Model C stellarator

<p>The Model C stellarator was the first large-scale <a href="/facts/Stellarator/HXSJF0Cz">stellarator</a> to be built, during the early stages of <a href="/facts/Fusion_power/jyETSzm4">fusion power</a> research. Planned since 1952, construction began in 1961 at what is today the <a href="/facts/Princeton_Plasma_Physics_Laboratory/YEBMkkow">Princeton Plasma Physics Laboratory</a> (PPPL). The Model C followed the table-top sized Model A, and a series of Model B machines that refined the stellarator concept and provided the basis for the Model C, which intended to reach break-even conditions. Model C ultimately failed to reach this goal, producing <a href="/facts/Electron/L0KBo5cW">electron</a> temperatures of 400 eV when about 100,000 were needed. In 1969, after UK researchers confirmed that the <a href="/facts/USSR/m7wWsPto">USSR</a>'s T-3 <a href="/facts/Tokamak/kDtb8Bsw">tokamak</a> was reaching 1000 eV, the Model C was converted to the Symmetrical Tokamak, and stellarator development at PPPL ended.
