The flexible Heliac TJ-II is a medium size device (R=1.5 m, <a>=0.2 m,
B(0)=1.0 T) in an advanced stage of construction at Centro de Investi
gaciones Energeticas MedioAmbientales y Tecnologicas (CIEMAT), Madrid.
The problems encountered during manufacturing so far have been solved
satisfactory. Nevertheless the narrow tolerances, which result from t
he compact machine design, create real challenges for all the componen
t manufacturers. In this paper we present the present status of the pr
oject with a particular emphasis on the construction situation of the
main components.
