Research activities:
The EURATOM Associations Belgian State (ERM/KMS Brussels), FOM (Nieuwegein, The Netherlands) and Forschungszentrum Jülich cooperate as the Trilateral Euregio Cluster (TEC), the central facility being the TEXTOR tokamak. The joint research programme of the TEC partners aims at developing a coherent concept for energy and particle transport/exhaust under quasi-stationary conditions. TEXTOR (R = 1.75 m, a = 0.5 m) is equipped with a toroidal pump limiter (ALT-II) and with a heating power of - up to now - 4.0 MW NBI and 4.0 MW ICRH (the latter provided by the Belgian TEC partner), thus achieving a power flux density through the boundary of 25 W/cm2. Fusion relevant plasmas can be produced and maintained for a duration of up to about 10 seconds. TEXTOR was several times adjusted to the increasing demands of the experimental programme by innovative upgrading measures. At present the Dynamic Ergodic Divertor (DED) and a high-power long-pulse ECRH system (the latter provided by the Dutch TEC partner) are being implemented.
The essence of the programme of Forschungszentrum Jülich is plasma-well technology with emphasis on heat removal and particle exhaust under long-pulse high-power heating conditions. Related issues of plasma confinement and transport are also addressed. The experimental programme is strongly supported by computer simulation and modelling of the relevant processes in plasma surface interaction. Further teststands for applying extremely high heat loads on first-wall components and materials, both by ions and electrons, are available.
The programme is oriented towards the physical and technological needs of ITER, the intensive scientific exploitation of JET, and the development of several diagnostics for the stellarator project Wendelstein 7-X.
Collaboration with the Universities in Belgium, The Netherlands and Nordrhein-Westfalen is promoted by the Euregional University Club of High-Temperature Plasma Physics (ECPP). Strong intercontinental links are established through IEA Implementing Agreement on TEXTOR (partners: Canada, EURATOM, Japan, USA).
Highlights of the TEXTOR programme:
wall conditioning (boronisation/siliconisation), erosion and deposition, helium exhaust, confinement physics esp. RI-mode, energy and particle transport, runaway electrons, MHD effects, magnetic turbulence.
