JET upgrade planned.An upgrade of the neutral beam system on the Joint European Torus
JET, the Joint European Torus, is the largest nuclear fusion experimental reactor yet built. (JET) in the UK, planned for installation in 2008, will deliver 35 MW of power for up to 20 seconds, compared to the 22 MW for 10 seconds currently available. The system can also be used to provide about 18 MW for 40 seconds. The upgrade will allow scientists to study ITER ITER. A foot way.

In particular, the improved facility should contribute to the demonstration of high density scenarios compatible with a metallic wall as foreseen fore·see tr.v. fore·saw , fore·seen , fore·see·ing, fore·sees To see or know beforehand: foresaw the rapid increase in unemployment. in ITER by including installation of a metal wall in JET. The neutral beam power will be increased primarily by changing the magnetic configuration of the ion sources Ion sources Devices which produce positive or negative electrically charged atoms or molecules. In general, ion sources fall into three major categories: those designed for positive-ion generation, those for negative-ion generation, and a highly . Other changes include replacement of eight of the existing 80kV/60A power supplies with 130kV/130A units. |
