The Tokamak de Fontenay-aux-Roses (TFR) was the first French tokamak, built in a research centre of the French Atomic Energy Commission (CEA) in Fontenay-aux-Roses, a commune in the southwestern suburbs of Paris, France. Roughly the same size as the contemporary Soviet T-3 and American , but had a larger internal plasma volume and a much more powerful power supply that drove plasma currents up to 400,000 Amps for as long as half a second. Completed in 1973, it remained the world's most powerful tokamak until 1976 when it was surpassed by the Princeton Large Torus.

Mis en service de 1973 à 1986 à Fontenay-aux-Roses dans les Hauts-de-Seine par le Commissariat à l'énergie atomique et aux énergies alternatives, ce centre de recherche expérimentale était à l'époque et jusqu'en 1976 le tokamak le plus puissant au monde. Le physicien Paul-Henri Rebut en dirigea la conception. Le tokamak de Tore Supra à Cadarache lui succéda en 1988. (fr)

- The Tokamak de Fontenay-aux-Roses (TFR) was the first French tokamak, built in a research centre of the French Atomic Energy Commission (CEA) in Fontenay-aux-Roses, a commune in the southwestern suburbs of Paris, France. Roughly the same size as the contemporary Soviet T-3 and American , but had a larger internal plasma volume and a much more powerful power supply that drove plasma currents up to 400,000 Amps for as long as half a second. Completed in 1973, it remained the world's most powerful tokamak until 1976 when it was surpassed by the Princeton Large Torus. Among the major discoveries made on TFR was the concept of "disruptions", potentially damaging events that eject the plasma from the center and lead to an event known as "runaway electrons". In 1975, such an event burned holes through the vacuum vessel, requiring extensive repairs. It was followed by Tore Supra at Cadarache. (en)
