Abstract

ALT-II takes advantage of TEXTOR design features through the use of a new liner, adapted for installation of the toroidal belt limiter. The new liner facilitates an easier integration of the pump limiter. It also minimises TEXTOR down-time, as operation with the previous liner can be continued while trial installation of limiter modules is carried out with the new liner outside TEXTOR, before interrupting TEXTOR operations. Since the ALT-II belt limiter would have intersected the previously installed ICRH antennae, a new set of antennae had to be designed. The ALT-II limiter components were brought into the machine through one of the pumping ports. During the assembly work, the vessel was vented with filtered pressurised air at a slight excess pressure in order to minimise dust pollution. The new liner and the antennae are described in detail, and the integration of the ALT-II components in TEXTOR is also reviewed.
