TEXTOR

Was the largest fusion experiment at Jülich for 30 years until 2013. The mission of it was to expose the inner wall with heat and particle loads at intensities relevant for ITER and future reactors already today. TEXTOR was a test bed for wall materials of fusion reactors. Furthermore, a Dynamic Ergodic Divertor (DED) allowed for efficient control of instabilities in the fusion plasma.

TEXTOR was a fusion experiment of the tokamak type for technology-oriented research in the field of plasma wall interactions. This included detailed investigation of particle and energy transport between plasma and the plasma-facing wall as well as optimization of the wall and the edge plasma. A major target was to reduce particle erosion and release of impurities from the wall and impact of impurities on the plasma core to acceptable levels. For this purpose, TEXTOR had corresponding features such as:

Excellent access for plasma diagnostics to regions close to the wall,
Large ports in the plasma chamber for application of methods influencing the plasma edge,
Facilities for heating of the plasma chamber and the insert of it (liner),
Facilities for replacement of the liner.

In several enhancements, TEXOR was equipped with:

Auxiliary heating systems (neutral beam injectors, radio frequency heating, micro wave heating),
Pumped toroidal limiter,
Upgraded magnetizing coil,
Dynamic Ergodic Divertor.
