whose plasmas, with temperatures reaching beyond 50 million degrees Celsius, are prototypical of a future fusion reactor.
The Bill provides $22,260,000 for operations and research on the Alcator
C-Mod at MIT.
