JET operates at maximum performance

On the last two days of experimental activity of the C26 JET Campaign—6-7 April—JET was able to operate at plasma currents up to 4.3 MegaAmpere. Since 1996-97, JET had not operated in Type-I ELMy H-mode, which is the standard operation scenario planned for ITER, at this value of plasma current.

This is an important result since it shows that the machine can be operated reliably close to its maximum performance. The availability of more heating power, already envisaged in C27, will make it possible to investigate high confinement H-modes at high plasma current.
