The Tokamak à configuration variable (TCV, literally "variable configuration tokamak") is a Swiss research fusion reactor of the École polytechnique fédérale de Lausanne. Its distinguishing feature over other tokamaks is that its torus section is three times higher than wide. This allows studying several shapes of plasmas, which is particularly relevant since the shape of the plasma has links to the performance of the reactor. The TCV was set up in November 1992.
