JET Back in Operation

July 9, 2008

The Joint European Torus (JET) resumed operations in April 2008 after shutting down in April 2007 for upgrades and refurbishment. JET holds the world record for the production of fusion power in a magnetic confinement device. JET is considered to be a prototype for ITER.

A number of new capabilities were added to JET during the shutdown, including an ITER-like Ion Cyclotron Resonance Heating (ICRH) system antenna. The new antenna will be capable of providing 8 MW per square meter to the plasma surface.
