Fusion reactor JET in Culham, UK, is acting like a totally new device, courtesy of its brand new inner wall made out of tungsten and beryllium. For instance, fast disruptions of the plasma now leak more heat to the wall, but paradoxically these disruptions cause far fewer problems when restarting the plasma in subsequent experiments. Plasma physicist Dr. Peter de Vries from FOM-DIFFER, together with an international team, describes the results of a year's experimenting at JET in the 22 November issue of Plasma Physics and Controlled Fusion. The experiments are a step to transforming JET into a test bed for the advanced fusion reactor ITER.
