±¬×ߺÚÁÏ

?±¬×ߺÚÁÏ is the most complex experiment ever attempted on this planet. Its aim, to demonstrate that nuclear fusion, the power of the Sun, can give us pollution free energy that we can use for millions of years. But at the moment, it's still largely a vast building site in the Haut Provence of southern France ...

Roland Pease has been to Cadarache to see how work is progressing, and to hear of the hopes of the scientists who have dedicated their working lives to the dream.

Listen to the 30-minute documentary from the BBC World Service program Discovery .

At Cadarache (south of France), the Institute for Magnetic Fusion Research (CEA/DSM/IRFM) is modifying the Tore Supra plasma facility to become a test platform open to all ±¬×ߺÚÁÏ partners : the WEST project (acronym derived from W Environment in Steady-state Tokamak, where W is the chemical symbol for tungsten).

The goal is to equip the tokamak with an actively cooled tungsten divertor, benefitting from its unique long pulse capabilities, its high level of additional power and the unique experience of operation with actively cooled components.
